CVE-2008-5015: Mozilla Firefox

Medium severity, CVSS 5.1. EPSS: 2.2% chance of exploitation in the next 30 days.

Mozilla Firefox 3.x before 3.0.4 assigns chrome privileges to a file: URI when it is accessed in the same tab from a chrome or privileged about: page, which makes it easier for user-assisted attackers to execute arbitrary JavaScript with chrome privileges via malicious code in a file that has already been saved on the local system.

Affected products

• Mozilla Firefox: up to and including 3.0.3; version 3.0 only; version 3.0.1 only; version 3.0.2 only
