medium Nessus Network Monitor Plugin ID 9988
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host is running a version of Bugzilla which is affected by multiple cross-site scripting (XSS) attack vectors.

Description

According to its banner, the version of Bugzilla running on the remote host is 4.4.x prior to 4.4.12, or 5.0.x prior to 5.0.3. These versions are affected by the following vulnerabilities :

- A flaw exists that allows a stored cross-site scripting (XSS) attack. This flaw exists because the 'showdependencygraph.cgi' script does not validate input to bug summaries before returning it to users. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
- A flaw exists that allows a XSS attack. This flaw exists because the 'template/en/default/global/tabs.html.tmpl' script does not validate input to 'tab.link' before returning it to users. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.

Solution

Upgrade to version 5.0.3. If 5.0.x cannot be obtained, 4.4.12 has also been patched for these vulnerabilities.
