Description:
A vulnerability has been reported in TWiki, which can be exploited by malicious people to disclose certain sensitive information.
The vulnerability exists due to an error when handling failed login attempts. This can be exploited to bypass authentication and view content in access restricted topics by canceling a login attempt with a valid user name.
Successful exploitation requires that "ErrorDocument 401" is set to a TWiki topic, that ApacheLogin with TWiki-4.0 is used with sessions enabled or SessionPlugin is used for older versions, and TWiki is running on Apache 1.3.
The vulnerability is reported in versions TWikiRelease01Sep2004 through TWikiRelease04Sep2004 with SessionPlugin, and 4.0.0 through 4.0.5.
