Squid 2.5, when processing the configuration file, parses empty Access Control Lists (ACLs), including proxy_auth ACLs without defined auth schemes, in a way that effectively removes arguments, which could allow remote attackers to bypass intended ACLs if the administrator ignores the parser warnings.

Security readout for executives and security teams

This is an old Squid 2.5 access-control parsing flaw. If an administrator left empty ACL entries in the configuration and ignored Squid parser warnings, intended proxy restrictions could be weakened, letting remote users bypass policy. The source bundle does not show active exploitation or a CVSS score. Likely limited to legacy Squid 2.5 systems or old appliances based on it. Exposure is most relevant where Squid enforces authentication or network access policy and configuration files contain empty ACL definitions. Handle during legacy infrastructure review unless Squid 2.5 still protects sensitive proxy access. Internet-facing or authentication-enforcing deployments should be prioritized because the weakness affects policy enforcement. Mitigation focus: Inventory Squid 2.5 deployments and distribution packages.; Apply the relevant Squid or distribution security update.; Review squid.conf for empty ACL definitions, especially proxy_auth entries..
