>> Bugzilla Cross Site Scripting and Security Bypass Vulnerabilities
|
Multiple vulnerabilities have been identified in Bugzilla, which could be exploited by attackers to bypass security restrictions or disclose certain information.
The first issue is caused by an error in the XML-RPC interface when creating bugs, which could be exploited by a user without "canconfirm" privileges to put bugs in the NEW or ASSIGNED state.
The second vulnerability is caused by an input validation error when using the "Format for Printing" or "Long Format" of a bug list, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected site.
The third weakness is caused by an error in the "email_in.pl" script that does not properly validate the "From" header, which could be exploited to bypass certain security checks.
