The map_yp_alias function in functions/imap_general.php in SquirrelMail before 1.4.19-1 on Debian GNU/Linux, and possibly other operating systems and versions, allows remote attackers to execute arbitrary commands via shell metacharacters in a username string that is used by the ypmatch program. NOTE: this issue exists because of an incomplete fix for CVE-2009-1579.

Security readout for executives and security teams

This flaw lets a remote user feed dangerous characters in a username to SquirrelMail on affected systems, potentially causing the server to run unintended operating-system commands. The clearest exposure is Debian SquirrelMail before 1.4.19-1; the CVE notes other platforms or versions may also be affected. Internet-facing or user-accessible SquirrelMail deployments are the main concern, especially Debian GNU/Linux systems running SquirrelMail before 1.4.19-1. Exposure may depend on use of the affected YP/NIS alias lookup path. Prioritize remediation if SquirrelMail is still deployed. Although old, this is remote command execution in a mail-facing application, and legacy webmail often remains exposed long after support expectations fade. Mitigation focus: Upgrade SquirrelMail using the relevant Debian, Fedora, or Mandriva security advisory packages.; For Debian, ensure SquirrelMail is not older than the fixed 1.4.19-1 referenced by the CVE.; Check vendor guidance for any supported workaround if immediate patching is not possible..
