Path Traversal in MHolt Archiver
Quick fix
GHSA-h74j-692g-48mq — github.com/mholt/archiver: upgrade to the fixed version with the command below.
go get github.com/mholt/archiver@v3.3.2Details
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.
