CISA Issues Warning on Active Exploitation of UnRAR Software for Linux Systems

CISA Issues Warning on Active Exploitation of UnRAR Software for Linux Systems

Aug 10, 2022
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 maliciously crafted RAR archive. This means that an adversary could exploit the flaw to drop arbitrary files on a target system that has the utility installed simply by decompressing the file. The vulnerability was  revealed  by SonarSource researcher Simon Scannell in late June. "RARLAB UnRAR on Linux and UNIX contains a directory traversal vulnerability, allowing an attacker to write to files during an extract (unpack) operation," the agency  said  in an advisory. Although the flaw affects any Linux application that uses UnRAR to extract an archive file, a successful exploitation of

New UnRAR Vulnerability Could Let Attackers Hack Zimbra Webmail Servers

Jun 29, 2022
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. Following responsible disclosure on May 4, 2022, the shortcoming was addressed by RarLab as part of  version 6.12  released on May 6. Other versions of the software, including those for Windows and Android operating systems, are not impacted. "An attacker is able to create files outside of the target extraction directory when an application or victim user extracts an untrusted archive," SonarSource researcher Simon Scannell  said  in a Tuesday report. "If they can write to a known location, they are likely to be able to leverage it in a way leading to the execution of arb

6 Ways to Simplify SaaS Identity Governance

Feb 21, 2024SaaS Security / Identity Management
With SaaS applications now making up the vast majority of technology used by employees in most organizations, tasks related to identity governance need to happen across a myriad of individual SaaS apps. This presents a huge challenge for centralized IT teams who are ultimately held responsible for managing and securing app access, but can't possibly become experts in the nuances of the native security settings and access controls for hundreds (or thousands) of apps. And, even if they could, the sheer volume of tasks would easily bury them. Modern IT teams need a way to orchestrate and govern SaaS identity governance by engaging the application owners in the business who are most familiar with how the tool is used, and who needs what type of access.  Nudge Security is a  SaaS security and governance solution  that can help you do just that, with automated workflows to save time and make the process manageable at scale. Read on to learn how it works. 1 . Discover all SaaS apps used b
