The U.S. Cybersecurity and Infrastructure Security Company (CISA) on Tuesday added a a short while ago disclosed security flaw in the UnRAR utility to its Regarded Exploited Vulnerabilities Catalog, dependent on evidence of energetic exploitation.
Tracked as CVE-2022-30333 (CVSS score: 7.5), the issue problems a route traversal vulnerability in the Unix versions of UnRAR that can be activated upon extracting a maliciously crafted RAR archive.
This means that an adversary could exploit the flaw to fall arbitrary data files on a target process that has the utility put in simply just by decompressing the file. The vulnerability was disclosed by SonarSource researcher Simon Scannell in late June.
“RARLAB UnRAR on Linux and UNIX has a directory traversal vulnerability, allowing for an attacker to produce to information throughout an extract (unpack) procedure,” the agency claimed in an advisory.
Not much is identified about the character of the attacks, but the disclosure is proof of a escalating pattern wherein menace actors are swift to scan for vulnerable techniques right after flaws are publicly disclosed and get the prospect to start malware and ransomware campaigns.
On prime of that, CISA has also included CVE-2022-34713 to the catalog following Microsoft, as section of its Patch Tuesday updates on August 9, disclosed that it has witnessed indications that the vulnerability has been exploited in the wild.
Stated to be a variant of the vulnerability publicly known as DogWalk, the shortcoming in the Microsoft Windows Assist Diagnostic Software (MSDT) component could be leveraged by a rogue actor to execute arbitrary code on prone programs by tricking a victim into opening a decoy file.
Federal companies in the U.S. are mandated to use the updates for both of those flaws by August 30 to lower their publicity to cyberattacks.
