A Bugzilla Security Advisory reports:

The login form had no CSRF protection, meaning that an attacker could force the victim to log in using the attacker's credentials. If the victim then reports a new security sensitive bug, the attacker would get immediate access to this bug.

Due to changes involved in the Bugzilla API, this fix is not backported to the 4.0 and 4.2 branches, meaning that Bugzilla 4.0.12 and older, and 4.2.8 and older, will remain vulnerable to this issue.

A Bugzilla Security Advisory reports:

Dangerous control characters can be inserted into Bugzilla, notably into bug comments. If the text, which may look safe, is copied into a terminal such as xterm or gnome-terminal, then unexpected commands could be executed on the local machine.

Bugzilla Security Advisory

A CSRF vulnerability in report.cgi would allow a third-party site to extract confidential information from a bug the victim had access to.

< 5.0.4

Bugzilla Security Advisory

Login names (usually an email address) longer than 127 characters are silently truncated in MySQL which could cause the domain name of the email address to be corrupted. An attacker could use this vulnerability to create an account with an email address different from the one originally requested. The login name could then be automatically added to groups based on the group's regular expression setting.

< 4.4.10

< 5.0.1

Bugzilla Security Advisory

A specially crafted bug summary could trigger XSS in dependency graphs. Due to an incorrect parsing of the image map generated by the dot script, a specially crafted bug summary could trigger XSS in dependency graphs.

Bugzilla Security Advisory

Command Injection

Some code in Bugzilla does not properly utilize 3 arguments form for open() and it is possible for an account with editcomponents permissions to inject commands into product names and other attributes.

Information Leak

Using the WebServices API, a user can possibly execute imported functions from other non-WebService modules. A whitelist has now been added that lists explicit methods that can be executed via the API.

< 4.4.7

Bugzilla Security Advisory

Unauthorized Account Creation

An attacker creating a new Bugzilla account can override certain parameters when finalizing the account creation that can lead to the user being created with a different email address than originally requested. The overridden login name could be automatically added to groups based on the group's regular expression setting.

Cross-Site Scripting

During an audit of the Bugzilla code base, several places were found where cross-site scripting exploits could occur which could allow an attacker to access sensitive information.

Information Leak

If a new comment was marked private to the insider group, and a flag was set in the same transaction, the comment would be visible to flag recipients even if they were not in the insider group.

Social Engineering

Search results can be exported as a CSV file which can then be imported into external spreadsheet programs. Specially formatted field values can be interpreted as formulas which can be executed and used to attack a user's computer.

< 4.4.6

Bugzilla Security Advisory

During the generation of a dependency graph, the code for the HTML image map is generated locally if a local dot installation is used. With escaped HTML characters in a bug summary, it is possible to inject unfiltered HTML code in the map file which the CreateImagemap function generates. This could be used for a cross-site scripting attack.

If an external HTML page contains a
