CVE-2012-5623: Squirrelmail 4.0 uses the outdated MD5 hash algorithm for passwords.

Security readout for executives and security teams

Squirrelmail 4.0 reportedly stores or handles passwords using MD5, an obsolete hash algorithm. This mainly increases risk after password hashes are exposed, because MD5 is fast to crack. The sources do not show active exploitation or a direct remote compromise path. Exposure is limited to environments running Squirrelmail 4.0, based on the supplied affected-product data. Risk is higher where password hashes, backups, logs, or databases could be accessed by attackers or insiders. Prioritize discovery and remediation planning if Squirrelmail 4.0 is present. This is most urgent where credential stores may be exposed or where users reuse passwords across business systems. Mitigation focus: Inventory systems for Squirrelmail 4.0 deployments.; Check Squirrelmail or distributor guidance for supported fixes or migration paths.; Move away from MD5 password storage where vendor-supported options exist..
