  Plain Text Password Vulnerability in Winamp
------------------------------------------------------------------------

SUMMARY

Winamp is a popular MP3 and other Audio codec's listening program, the
program ahs been found to contain a security vulnerability that would
allow a local attacker to gain username and password used for streaming
(and possibly used elsewhere) by reading Winamp's configuration file.

DETAILS

Vulnerable systems:
 * Winamp version 2.80

When a URL's is streamed in Winamp that requires HTTP authentication, the
user is prompted to enter a username and password. This username and
password is then stored as plain text in the file winamp.ini under the
section [HTTP-AUTH]. The format of stored passwords (it seems) is <domain
- TLD>=<username>:<password>.
 
URL's that are streamed are also kept as history in the winamp.ini file
under the [winamp] section. This includes URL's which include the
username/password in them (i.e. http://username:password@site).
