What is CVE-2024-36057?

The Koha Library before version 23.05.10 contains a vulnerability where user-controllable filenames are not properly sanitized when extracting uploaded .zip files. This flaw allows attackers to perform command injection through crafted filenames in the 'upload-cover-image.pl' script. If an attacker uploads a .zip file with a malicious filename and initiates the image processing, they could execute arbitrary commands on the server, leading to potential unauthorized access and control over the impacted system.
