CVSS v3.1
Official Description
iPlanet Web Server Enterprise Edition 4.1 and earlier allows remote attackers to retrieve sensitive data from memory allocation pools, or cause a denial of service, via a URL-encoded Host: header in the HTTP request, which reveals memory in the Location: header that is returned by the server.
Technical Analysis
CVE-2001-0327 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
