CVE-2021-32644

Status: ModifiedMedium (5.4)—💥 PoC

Ampache is an open source web based audio/video streaming application and file manager. Due to a lack of input filtering versions 4.x.y are vulnerable to code injection in random.php. The attack requires user authentication to access the random.php page unless the site is running in demo mode. This issue has been resolved in 4.4.3.

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
