CVE-2003-0881: Mail in Mac OS X before 10.3, when configured to use MD5 Challenge Response, uses plaintext authentication...

Mail in Mac OS X before 10.3, when configured to use MD5 Challenge Response, uses plaintext authentication if the CRAM-MD5 hashed login fails, which could allow remote attackers to gain privileges by sniffing the password.

Security readout for executives and security teams

Older Apple Mail clients on Mac OS X before 10.3 could fall back to sending a password in plaintext after a failed CRAM-MD5 login. An attacker with network visibility could capture that password and use it to access the user’s mail account or related services. Exposure is likely limited to legacy Mac OS X Mail deployments before 10.3 using MD5 Challenge Response. Modern supported macOS environments are unlikely to be affected, but archived systems, labs, or unmanaged legacy endpoints should be checked. Treat this as a legacy hygiene issue unless vulnerable systems are still present. If old Mac OS X Mail clients remain on business networks, prioritize retirement because the flaw can expose reusable passwords. Mitigation focus: Identify and retire Mac OS X Mail clients before 10.3.; Upgrade affected systems to Mac OS X 10.3 or later per Apple guidance.; Check Apple’s advisories for any environment-specific remediation details..
