Mozilla Firefox 1.5.x before 1.5.0.12 and 2.x before 2.0.0.4, and SeaMonkey 1.0.9 and 1.1.2, allows remote attackers to bypass the same-origin policy and conduct cross-site scripting (XSS) and other attacks by using the addEventListener method to add an event listener for a site, which is executed in the context of that site.

Security readout for executives and security teams

This is an old browser same-origin policy bypass in Mozilla Firefox and SeaMonkey. A malicious web page could make injected event handling run as if it belonged to another site, enabling cross-site scripting-style abuse. The business risk today is mainly from unmanaged legacy systems or embedded desktop images still running affected browser builds. Exposure is likely limited to legacy endpoints, old Linux/Unix distributions, archived virtual machines, or appliance images using the affected Mozilla browser packages. Modern supported Firefox and SeaMonkey builds are not identified as affected in the provided sources. Low immediate priority for modern environments, but worth closing during legacy endpoint cleanup. Prioritize any internet-browsing hosts, kiosk systems, administrative workstations, or old server desktops where affected browsers may still be present. Mitigation focus: Upgrade Firefox to 1.5.0.12, 2.0.0.4, or a supported later release.; Upgrade SeaMonkey using the relevant Mozilla or operating-system vendor advisory.; Remove affected legacy browsers from managed endpoint images and jump hosts..
