Published: Translated: NVD NIST

Summary

Vulnerability in squid_ldap_auth in Squid 2.5 and earlier allows remote authenticated users to bypass username-based Access Control Lists (ACLs) via a username with a space at the beginning or end, which is ignored by the LDAP server.

Risk Assessment

The organization is at risk of unauthorized access to resources protected by ACLs, as an attacker can use a username with spaces to bypass access controls.

Recommendation

Update Squid to a version later than 2.5, which includes a fix that strips spaces from usernames before processing by LDAP.
