CVE-2003-0020: Apache HTTP Server

Medium severity, CVSS 5.0. EPSS: 16.5% chance of exploitation in the next 30 days.

Apache does not filter terminal escape sequences from its error logs, which could make it easier for attackers to insert those sequences into terminal emulators containing vulnerabilities related to escape sequences.

Affected products

• Apache HTTP Server: from 1.3.0, before 1.3.31 (fixed in 1.3.31); from 2.0.0, before 2.0.49 (fixed in 2.0.49)
