CVE-2020-37113

Status: AnalyzedHigh (8.7)—

GUnet OpenEclass 1.7.3 allows authenticated users to bypass file extension restrictions when uploading files. By renaming a PHP file to .php3 or .PhP, an attacker can upload a web shell and execute arbitrary code on the server. This vulnerability enables remote code execution by bypassing the intended file type checks in the exercise submission feature.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
