A vulnerability exists in McAfee ASaP VirusScan that permits intruders to access files outside of the web root.
Quoting from the McAfee ASaP VirusScan FAQ, McAfee ASaP VirusScan is "a web-based, managed and updated anti-virus service for the entire desktop environment." McAfee ASaP VirusScan allows hosts to share virus definitions, eliminating the need for all of the hosts to update their virus signature software from one central location. In order to make this possible, each host running this software also runs a lightweight http server that listens on 6515/TCP. Because of a vulnerability that exists in this HTTP server, a malicious user can connect to 6515/TCP and traverse the host file system to access any file on the system. For example:
HTTP://<Target IP Address>:6515/.../.../.../.../winnt/repair
A malicious user can connect to 6515/TCP and traverse the host file system, thus viewing any file on the target host with the privileges of the HTTP server, typically SYSTEM.
NAI has patched this vulnerability. The patch will be automatically disseminated to all affected hosts. Quoting from an NAI announcement regarding this vulnerability:
This vulnerability was discovered by Aiden ORawe <firstname.lastname@example.org> and reported to the CERT Coordination Center.
