CVE-2001-0327 describes a vulnerability in iPlanet Web Server Enterprise Edition 4.1 and earlier, allowing remote attackers to extract sensitive memory data or trigger a denial of service. This is achieved by sending a specially crafted, URL-encoded Host header in an HTTP request, which causes the server to reveal memory contents within its Location header. Rated as Medium severity (CVSS 5.0), it requires no authentication and has low attack complexity, but only impacts confidentiality. There is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and it is not on the KEV catalog, though it has garnered significant community discussion.
