  • Project: Joomla!
  • SubProject: Multiple
  • Severity: Low
  • Versions: 1.5.6 and all previous 1.5 releases
  • Exploit type: Redirect Spam 
  • Reported Date: 2008-August-26 
  • Fixed Date: 2008-September-9

Description

Several components utilize a passed in URL to redirect to after processing.  These URLs are not validated prior to the redirect.  A crafted URL can cause the system to redirect to a spam or phishing site.

3PD Concerns

3pd extensions should validate all redirects (where the URL cannot be trusted) using the new JURI method isInternal($url).  JURI::isInternal($url) will return true if the passed in url is a url on the same host as Joomla, or false if it is not.  JURI::isInternal($url) was not available prior to 1.5.7.

Affected Installs

All 1.5.x installs prior to and including 1.5.6 are affected.

Solution

Upgrade to latest Joomla! version (1.5.7 or newer).

  • Severity: Critical
  • Versions: 1.5.6 and all previous 1.5 releases
  • Exploit type: Variable Injection 
  • Reported Date: 2008-September-7 
  • Fixed Date: 2008-September-9

Description

A flaw in JRequest exists where variables set with JRequest::setVar are not cleaned when fetching the variable at a later point in the request.  This can result in variable injection (unwanted characters injected into returned data).

3PD Concerns

3PD extensions which use JRequest do not need to change anything for proper function.

Affected Installs

All 1.5.x installs prior to and including 1.5.6 are affected.

Solution

Upgrade to latest Joomla! version (1.5.7 or newer).
