Summary
Koha Library before 23.05.10 fails to sanitize user-controllable filenames prior to unzipping, leading to remote code execution. The line "qx/unzip $filename -d $dirname/;" in upload-cover-image.pl is vulnerable to command injection via shell metacharacters because input data can be controlled by an attacker and is directly included in a system command, i.e., an attack can occur via malicious filenames after uploading a .zip file and clicking Process Images.
