CVE-2004-0173

Status: ModifiedMedium (5)—💥 Exploit

Directory traversal vulnerability in Apache 1.3.29 and earlier, and Apache 2.0.48 and earlier, when running on Cygwin, allows remote attackers to read arbitrary files via a URL containing "..%5C" (dot dot encoded backslash) sequences.

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.
