• Description
  XSS vulnerabilities have been found within HP System Management; Arising from insufficient input filtering.
  By using a specially-crafted link, and tricking the victim into clicking on it, an attacker can perform malicious attacks such as the following:
  
  - Hijack user accounts by stealing the victim's cookies that are assigned to the victim's browser by the vulnerable website
  
  - Hijack user accounts by injecting a "fake" html form on the html rendered by the victim's web browser
  
  - Redirect the victim to a malicious third-party website which would perform a phishing attack to steal the user credentials or exploit a vulnerability (i.e.: buffer overflow) on the victim's web browser in order to compromise the victim's workstation
  
  Notes:
  
  Authentication is normally needed, unless system has been configured to support anonymous autologin.
