Arbitrary file upload and remote code execution in Koollab LMS allows an authenticated module designer to achieve full server compromise by uploading a malicious SCORM package containing a PHP webshell. The uploaded file is placed in a publicly accessible directory, enabling the attacker to execute arbitrary commands on the underlying server. No evidence of active exploitation or public exploit code exists at this time, but the CVSS score of 9.9 reflects critical severity.

Priority Score
Attack Technique
Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
