CVE-2005-3532

High
Published: Translated: NVD NIST

Summary

Vulnerability in Courier Mail Server 0.37.3–0.52.1 in the authpam.c file of the courier-authdaemon component. When pam_tally is used, the pam_acct_mgmt function is not called to verify that access should be granted. This allows attackers to authenticate to the server using accounts that have been disabled.

Risk Assessment

The risk is the possibility of bypassing the account locking mechanism (e.g., after multiple failed login attempts), enabling unauthorized access to the mail server using disabled accounts.

Recommendation

Update Courier Mail Server to a version later than 0.52.1 where the issue is fixed. If an update is not possible, consider temporarily disabling pam_tally or using another account locking mechanism.
