Title: Netscape Professional Services FTP Server Vulnerability
Severity: CRITICAL
Description:
Certain versions of the LDAP-aware Netscape Professional Services FTP Server (distributed with Enterprise Web Server) have a serious vulnerability which may lead to a remote or local root compromise. The vulnerability in essence is a failure of of the FTP server to enforce a restricted user environment (chroot). By failing to do this an FTP (anonymous or otherwise) user may download any file on the system (/etc/passwd etc.) as well as upload files at will at the privilege level of the FTP daemon.
Furthermore (quoted from the original attached message) this FTP server supports LDAP users; different LDAP accounts are served on single physical UID. This means, any user can access and eventually overwrite files on other accounts; as it's used in cooperation with webserver, typically virtual web servers are affected.
Affected Products:
- Netscape Professional Services FTP Server (LDAP Aware) 1.3.6
