SexyPolling SQL Injection

====================

| Identifier: | AIT-SA-20220208-01|  
| Target: | Sexy Polling ( Joomla Extension) |  
| Vendor: | 2glux |  
| Version: | all versions below version 2.1.8 |  
| CVE: | Not yet |  
| Accessibility: | Remote |  
| Severity: | Critical |  
| Author: | Wolfgang Hotwagner (AIT Austrian Institute of Technology) |

Summary

========

[Sexy Polling is a Joomla Extension for votes.](https://2glux.com/projects/sexypolling). In all versions below 2.1.8 an unauthenticated attacker could execute arbitrary SQL commands by sending crafted POST-parameters to poll.php.

Vulnerability Description

====================

In the vote.php file, the POST parameters min_date and max_date are insufficiently checked and sanitized. An attacker can use these parameters to send payloads for sql injections.

In lines 74 and 75 in the *site/vote.php* code, the parameters are assigned without being checked:

```  
$min_date_sent = isset($_POST['min_date']) ? $_POST['min_date'].' 00:00:00' : '';  
$max_date_sent = isset($_POST['max_date']) ? $_POST['max_date'].' 23:59:59' : '';  
```

These are later used unfiltered by the WHERE clause:

```  
$query_toal = "SELECT  
COUNT(sv.`id_answer`) total_count,  
MAX(sv.`date`) max_date,  
MIN(sv.`date`) min_date  
FROM  
`#__sexy_votes` sv  
JOIN  
`#__sexy_answers` sa ON sa.id_poll = '$polling_id'  
AND  
sa.published = '1'  
WHERE  
sv.`id_answer` = sa.id";

//if dates are sent, add them to query  
if ($min_date_sended != '' && $max_date_sended != '')  
$query_toal .= " AND sv.`date` >= '$min_date_sended' AND sv.`date` <= '$max_date_sended' ";  
```

Proof Of Concept

==============

To check a system for vulnerability, modify the POST request so that the min_date parameter contains a single apostrophe.

Joomla SexyPolling 2.1.7 SQL Injection

Founders Fund leads $100 million Series-C financing, gaining the email security startup unicorn status two years after its launch.

Redwood City, Calif., May 11, 2022 – Material Security, a company that can protect email accounts even after they have been compromised, today announced it has secured $100 million in Series-C funding at a valuation of $1.1 billion. The round is led by Founders Fund, with participation from previous backers Andreesen Horowitz, Silicon Valley solo capitalist Elad Gil and other high-profile individual tech investors, gaining the company unicorn status just two years after the official launch of its product suite. Material Security is also announcing new referenceable customers including Chubb, Compass, Roblox and Brex, to add to leading brands like Lyft, Mars, Databricks and DoorDash.

Founded by former Dropbox technologists in the wake of the 2016 Election Hack, Material Security is a pioneer of using “zero trust” security techniques to protect email. Its patented security technology is trusted by government agencies, media and manufacturing conglomerates, leading financial institutions, the most targeted companies in Silicon Valley, and high-profile personalities including billionaires and celebrities.

“The fundamental idea behind ‘zero trust’ is that it assumes a bad actor is going to find a way past the perimeter into your systems. But historically, email security has just focused on blocking suspicious messages,” said Ryan Noon, co-founder and CEO of Material Security. “Whether it’s a large global organization like News Corp. or a local health care provider, we are still seeing an overwhelming number of email and data security breaches occur on a regular basis. At Material, we begin with the assumption that a hacker is already in your email and limit the damage they can do.”

Material’s Leak Prevention feature, for example, automatically redacts sensitive content in email, keeping it safe in the event of a breach. Users can still access original messages via identity-protection apps that their company already uses. “Not all emails are created equal,” said Abhishek Agrawal, co-founder and CTO of Material Security. "Some messages are so critical that they deserve an extra layer of verification. But the way email works today is that it treats every message identically."

Bringing Material Security’s total investment to $166 million since its founding, this latest round of funding will be used to scale the company’s sales and marketing teams, extend the product into new areas (including a larger footprint in government) and expand internationally.

“As the U.S. government doubles down on ‘zero trust’ and organizations are increasingly vulnerable to cyber threats given geopolitical crises, Material Security is poised to minimize the risks associated with email hacks,” said Trae Stephens, partner at Founders Fund. “We are excited to partner with this innovative team at such a critical point in their growth trajectory.”

Europe’s proposed child protection laws could undermine end-to-end encryption for billions of people.

All of your WhatsApp photos, iMessage texts, and Snapchat videos could be scanned to check for child sexual abuse images and videos under newly proposed European rules. The plans, experts warn, may undermine the end-to-end encryption that protects billions of messages sent every day and hamper people’s online privacy.

