CVE-2004-0823: OpenLDAP 1.0 through 2.1.19, as used in Apple Mac OS 10.3.4 and 10.3.5 and possibly other operating systems...

OpenLDAP 1.0 through 2.1.19, as used in Apple Mac OS 10.3.4 and 10.3.5 and possibly other operating systems, may allow certain authentication schemes to use hashed (crypt) passwords in the userPassword attribute as if they were plaintext passwords, which allows remote attackers to re-use hashed passwords without decrypting them.

Security readout for executives and security teams

This old OpenLDAP flaw can turn a leaked password hash into a usable login secret. In affected configurations, some authentication schemes treated crypt hashes stored in userPassword like plaintext passwords, allowing reuse without cracking. Business urgency is highest for legacy LDAP systems still exposed to network authentication. Exposure is most likely in legacy OpenLDAP deployments at or below 2.1.19, especially old Apple Mac OS X 10.3.4/10.3.5 and vendor appliances or operating systems bundling OpenLDAP. Modern supported LDAP stacks are less likely exposed, but embedded legacy systems should be checked. Treat this as a legacy exposure risk. It is not KEV-listed in the provided bundle, but affected LDAP infrastructure can undermine authentication if old systems remain reachable or password hashes were exposed. Mitigation focus: Inventory and retire OpenLDAP 1.0 through 2.1.19 deployments.; Follow Apple, Red Hat, Avaya, or platform vendor advisories for supported fixes.; Restrict network access to legacy LDAP authentication services..
