written in PHP.

There are multiple input validation flaws in the remote version of this
software :

  - There is a SQL injection vulnerability in the file 
    'redir_url.php' that could allow an attacker to execute 
    arbitrary SQL statements in the remote database ;

  - There is a cross-site scripting issue that could allow 
    an attacker to steal the cookies of the legitimate users 
    of the remote site by sending them a specially malformed 
    link ;

  - There is an HTTP response splitting vulnerability that 
    could allow an attacker to perform cross-site scripting 
    attacks against the remote host."
