Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, when the XMLHttpRequestSpy module in the Firebug add-on is used, does not properly handle interaction between the XMLHttpRequestSpy object and chrome privileged objects, which allows remote attackers to execute arbitrary JavaScript via a crafted HTTP response. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-0179.

Security readout for executives and security teams

This vulnerability affected obsolete Mozilla Firefox and SeaMonkey versions when the Firebug add-on's XMLHttpRequestSpy feature was used. A malicious HTTP response could trigger arbitrary JavaScript execution through mishandled privileged browser objects. Business urgency is mainly for legacy systems, archived images, kiosks, or appliances still running those old browsers or vendor packages. Exposure is unlikely in normal modern desktops, but plausible in unmanaged legacy hosts, frozen virtual machines, embedded/admin workstations, or third-party products bundling old Mozilla components plus Firebug. The bundled affected data is incomplete and lists generic vendor/product values, so asset validation is essential. Treat as a legacy exposure cleanup item with high impact if found. It should not distract from current exploited vulnerabilities unless old Mozilla browsers or bundled components are present in business-critical environments. Mitigation focus: Upgrade Firefox to 3.5.16, 3.6.13, or later supported versions.; Upgrade SeaMonkey to 2.0.11 or later supported versions.; Remove or disable Firebug on legacy browser installations where upgrade is delayed..
