This vulnerability has a CVSS 3.0 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical 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. Specifically, it is possible for a readonly user to change the administrator user password by making a local copy of the /dana-admin/user/update.cgi page, changing the "user" value, and saving the changes.
Remediation
Check the references section for vendor advisories and patches from pulsesecure. Update secure_access_series_ssl_vpn_sa-4000 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
