CRITICAL:
Less critical

IMPACT:
Exposure of system information, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
Bugzilla 2.x
http://secunia.com/product/396/

DESCRIPTION:
Two security issues have been reported in Bugzilla, which can be
exploited by malicious people to disclose system and potentially
sensitive information.

1) The problem is that it is possible to access the "config.cgi"
script without being authenticated even when the "requirelogin"
parameter setting is enabled. This can be exploited to disclose
certain product information (e.g. product names).

The security issue has been reported in versions 2.18rc1 through
2.18.3, 2.19 through 2.20rc2, and 2.21.

2) The problem is that it is possible to list invisible users when
using the user matching feature when the "usevisibilitygroups"
parameter setting is enabled.

Successful exploitation requires that user matching is enabled in
"substring" mode.

The security issue has been reported in versions 2.19.1 through
2.20rc2, and 2.21.

SOLUTION:
Update to 2.18.4, 2.20, or 2.21.1.
