The Apache HTTP Server 2.0.44, when DNS resolution is enabled for client IP addresses, allows remote attackers to inject arbitrary text into log files via an HTTP request in conjunction with a crafted DNS response, as demonstrated by injecting XSS sequences, related to an "Inverse Lookup Log Corruption (ILLC)" issue.

Security readout for executives and security teams

This issue affects Apache HTTP Server 2.0.44 when it resolves client IP addresses through DNS. A remote party who can influence DNS responses may cause misleading or malicious text to appear in web server logs, including XSS-like content for vulnerable log viewers. Exposure is most likely where Apache HTTP Server 2.0.44 still exists and hostname lookup or DNS-based client name logging is enabled. Risk increases if logs are viewed in web-based analyzers that render log content unsafely. Prioritize this for legacy Apache environments and teams that rely on logs for investigations or expose web-based log dashboards. It is not supported by KEV evidence, but it can undermine log integrity and may affect administrators through unsafe log viewing. Mitigation focus: Check vendor guidance for supported Apache versions and applicable fixes.; Disable client hostname DNS resolution where it is not operationally required.; Treat all log fields as untrusted input in log viewers and reports..
