Vulnerability in Mozilla Firefox

CVE-2009-1306

The jar: URI implementation in Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey does not follow the Content-Disposition header of the inner URI, which allows remote attackers to conduct cross-site scripting (XSS) attacks and possibly other attacks via an uploaded .jar file with a "Content-Disposition: attachment" designation.

EPSS: 0.013 (68.1th percentile) — read the EPSS interpretation.
