CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

iPlanet Web Server Enterprise Edition and Netscape Enterprise Server 4.0 and 4.1 allows remote attackers to conduct HTTP Basic Authentication via the wp-force-auth Web Publisher command, which provides a distinct attack vector and may make it easier to conduct brute force password guessing without detection.

The weakness was shared 12/31/2002 by Richard Brain with ProCheckUp as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is uniquely identified as CVE-2002-1654 since 03/29/2005. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

The commercial vulnerability scanner Qualys is able to test this issue with plugin 86304 (Netscape Enterprise Server Brute Force Authentication Attacks Vulnerability).
