CRLF injection vulnerability in the mod_negotiation module in the Apache HTTP Server 2.2.6 and earlier in the 2.2.x series, 2.0.61 and earlier in the 2.0.x series, and 1.3.39 and earlier in the 1.3.x series allows remote authenticated users to inject arbitrary HTTP headers and conduct HTTP response splitting attacks by uploading a file with a multi-line name containing HTTP header sequences and a file extension, which leads to injection within a (1) "406 Not Acceptable" or (2) "300 Multiple Choices" HTTP response when the extension is omitted in a request for the file.

Security readout for executives and security teams

CVE-2008-0456 is an old Apache HTTP Server issue where a logged-in user who can upload files may influence HTTP responses through a specially formed filename. The business risk is mainly legacy exposure: affected servers could enable response splitting or header injection, which may support web attacks against users or intermediaries. Exposure is most likely on legacy Apache HTTP Server deployments using mod_negotiation and allowing authenticated users to upload files. Modern supported packages are less likely affected, but older appliances, embedded systems, and abandoned servers should be checked. Treat this as a legacy hygiene and exposure-reduction item, not an emergency based on the supplied evidence. Prioritize internet-facing or user-uploading Apache systems, especially unsupported servers where old httpd packages may persist. Mitigation focus: Inventory Apache HTTP Server versions and identify 1.3.x, 2.0.x, and 2.2.x legacy systems.; Apply vendor-supported Apache httpd updates from the relevant operating system or package vendor.; Review vendor advisories before relying on configuration-only workarounds..
