CVE-2006-4110

Status: ModifiedMedium (4.3)—💥 Exploit

Apache 2.2.2, when running on Windows, allows remote attackers to read source code of CGI programs via a request that contains uppercase (or alternate case) characters that bypass the case-sensitive ScriptAlias directive, but allow access to the file on case-insensitive file systems.

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.
