Summary
ILIAS from 9.0 before 9.24, from 10.0 before 10.12, and from 11.0 before 11.5 is affected. The assImagemapQuestionGUI component passes tab-separated options in uploaded image filenames to ImageMagick, and escapeshellcmd() does not neutralise them (CWE-88). A question author with low privileges can upload a crafted filename that writes a PHP file under the web root, which allows remote code execution.

Description from the CNA
ILIAS before 9.24, 10.x before 10.12 and 11.x before 11.5 contains an argument injection vulnerability in assImagemapQuestionGUI that allows question authors to inject ImageMagick convert options via uploaded image filenames. Attackers can embed tab-separated options, which escapeshellcmd() does not neutralise, to write a PHP file under the web root and achieve remote code execution.
