"The remote host is running Phpauction or one of its affiliate
versions, such as Web2035 Auction.  Phpauction is a web-based auction
system written in PHP. 

The version of Phpauction on the remote host suffers from multiple
flaws :

  - Remote Code Execution
    An attacker can control the 'lan' variable used to 
    include PHP code in the 'index.php' and 'admin/index.php'
    scripts, which may allow the viewing of arbitrary files 
    on the remote host and execution of arbitrary PHP code, 
    possibly even taken from third-party hosts.

  - Authentication Bypass
    By setting the cookie 'PHPAUCTION_RM_ID' to the id of an
    existing user, an attacker can bypass authentication.

  - SQL Injection
    The application does not properly sanitize user-supplied
    input to the 'category' parameter of the 'adsearch.php'
    script before using it in database queries.

  - Multiple Cross-Site Scripting Flaws
    The application fails to sanitize user-supplied input
    to several scripts before using it in dynamically-
    generated pages, which allows for cross-site scripting 
    attacks.");
