CVE-2012-3992: n/a vulnerability

CVE-2012-3992: Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x...

Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, and SeaMonkey before 2.13 do not properly manage history data, which allows remote attackers to conduct cross-site scripting (XSS) attacks or obtain sensitive POST content via vectors involving a location.hash write operation and history navigation that triggers the loading of a URL into the history object.

Security readout for executives and security teams

This is a legacy Mozilla browser and mail-client vulnerability. A malicious web page could abuse history handling to run cross-site scripting or expose sensitive POST content. The main business risk is from unmanaged or embedded old Mozilla products, not current supported deployments. Exposure is most likely in legacy desktops, old Linux packages, frozen virtual images, kiosk systems, or embedded workflows still using affected Mozilla versions. Current supported browser and mail-client installations should not be assumed affected from these sources alone. Treat this as a legacy exposure cleanup item. Prioritize any affected systems that browse the internet, process external email, or operate in shared user environments. It is not KEV-listed in the provided data, so urgency depends on whether affected versions still exist internally. Mitigation focus: Upgrade Firefox, Thunderbird, ESR builds, and SeaMonkey to fixed or supported versions.; Use vendor package advisories for Red Hat, Ubuntu, SUSE, Mandriva, or Mozilla-managed deployments.; Remove unsupported legacy Mozilla applications where upgrade is not possible..