The European Commission today revealed long-awaited proposals aimed at tackling the huge volumes of child sexual abuse material, also known as CSAM, uploaded to the web each year. The proposed law creates a new EU Centre to deal with child abuse content and introduces obligations for tech companies to “detect, report, block and remove” CSAM from their platforms. The law, announced by Europe’s commissioner for home affairs, Ylva Johansson, says tech companies have failed to voluntarily remove abuse content, and it has been welcomed by child protection and safety groups.

Under the plans, tech companies—ranging from web hosting services to messaging platforms—can be ordered to “detect” both new and previously discovered CSAM, as well as potential instances of “grooming.” The detection could take place in chat messages, files uploaded to online services, or on websites that host abusive material. The plans echo an effort by Apple last year to scan photos on people’s iPhones for abusive content before it was uploaded to iCloud. Apple paused its efforts after a widespread backlash.

If passed, the European legislation would require tech companies to conduct risk assessments for their services to assess the levels of CSAM on their platforms and their existing prevention measures. If necessary, regulators or courts may then issue “detection orders” that say tech companies must start “installing and operating technologies” to detect CSAM. These detection orders would be issued for specific periods of time. The draft legislation doesn’t specify what technologies must be installed or how they will operate—these will be vetted by the new EU Centre—but says they should be used even when end-to-end encryption is in place.

The European proposal to scan people’s messages has been met with frustration from civil rights groups and security experts, who say it’s likely to undermine the end-to-end encryption that’s become the default on messaging apps such as iMessage, WhatsApp, and Signal. “Incredibly disappointing to see a proposed EU regulation on the internet fail to protect end-to-end encryption,” WhatsApp head Will Cathcart tweeted. “This proposal would force companies to scan every person's messages and put EU citizens' privacy and security at serious risk.” Any system that weakens end-to-end encryption could be abused or expanded to look for other types of content, researchers say.

“You either have E2EE or you don’t,” says Alan Woodward, a cybersecurity professor from the University of Surrey. End-to-end encryption protects people’s privacy and security by ensuring that only the sender and receiver of messages can see their content. For example, Meta, the owner of WhatsApp, doesn’t have any way to read your messages or mine their contents for data. The EU’s draft regulation says solutions shouldn’t weaken encryption and says it includes safeguards to ensure this doesn’t happen; however, it doesn’t give specifics for how this would work.

“That being so, there is only one logical solution: client-side scanning where the content is examined when it is decrypted on the user's device for them to view/read,” Woodward says. Last year, Apple announced it would introduce client-side scanning—scanning done on people’s iPhones rather than Apple’s servers—to check photos for known CSAM being uploaded to iCloud. The move sparked protests from civil rights groups and even Edward Snowden about the potential for surveillance, leading Apple to pause its plans a month after initially announcing them. (Apple declined to comment for this story.)

For tech companies, detecting CSAM on their platforms and scanning some communications is not new. Companies operating in the United States are required to report any CSAM they find or that is reported to them by users to the National Center for Missing and Exploited Children (NCMEC), a US-based nonprofit. More than 29 million reports, containing 39 million images and 44 million videos, were made to NCMEC last year alone. Under the new EU rules, the EU Centre will receive CSAM reports from tech companies.

“A lot of companies are not doing the detection today,” Johansson said in a press conference introducing the legislation. “This is not a proposal on encryption, this is a proposal on child sexual abuse material,” Johansson said, adding that the law is “not about reading communication” but detecting illegal abuse content.

At the moment, tech companies find CSAM online in different ways. And the amount of CSAM found is increasing as tech companies get better at detecting and reporting abuse—although some are much better than others. In some cases, AI is being used to hunt down previously unseen CSAM. Duplicates of existing abuse photos and videos can be detected using “hashing systems,” where abuse content is assigned a fingerprint that can be spotted when it’s uploaded to the web again. More than 200 companies, from Google to Apple, use Microsoft's PhotoDNA hashing system to scan millions of files shared online. However, to do this, systems need to have access to the messages and files people are sending, which is not possible when end-to-end encryption is in place.

“In addition to detecting CSAM, obligations will exist to detect the solicitation of children (‘grooming’), which can only mean that conversations will need to be read 24/7,” says Diego Naranjo, head of policy at the civil liberties group European Digital Rights. “This is a disaster for confidentiality of communications. Companies will be asked (via detection orders) or incentivized (via risk mitigation measures) to offer less secure services for everyone if they want to comply with these obligations.”

Discussions about protecting children online and how this can be done with end-to-end encryption are hugely complex, technical, and combined with the horrors of the crimes against vulnerable young people. Research from Unicef, the UN’s children’s fund, published in 2020 says encryption is needed to protect people’s privacy—including children—but adds that it “impedes” efforts to remove content and identify the people sharing it. For years, law enforcement agencies around the world have pushed to create ways to bypass or weaken encryption. “I’m not saying privacy at any cost, and I think we can all agree child abuse is abhorrent,” Woodward says, “but there needs to be a proper, public, dispassionate debate about whether the risks of what might emerge are worth the true effectiveness in fighting child abuse.”

