CVE-2008-5507: n/a vulnerability

CVE-2008-5507: Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19, Thunderbird 2.x before 2.0.0.19, and SeaMonkey 1....

Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19, Thunderbird 2.x before 2.0.0.19, and SeaMonkey 1.x before 1.1.14 allow remote attackers to bypass the same origin policy and access portions of data from another domain via a JavaScript URL that redirects to the target resource, which generates an error if the target data does not have JavaScript syntax, which can be accessed using the window.onerror DOM API.

Security readout for executives and security teams

CVE-2008-5507 is a cross-domain data exposure flaw in old Mozilla clients. A malicious webpage could bypass browser same-origin protections and read portions of data from another site. The named affected products are Firefox, Thunderbird, and SeaMonkey versions released before the listed fixed releases. Exposure is most likely in legacy environments still running Firefox before 3.0.5 or 2.0.0.19, Thunderbird before 2.0.0.19, or SeaMonkey before 1.1.14. Modern supported browsers are unlikely to be affected by this specific historical issue. Low for most organizations today, but moderate where legacy browsers or mail clients still touch sensitive web applications. Prioritize confirmation during legacy asset reviews rather than emergency response. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the fixed versions listed by Mozilla and distro advisories.; Remove unsupported Mozilla clients from managed endpoints and golden images.; Block legacy browsers from accessing sensitive internal or authenticated web applications..
