1. Description  
  
Certain Secure Access SA Series SSL VPN products (originally developed by  
Juniper Networks but now sold and supported by Pulse Secure, LLC) allow  
privilege escalation, as demonstrated by Secure Access SSL VPN SA-4000  
5.1R5 (build 9627) 4.2 Release (build 7631). This occurs because  
appropriate controls are not performed.  
  
  
2. Proof of Concept  
  
It is possible to change the administrator user password from readonly user  
because the appropriate controls are not performed. Save the page  
/dana-admin/user/update.cgi in local, change the "user" value and save  
changes.  
  
  
3. Solution:  
  
This version is deprecated. Update to last version this product.
