Format string vulnerability in the allowuser code for the Stellar-X msntauth authentication module, as distributed in Squid 2.4.STABLE6 and earlier, allows remote attackers to execute arbitrary code via format strings in the user name, which are not properly handled in a syslog call.

Security readout for executives and security teams

This is an old but serious bug in a Squid authentication helper. If an organization still runs Squid 2.4.STABLE6 or earlier with the Stellar-X msntauth module, a remote user name value could corrupt logging behavior and potentially lead to code execution. Exposure is likely limited to legacy Squid deployments using the Stellar-X msntauth authentication module. Modern or unsupported asset inventories may miss this if proxy infrastructure is old, embedded, or unmanaged. Prioritize if legacy Squid authentication infrastructure exists, especially on exposed proxy paths. Otherwise, this is mainly an inventory and legacy-risk cleanup issue. Mitigation focus: Identify Squid 2.4.STABLE6 or earlier systems using the msntauth module.; Review Squid vendor guidance and the referenced 2.4.STABLE6-to-2.4.STABLE7 changes.; Upgrade legacy Squid deployments to a supported, fixed release where feasible..
