A vulnerability, which was classified as problematic, has been found in DataGear up to 4.5.1. Affected by this issue is some unknown functionality of the component JDBC Server Handler. The manipulation leads to deserialization. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-225920. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Description： DataGear is an open source and free data visualization and analysis platform, free to create any data dashboard you want, and supports access to various data sources such as SQL, CSV, Excel, HTTP interface, and JSON. In Datagear 4.5.1 and earlier, an attacker can achieve jdbc deserialization attacks by uploading a vulnerable version of the mysql driver. After the upload is successful, an unauthenticated attacker can construct a malicious request to connect to a malicious JDBC server to trigger deserialization.

Version: datagear <= 4.5.1

Add:https://github.com/datageartech/datagear

Vulnerability recurrence:

1.login system. Upload the mysql driver with jdbc deserialization vulnerability version  

2.Make URLDNS deserialized data

3.Set up mysql\_fake server

4.Find the data source, select the driver we added, and fill in the payload that triggers the vulnerability(removing cookies can also trigger the vulnerability)

The post Apple releases emergency updates for two known-to-be-exploited vulnerabilities appeared first on Malwarebytes Labs.

On Friday April 7, 2023, Apple released iOS 16.4.1, iPadOS 16.4.1, and macOS 13.3.1 for the iPhone, iPad, and Mac, respectively, and our advice is to install them as soon as possible because all three updates include important security fixes.

The Cybersecurity and Infrastructure Security Agency (CISA) has already ordered federal agencies to patch these two security vulnerabilities before May 1st, 2023.

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.

**The vulnerabilities**

The security content of iOS 16.4.1 and iPadOS 16.4.1 contains information about two vulnerabilities that Apple has been made aware of reports that these issue may have been actively exploited.

CVE-2023-28206: an out-of-bounds write issue in IOSurfaceAccelerator was addressed with improved input validation. The issue that could allow an app to execute arbitrary code with kernel privileges is fixed in iOS 15.7.5 and iPadOS 15.7.5, macOS Monterey 12.6.5, iOS 16.4.1 and iPadOS 16.4.1, macOS Big Sur 11.7.6, macOS Ventura 13.3.1.

IOSurfaceAccelerator is an object that manages hardware accelerated transfers/scales between IOSurfaces in the IOSurface framework. The IOSurface framework provides a framebuffer object suitable for sharing across process boundaries. It is commonly used to allow applications to move complex image decompression and draw logic into a separate process to enhance security.

An out-of-bounds write can occur when a program writes outside the bounds of an allocated area of memory, potentially leading to a crash or arbitrary code execution. This can happen when the size of the data written is larger than the size of the allocated memory area, when the data is written to an incorrect location within the memory area, or when the program incorrectly calculates the size or location of the data to be written. In this case an attacker can use it to elevate the privileges of a malicious app. For those interested, a proof-of-concept (PoC) has been published for this vulnerability.

CVE-2023-28205: a use after free (UAF) issue was addressed with improved memory management. This issue is fixed in iOS 15.7.5 and iPadOS 15.7.5, Safari 16.4.1, iOS 16.4.1 and iPadOS 16.4.1, macOS Ventura 13.3.1.

UAF is a type of vulnerability that is the result of the 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. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. In this case, when the vulnerability is exploited, processing maliciously crafted web content may lead to arbitrary code execution.

WebKit is Apple’s web rendering engine. In other words, WebKit is the browser engine that powers Safari and other apps.

The security content of macOS Ventura 13.3.1 covers the same two vulnerabilities and Apple has also released a new Safari 16.4.1 update for macOS Monterey and macOS Big Sur, which likely addresses the WebKit vulnerability.

Apple releases emergency updates for two known-to-be-exploited vulnerabilities

Unpatched Macs, iPhones, and iPads open to browser takeover and system kernel-level malicious code execution, Apple warns.

On April 7, Apple released two security updates warning about two zero-day vulnerabilities under active exploit in the wild. By April 10, those were added to the Cybersecurity and Infrastructure Security Agency (CISA) known exploited vulnerabilities (KEV) list.

The impact of the two vulnerabilities is widespread, affecting macOS Ventura 13.3.1 for Apple Macs, in addition to the iOS 16.4.1 and iPadOS 16.4.1 operating systems used to run iPhones and iPads, according to Apple.

The first bug, CVE-2023-28205, is a flaw in Apple iOS, iPad OS, macOS, and Safari WebKit that could lead to code injection while processing malicious Web content, CISA explained. The second, CVE-2023-28206, affects Apple iOS, iPadOS, and macOS IOSurfaceAccelerator that, worryingly, could allow a malicious app to execute code with kernel privileges, CISA said.

Apple has issued updates for iOS 16 and iPad OS 16. Other macOS versions including Big Sur Monterey, and Ventura have patches that need to be installed, and as Sophos pointed out in a separate advisory, it's still unclear whether the bugs will impact iOS 15 users with older devices.

Both issues were reported by Clément Lecigne of Google's Threat Analysis Group and Donncha Ó Cearbhaill of Amnesty International's Security Lab, giving cybersecurity experts reason to believe the flaws are being exploited by state actors to deploy spyware.

"It is interesting that Amnesty International's Security Lab was one of the organizations involved in finding reporting the issue," Mike Parkin, senior technical engineer with Vulcan Cyber explained in a statement provided to Dark Reading. "While Apple hasn't said much about the exploits, it seems likely, given the reporting and earlier history, that the exploits were deployed by state-level threat actors."
