This Metasploit module creates a RAR file that exploits CVE-2022-30333, which is a path-traversal vulnerability in unRAR that can extract an arbitrary file to an arbitrary location on a Linux system. UnRAR fixed this vulnerability in version 6.12 (open source version 6.1.7). The core issue is that when a symbolic link is unRARed, Windows symbolic links are not properly validated on Linux systems and can therefore write a symbolic link that points anywhere on the filesystem. If a second file in the archive has the same name, it will be written to the symbolic link path.

Hello everyone! It has been 3 months since the last episode. I spent most of this time improving my Vulristics project. So in this episode, let’s take a look at what’s been done. Alternative video link (for Russia): https://vk.com/video-149273431_456239139 Also, let’s take a look at the Microsoft Patch Tuesdays vulnerabilities, Linux Patch Wednesdays vulnerabilities and […]

A malicious actor released a fake proof-of-concept (PoC) exploit for a recently disclosed WinRAR vulnerability on GitHub with an aim to infect users who downloaded the code with VenomRAT malware. "The fake PoC meant to exploit this WinRAR vulnerability was based on a publicly available PoC script that exploited a SQL injection vulnerability in an application called GeoServer, which is tracked as

Gentoo Linux Security Advisory 202309-4 - An arbitrary file overwrite vulnerability has been discovered in RAR and UnRAR, potentially resulting in arbitrary code execution. Versions greater than or equal to 6.23 are affected.

Hello everyone! This month I decided NOT to make an episode completely dedicated to Microsoft Patch Tuesday. Instead, this episode will be an answer to the question of how my Vulnerability Management month went. A retrospection of some kind. Alternative video link (for Russia): https://vk.com/video-149273431_456239134 GitHub exploits and Vulristics This month I made some improvements […]

A recently patched security flaw in the popular WinRAR archiving software has been exploited as a zero-day since April 2023, new findings from Group-IB reveal. The vulnerability, cataloged as CVE-2023-38831, allows threat actors to spoof file extensions, thereby making it possible to launch malicious scripts contained within an archive that masquerades as seemingly innocuous image or text files.

(Read more...) The post Update now! WinRAR files can be abused to run malware appeared first on Malwarebytes Labs.

A high-severity security flaw has been disclosed in the WinRAR utility that could be potentially exploited by a threat actor to achieve remote code execution on Windows systems. Tracked as CVE-2023-40477 (CVSS score: 7.8), the vulnerability has been described as a case of improper validation while processing recovery volumes. "The issue results from the lack of proper validation of user-supplied

Attackers are targeting Zimbra systems in the public and private sectors, looking to exploit multiple vulnerabilities, CISA says.

Multiple high-severity security flaws have been disclosed as affecting Juniper Networks devices, some of which could be exploited to achieve code execution. Chief among them is a remote pre-authenticated PHP archive file deserialization vulnerability (CVE-2022-22241, CVSS score: 8.1) in the J-Web component of Junos OS, according to Octagon Networks researcher Paulos Yibelo. "This vulnerability

Mitigation guidance provided while a patch is being developed

A severe remote code execution vulnerability in Zimbra's enterprise collaboration software and email platform is being actively exploited, with no patch currently available to remediate the issue. The shortcoming, assigned CVE-2022-41352, carries a critical-severity rating of CVSS 9.8, providing a pathway for attackers to upload arbitrary files and carry out malicious actions on affected

As many as 350,000 open source projects are believed to be potentially vulnerable to exploitation as a result of a security flaw in a Python module that has remained unpatched for 15 years. The open source repositories span a number of industry verticals, such as software development, artificial intelligence/machine learning, web development, media, security, IT management. The shortcoming,

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a recently disclosed security flaw in the UnRAR utility to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. Tracked as CVE-2022-30333 (CVSS score: 7.5), the issue concerns a path traversal vulnerability in the Unix versions of UnRAR that can be triggered upon extracting a

Other applications using binary to extract untrusted archives are potentially vulnerable too

A new security vulnerability has been disclosed in RARlab's UnRAR utility that, if successfully exploited, could permit a remote attacker to execute arbitrary code on a system that relies on the binary. The flaw, assigned the identifier CVE-2022-30333, relates to a path traversal vulnerability in the Unix versions of UnRAR that can be triggered upon extracting a maliciously crafted RAR archive.

RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and Android RAR are unaffected.
