Red Hat Bugzilla – Bug 200738
CVE-2006-3918 Expect header XSS
Last modified: 2007-11-30 17:06:55 EST
+++ This bug was initially created as a clone of Bug #200732 +++ In May 2006 a reporter found a bug in Apache where an invalid Expect header sent to the server (Apache 1.3.3 onwards) would be returned to the user in an error message, unescaped. This could allow a cross-site scripting attack only if a victim can tricked into connecting to a site and sending such a carefully crafted Expect header. Whist browsers do not provide this functionality, it was recently discovered that Flash allows you to make a connection with arbitrary headers. The attack mechanism is therefore: 1. User is tricked into visiting a malicious web site with a flash-enabled browser 2. Malicious web site uses a flash movie to make a connection to the target site with custom Expect header 3. This results in cross-site scripting (attacker could steal your cookies from the third party site, or inject content etc) Patch: http://svn.apache.org/viewcvs?rev=394965&view=rev [1.3]
