FKIE_CVE-2003-0993
Vulnerability from fkie_nvd - Published: 2004-03-29 05:00 - Updated: 2026-06-16 22:03
Severity
Summary
mod_access in Apache 1.3 before 1.3.30, when running big-endian 64-bit platforms, does not properly parse Allow/Deny rules using IP addresses without a netmask, which could allow remote attackers to bypass intended access restrictions.
