Description:
Some vulnerabilities and a security issue have been reported in Bugzilla, which can be exploited by malicious users to inject shell commands, and by malicious people to conduct cross-site scripting attacks and to disclose potentially sensitive information.
1) Input passed to the "buildid" parameter when filing bugs using the guided form is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability is reported in version 2.17.1 and later.
2) The "Email::Send::Sendmail()" function does not properly sanitise Bugzilla's "from" email information which is later passed to the "-f" parameter of sendmail. This can be exploited to inject shell commands via a specially crafted "from" setting.
The vulnerability is reported in version 2.23.4 and later.
3) The XML-RPC interface of Bugzilla allows to disclose certain time-tracking information without proper access to the time-tracking fields.
The security issue is reported in version 2.23.3 and above.
Solution:
Update to a fixed version.
Bugzilla 2.20.x users:
Update to version 2.20.5.
Bugzilla 2.22.x users:
Update to version 2.22.3.
Bugzilla 3.0 users:
Update to version 3.0.1.
