Title: Bugzilla Remote Arbitrary Command Execution Vulnerability
Severity: HIGH
Description:
Bugzilla is a web-based bug-tracking system based on Perl and MySQL. It allows people to submit bugs and catalogs them.
Bugzilla is prone to a vulnerability which may allow remote users to execute arbitrary commands on the target webserver.
Consequently, commands can be appended to the end of the form values and executed by /bin/sh in the manner: "value;id". The form value that is passed to system() for all bug reports is "who", shown here in this section of code from "process_bug.cgi":
system("./processmail $k $::FORM{'who'}");
What this means is that it is possible for an attacker to supply maliciously crafted input to form fields, which when submitted will cause arbitrary commands to be executed on the shell of the host running vulnerable versions of Bugzilla. Commands will be executed with the privileges of the webserver process.
Affected Products:
- Mozilla Bugzilla 2.10.0
- Mozilla Bugzilla 2.4.0
- Mozilla Bugzilla 2.6.0
- Mozilla Bugzilla 2.8.0
