CVE-2022-44006

Status: ModifiedCritical (9.8)—

An issue was discovered in BACKCLICK Professional 5.9.63. Due to improper validation or sanitization of upload filenames, an externally reachable, unauthenticated update function permits writing files outside the intended target location. Achieving remote code execution is possible, e.g., by uploading an executable file.

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).
