WBCE CMS 1.6.1 Cross Site Scripting

Steam, the most popular video game storefront on PCs, only recently announced that it was ending support for Windows 7 and 8, and even then, it won’t be official until January.

Thursday, May 25, 2023 14:05

Welcome to this week’s edition of the Threat Source newsletter.

As a longtime macOS user, I must admit I’m behind the times when it comes to Microsoft Windows. Since buying a Steam Deck, I’ve actually come to learn more about Linux and the Proton compatibility layer than I ever did about Windows.

But it still came as a shock to me this week when I uncovered a weird trend on social media: People bragging about still using Windows 7.

Microsoft stopped putting out free security updates for Windows 7 in January 2020 and only more recently stopped offering its paid Extended Security Updates (ESU). The company explicitly told users at the beginning of this year that it was unsafe to continue to keep using Windows 7 and that users should upgrade to Windows 10 or use a new machine that can run Windows 11.

Yet I still found an entire subreddit dedicated to keeping Windows 7 up and running on computers and countless posts promoting how well the 13-year-old operating system runs with modern GPUs and graphics cards.

Steam, the most popular video game storefront on PCs, only recently announced that it was ending support for Windows 7 and 8, and even then, it won’t be official until January. And Roblox, which is quietly one of the biggest video games in the world, only recently ended support for Windows 7 and 8.

I’m sure there are other examples of this among other types of software, but video games are the most specific corner of the internet I’m in, so that’s my frame of reference.

The moral of the story here is that using Windows 7 to do anything, but especially connecting to the internet (which is required to download and play video games) is a terrible idea. Attackers are always targeting outdated operating systems because they’re the most likely to be unpatched and vulnerable.

Running an operating system that is no longer receiving any type of security updates is extremely dangerous. If infected, that single machine could also be used as a springboard for the attacker to target and infect other machines on your network.

Since the start of this year, there have been 47 vulnerabilities discovered in Windows 7, according to the U.S.’s National Institute of Standards and Technology Vulnerability Database. There are even more security issues with third-party software running on Windows 7.

Just because something is old, doesn’t mean that attackers aren’t paying attention anymore. Without official support or security updates for Windows 7, Microsoft is no longer compelled to disclose formal vulnerabilities with CVEs attached to inform users about any security holes in the operating system.

Upgrading a PC or buying a new one is expensive, I get it. But Windows 7 isn’t a novelty anymore, it’s a security risk. If you feel like you absolutely have to keep Windows 7 running on a machine for some reason, make sure it is isolated from your network or just doesn’t connect to the internet at all.

But more preferably, upgrade to Windows 10. If you’re already using Windows 7, it’s free, and likely whatever hardware you’re using can support Windows 10. If you’re starting from scratch, many online stores have deeply discounted product keys for Windows 10 or 11 for $20 or less — just make sure to download the ISO directly from Microsoft still.

**The one big thing**

Montana recently became the first state in the U.S. to ban the app TikTok, though the law still has a long way to go before it can be enforced. The state’s governor signed a bill last week that prohibits mobile application stores from offering the app in the state by the start of 2024, or else they’ll face fines. However, it’s currently unclear if it’s even feasible for Montana to enforce this ban, as app stores don’t geofence certain applications on its stores, and internet service providers are exempt from having to enforce these rules. TikTok has recently become a target for Republican lawmakers over concerns that its Chinese-backed parent company is collecting and using Americans’ data. TikTok and popular TikTok creators in Montana have already sued the state to stop the law.

**Why do I care?**

Even if you are not an active TikTok user, the ban is noteworthy because it has major implications for American law and the enforcement of the First Amendment in the U.S. Opponents of Montana’s bill say it's a clear violation of the First Amendment. The various legal challenges are likely going to shift through the legal system for months, but any eventual decisions could influence how states view banning certain technology or even books and movies.

**So now what?**

There are many questions still unanswered about how this ban will work or whether it will stand. So for now, interested parties can’t do much but sit back and wait for the legal proceedings to play out.

**Top security headlines of the week**

Apple released a security update for many of its devices last week that **fixed three zero-day vulnerabilities in the WebKit browser engine.** A few days after the patches initially dropped, security researchers also discovered the updates addressed a different vulnerability known as “ColdInvite” (CVE-2023-27930). An attacker could exploit ColdInvite to attack a co-processor chip on iPhones and escape its isolation environment, eventually accessing the iPhone’s kernel. The three WebKit vulnerabilities affect some iPhones and iPads. CVE-2023-28204, CVE-2023-32373 and CVE-2023-32409 could be exploited to escape the Web Content sandbox. Google’s Threat Analysis Group and Amnesty International co-reported CVE-2023-32409, which led many security experts to speculate means attackers exploited this issue to spread spyware. (SecurityWeek, Forbes)

**Two popular Android set-top TV boxes sold on Amazon are preloaded with malware** that quietly generates revenue for the manufacturers in the background. The devices click on ads while running without the user knowing and connect to a global botnet of other infected Android devices around the globe. Despite the reported security issues, the devices were still for sale on Amazon as of earlier this week. However, the security researcher who discovered this botnet worked with the internet company hosting the command and control servers that sent directions to devices part of the botnet to take those servers down. However, that doesn’t mean the botnet or ad-click malware could never come back — the easiest solution for users is to replace the devices immediately. (TechCrunch, ArsTechnica)

