Description:
A vulnerability and a security issue have been reported in TWiki, which can be exploited by malicious people to cause a DoS (Denial of Service) and bypass certain security restrictions.
1) The problem is that it is possible to view restricted content via the rdiff and preview scripts.
Example:
http://[host]/bin/preview/[restricted content]/WebHome?action=foo
The security issue has been reported in releases TWikiRelease04x00x01 and TWikiRelease04x00x00.
2) An error in the handling of circular references for the "%INCLUDE" statement can be exploited to cause an infinite recursion and consume a large amount of memory resources on a vulnerable system by supplying a URL which references itself.
The vulnerability has been reported in the following releases:
* TWikiRelease04x00x01
* TWikiRelease04x00x00
* TWikiRelease04Sep2004
* TWikiRelease03Sep2004
* TWikiRelease02Sep2004
* TWikiRelease01Sep2004
* TWikiRelease01Feb2003
