Clearswift MAILsweeper for SMTP 4.3.6 SP1 does not execute custom "on strip unsuccessful" hooks, which allows remote attackers to bypass e-mail attachment filtering policies via an attachment that MAILsweeper can detect but not remove.

Security readout for executives and security teams

This issue affects an old Clearswift MAILsweeper for SMTP release where a configured safety action may not run after attachment removal fails. An attacker could send an attachment that the gateway detects but cannot strip, bypassing an email attachment filtering policy. Exposure appears limited to organizations still using Clearswift MAILsweeper for SMTP 4.3.6 SP1 with custom hooks or policies that depend on strip-failure handling. Treat as urgent only if this legacy mail gateway version is still in production. The main risk is silent failure of an email control executives may assume is enforcing attachment policy. Mitigation focus: Check Clearswift or successor vendor guidance for the relevant MAILsweeper patch or upgrade path.; Inventory and retire unsupported MAILsweeper deployments where possible.; Review policies that rely on custom strip-failure hooks..
