CVE-2008-0456: Apache HTTPD: CRLF injection in mod_negotiation

CVE ID

CVE-2008-0456

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.

Unitrends assessment: Medium Risk.

RESOLUTION

If running CentOS5, update the httpd version.

Fixed in:

  • CentOS5 with httpd-2.2.3-74.el5
  • CentOS6 distribution already contains the fix.
To update to the new version with the fix, either do 'yum update httpd’ from the command line, or perform an update from the UI.
