Title: Bugzilla showattachment.cgi Arbitrary Bug Viewing Vulnerability

Severity: HIGH

Description:

Bugzilla is a free, open source bug tracking and reporting appplication. It allows users to submit bugs, offers a forum for discussing bugs, keeps track of the status of bugs, and can restrict who has access to bug information.

An input validation problem exists with Bugzilla. A user of Bugzilla may submit an arbitrary bug ID number as an argument to 'showattachment.cgi', potentially disclosing information about "restricted" bugs. The arbitrary bug ID is included as part of an HTTP request, example:

http://bugzillahost/showattachment.cgi?id=XXXXX

This may be a threat if Bugzilla is being used during the development of proprietary sourcecode.

Affected Products:

  • Mozilla Bugzilla 2.10.0
  • Mozilla Bugzilla 2.12.0
  • Mozilla Bugzilla 2.4.0
  • Mozilla Bugzilla 2.6.0
  • Mozilla Bugzilla 2.8.0
