Mozilla Firefox 1.0.4 and 1.0.5 does not choose the challenge with the strongest authentication scheme available as required by RFC2617, which might cause credentials to be sent in plaintext even if an encrypted channel is available.

Security readout for executives and security teams

Older Mozilla Firefox versions could choose a weaker login method when a website offered multiple HTTP authentication options. In some cases, that could expose user credentials in plaintext even though a stronger option was available. Exposure is likely limited to organizations still running Firefox 1.0.4 or 1.0.5 against HTTP authentication endpoints that present multiple schemes. Modern supported browsers are not identified as affected in the supplied sources. Treat this as a legacy-browser credential exposure issue. It is not a broad modern emergency from the supplied evidence, but any remaining affected clients should be removed because exposed credentials can create disproportionate business risk. Mitigation focus: Retire Firefox 1.0.4 and 1.0.5 from enterprise use.; Check Mozilla guidance for fixed or supported replacement versions.; Disable or avoid plaintext HTTP authentication where business systems allow..
