Summary: CVE-2006-2769 Snort URIContent Rules Detection Evasion Vulnerability https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=193809 dennis@xxxxxxxx changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |CLOSED Resolution| |CURRENTRELEASE Fixed In Version| |2.6.0-1 ------- Additional Comments From dennis@xxxxxxxx 2006-06-29 07:34 EST ------- I was looking at thins last night. I have updated to 2.6.0 since and according to snort.org its fixed there Sourcefire is aware of a possible Snort evasion that exists in the http_inspect preprocessor. This evasion case only applies to protected Apache web servers. We have prepared fixes for both the 2.4 and 2.6 branches and will have fully tested releases, including binaries, available for both on Monday, June 5th. Evasion Details: The Apache web server supports special characters in HTTP requests that do not affect the processing of the particular request. The current target-based profiles for Apache in the http_inspect preprocessor do not properly handle these requests, resulting in the possibility that an attacker can bypass detection of rules that use the "uricontent" keyword by embedding special characters in a HTTP request. Background Information: It is important to note that this is an evasion and not a vulnerability. This means that while it is possible for an attacker to bypass detection, Snort sensors and the networks they protect are not at a heightened risk of other attacks. Timeline: Sourcefire has prepared fixes and is currently finalizing a complete round of testing to ensure that the fixes not only solve the issue at hand but do not create new bugs as well. The following releases, including binaries for Linux and Windows deployments, will be available on Monday, June 5th: * Snort v2.4.5 * Snort v2.6.0 final Questions: Any questions regarding these releases can be sent to snort-team@xxxxxxxxxxxxxxx -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
