The installation confirmation dialog in Firefox before 1.0.1, Thunderbird before 1.0.1, and Mozilla before 1.7.6 allows remote attackers to use InstallTrigger to spoof the hostname of the host performing the installation via a long "user:pass" sequence in the URL, which appears before the real hostname.

Security readout for executives and security teams

This 2005 issue could make an old Mozilla installation prompt show a misleading host name. A user might think software came from a trusted site when the real source was different. The risk is mainly legacy systems running very old Firefox, Thunderbird, or Mozilla Suite versions. Exposure is likely limited to obsolete or unmanaged systems still running affected Mozilla-era clients. Modern supported Firefox and Thunderbird versions are not identified as affected in the provided sources. Treat this as a legacy-risk cleanup item unless affected software is still deployed. It is not KEV-listed in the provided data, but obsolete clients can increase phishing and unsafe software installation risk. Mitigation focus: Upgrade Firefox to 1.0.1 or later where legacy use remains.; Upgrade Thunderbird to 1.0.1 or later where legacy use remains.; Upgrade Mozilla Suite to 1.7.6 or later where present..
