Status: AnalyzedCritical (9.3)—

TinyWebGallery v2.5 contains a remote code execution vulnerability in the admin upload functionality that allows unauthenticated attackers to upload malicious PHP files. Attackers can upload .phar files with embedded system commands to execute arbitrary code on the server by accessing the uploaded file's URL.

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).

🎯 ATT&CK techniques
