CVE-2019-10743: Archiver Project Archiver

Medium severity, CVSS 5.5. EPSS: 6.4% chance of exploitation in the next 30 days.

All versions of archiver allow attacker to perform a Zip Slip attack via the "unarchive" functions. It is exploited using a specially crafted zip archive, that holds path traversal filenames. When exploited, a filename in a malicious archive is concatenated to the target extraction directory, which results in the final path ending up outside of the target folder. For instance, a zip may hold a file with a "../../file.exe" location and thus break out of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.

Affected products

• Archiver Project Archiver: from 3.0.0, before 3.3.2 (fixed in 3.3.2)
