Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 allows user-assisted remote attackers to inject arbitrary web script or HTML via a selection that is added to a document in which the designMode property is enabled.

Security readout for executives and security teams

This is a 2010 user-assisted cross-site scripting issue in older Mozilla Firefox, Thunderbird, and SeaMonkey releases. A victim would need to interact with a crafted selection added into a designMode-enabled document. The main business risk today is forgotten legacy software or vendor-packaged Mozilla components still present in managed environments. Exposure is most likely where legacy Mozilla applications, old Linux distribution packages, or vendor-bundled Mozilla components remain installed. Modern environments using supported browser and mail-client versions are unlikely to be affected, but the provided sources do not enumerate every downstream product. Handle as a legacy exposure cleanup item unless vulnerable versions are still deployed. If found on systems handling external web or email content, prioritize removal or upgrade because XSS can support credential theft or session abuse in the affected application context. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the affected versions listed in the CVE.; Remove obsolete Mozilla applications where business use no longer exists.; Check OS vendor advisories for patched downstream packages..
