  PGP Keyserver's Inadequate Permissions
------------------------------------------------------------------------

SUMMARY

PGP Keyserver, distributed by Network Associates, suffers from a
vulnerability that allows attackers to access administrative web interface
without authentication.

DETAILS

Vulnerable systems:
PGP Keyserver 7.0 for Windows NT

PGP Keyserver, distributed by Network Associates, is configured using
administrative web interface. It is necessary to authenticate username and
password in order to access the administrative web interface.

However, PGP Keyserver has a vulnerability that allows unauthorized users
to change settings. Normally, changes of configuration via authentication
occur in the following URL:

http://server.name/keyserver/cgi-bin/console.exe?page_size=...
http://server.name/keyserver/cgi-bin/cs.exe?action=...

PGP Keyserver allows attackers to perform administrative tasks without
authentication by using the following URL:

http://server.name/cgi-bin/console.exe?page_size=...
http://server.name/cgi-bin/cs.exe?action=...
