K17189 : Apache HTTP server vulnerability CVE-2008-0456

Security Advisory Description

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. (CVE-2008-0456)

Impact

An authenticated attacker, with command line access, may be able to impact the integrity of authenticated users by configuring Apache to serve a specially crafted file on the local file system. There is no data plane exposure; only the control plane is exposed.