Increasingly, researchers and tech companies have been focusing on safety tools that can exist alongside end-to-encryption. Proposals include using metadata from encrypted messages—the who, how, what, and why of messages, not their content—to analyze people’s behavior and potentially spot criminality. One recent report by the nonprofit Business for Social Responsibility, which was commissioned by Meta, found that end-to-end encryption is an overwhelmingly positive force for upholding people's human rights. It suggested 45 recommendations for how encryption and safety can go together and not involve access to people’s communications. When the report was published in April, Lindsey Andersen, BSR's associate director for human rights, told WIRED: “Contrary to popular belief, there actually is a lot that can be done even without access to messages.”

The EU Wants Big Tech to Scan Your Private Chats for Child Abuse

May's Patch Tuesday includes one actively exploited zero-day vulnerability and some other interesting ones.
The post Update now! Microsoft releases patches, including one for actively exploited zero-day appeared first on Malwarebytes Labs.

Posted: May 11, 2022 by

Microsoft has released patches for 74 security problems, including fixes for seven “critical” vulnerabilities, and an actively exploited zero-day vulnerability that affects all supported versions of Windows.

First, we’ll look at the actively exploited zero-day. Then we’ll discuss two zero-days that are publicly disclosed, but so far no in the wild exploits have been reported. And we’ll finish off with a few others that are worth keeping an eye on.

**LSA spoofing zero-day**

Microsoft has addressed an actively exploited Windows LSA spoofing zero-day that allows unauthenticated attackers to remotely force domain controllers to authenticate them via the Windows NT LAN Manager (NTLM) security protocol.

CVE-2022-26925: An unauthenticated attacker could call a method on the LSARPC interface and coerce the domain controller to authenticate to the attacker using NTLM. The security update detects anonymous connection attempts in LSARPC and disallows it.

LSA (short for Local Security Authority) is a protected Windows subsystem that enforces local security policies and validates users for local and remote sign-ins. LSARPC is a protocol that enables a set of remote procedure calls (RPCs) to the LSA. Microsoft warns that the CVSS score would be 9.8 out of 10 when this vulnerability is chained with the noted NTLM Relay Attacks on Active Directory Certificate Services (AD CS).

The attack vector is closely related to the PetitPotam attacks we saw last year. If you are looking which patches to prioritize, this vulnerability affects all servers but domain controllers should be prioritized in terms of applying security updates.

**Windows Hyper-V vulnerability**

CVE-2022-22713: A denial of service (DoS) vulnerability in Windows Hyper V. Successful exploitation of this vulnerability requires an attacker to win a race condition. A race condition occurs when two or more threads can access shared data and they try to change it at the same time.

Hyper V is a native hypervisor, which means it can create virtual machines on x86-64 systems running Windows. The vulnerability only affects Windows Server (version 20H2) and Windows 10 x-64 based systems (versions 20H2 , 21H1, 21H2).

**Redshift driver**

CVE-2022-29972: A vulnerability that affects the Amazon Redshift ODBC and JDBC drivers and Amazon Athena ODBC and JDBC drivers due to improper validation of authentication tokens which may allow for unintended program invocation.

Microsoft products Azure Synapse Pipelines and Azure Data Factory are affected by a vulnerability in the Magnitude Simba Amazon Redshift ODBC Driver. An ODBC driver uses the Open Database Connectivity (ODBC) interface by Microsoft that allows applications to access data in database management systems (DBMS) using SQL (Structured Query Language) as a standard for accessing the data.

The vulnerability was dubbed SynLapse by the researchers that discovered it. They believe the tenant separation in the Microsoft Azure Synapse service is insufficiently robust to protect secrets against other tenants.

**Windows Network File System**

Next is a Remote Code Execution (RCE) vulnerability affecting Windows Network File System (NFS) listed under CVE-2022-26937. This vulnerability could be exploited over the network by making an unauthenticated, specially crafted call to a Network File System (NFS) service to trigger a Remote Code Execution (RCE). Microsoft considers it likely to be exploited and it is one of the highest-rated vulnerabilities of the month with a CVSS score of 9.8 out of 10.

**Point-to-Point Tunneling Protocol**

CVE-2022-21972: a Point-to-Point Tunneling Protocol Remote Code Execution vulnerability. An unauthenticated attacker could send a specially crafted connection request to a RAS server, which could lead to remote code execution (RCE) on the RAS server machine. A remote access server (RAS) is a type of server that provides a suite of services to remotely connected users over a network or the Internet.

CVE-2022-23270: another Point-to-Point Tunneling Protocol Remote Code Execution vulnerability. An unauthenticated attacker could send a specially crafted connection request to a RAS server, which could lead to remote code execution (RCE) on the RAS server machine.

Successful exploitation of these two vulnerabilities requires an attacker to win a race condition.