Security researchers are concerned that **two new top-level domains from Google — .zip and .mov — will cause confusion among users and potentially open the door for scammers.** Because these new TLDs (like .com, .gov, .uk, etc.) are the same as popular file extensions, adversaries could disguise legitimate-looking file names and actually send people to a malicious web address without the user knowing that it could even be a web page. They could also be used to create legitimate-looking URLs that match that of a real website but just add one character in a long string, eventually pointing people to a malicious file or site. However, Google says it's actively monitoring for domain abuse. (Wired, Ars Technica)

2023 Online Course Registration 1.0 SQL Injection

SofaWiki <= 3.8.9 has a file upload vulnerability that leads to command execution.

1.  The PHP file an be uploaded directly by matching referer.

    // index.php
    case 'uploadbigfile':   		if ($user->hasright('upload', '') || stristr($swBaseHrefFolder,$referer))
    							{
    									include 'inc/special/uploadbigfile.php';
    							}
    

    // uploadbigfile.php
    if (isset($_FILES['uploadedfile']) && is_uploaded_file($_FILES['uploadedfile']['tmp_name']))
    {	 
    	 $filename = $_FILES['uploadedfile']['name'];
    	 $newfile = $swRoot.'/site/uploadbig/'.$filename;
    	 move_uploaded_file($_FILES['uploadedfile']['tmp_name'],$newfile);
    	 
    	 $checksum = md5_file($newfile);
    	 if ($checksum == $filename)
    	 {
    		 echo 'upload ok '.$filename;
    	 }
    	 else
    	 {
    		 echo 'checksum error filename '.$filename.' checksum '.$checksum. ' length '.filesize($newfile);
    		 unlink($newfile);
    	 }
    	 
    	 $_FILES = null;
    	 
    	 exit();
    }
    

2.  Send a request package to get checksum.

Apple issued information about patches against three actively exploited zero-days in WebKit. One vulnerability is new, two were patched earlier this month.



(Read more...)




The post Update now! Apple issues patches for three actively used zero-days appeared first on Malwarebytes Labs.

Apple has rolled out security updates for Safari 16.5, watchOS 9.5, tvOS 16.5, iOS 16.5, iPadOS 16.5, iOS 15.7.6, iPadOS 15.7.6, macOS Big Sur 11.7.7, macOS Ventura 13.4, and macOS Monterey 12.6.6.

Among the security updates were patches for three actively exploited zero-day vulnerabilities. All these actively exploited vulnerabilities are directly related to the WebKit browser engine.

WebKit is the engine that powers the Safari web browser on Macs as well as all browsers on iOS and iPadOS (all web browsers on iOS and iPadOS are obliged to use it). It is also the web browser engine used by Mail, App Store, and many other apps on macOS, iOS, and Linux.

Devices impacted by the identified exploits include:

*   All iPad Pro models
*   iPad Air (3rd generation and later)
*   iPad (5th generation and later)
*   iPad Mini (5th generation and later)
*   iPhone 6s and later models
*   Mac workstations and laptops running macOS, Big Sur, Monterey, and Ventura
*   Apple Watch (series 4 and later)
*   Apple TV 4K and HD

The updates may already have reached you in your regular update routines, but it doesn't hurt to check if your device is at the latest update level. If a Safari update is available for your device, you can get it by updating or upgrading macOS, iOS, or iPadOS:

*   How to update your iPhone or iPad.
*   How to update macOS on Mac.

The Common Vulnerabilities and Exposures (CVE) database lists publicly disclosed computer security flaws. The CVE containing the information about the new zero-day is:

*   CVE-2023-32409: An issue where remote attacker may be able to break out of Web Content sandbox was addressed with improved bounds checks.

The notes about the security updates also revealed some information about the Apple’s Rapid Security Response (RSR) update we reported about earlier this month.

RSR is a new type of software patch delivered between Apple's regular, scheduled software updates. Previously, Apple security fixes came bundled along with features and improvements, but RSRs only carry security fixes. They're meant to make the deployment of security improvements faster and more frequent.

We now know that the CVEs patched in that RSR update are listed as:

*   CVE-2023-28204: An out-of-bounds read issue in WebKit was addressed with improved input validation. Processing web content may disclose sensitive information.
*   CVE-2023-32373: A use-after-free issue in WebKit which was addressed with improved memory management. Processing maliciously crafted web content may lead to arbitrary code execution.

An out-of-bounds write or read flaw makes it possible to manipulate parts of the memory which are allocated to more critical functions. This could allow an attacker to write code to a part of the memory where it will be executed with permissions that the program and user should not have.

Use after free (UAF) is a vulnerability due to incorrect use of dynamic memory during a program’s operation. If after freeing a memory location a program does not clear the pointer to that memory, an attacker can use the error to manipulate the program.

**We don’t just report on vulnerabilities—we identify them, and prioritize action.**

Cybersecurity risks should never spread beyond a headline. Keep vulnerabilities in tow by using Malwarebytes Vulnerability and Patch Management.
