CVE-2018-20193: Pulse Secure Secure Access Series SSL VPN Sa-4000

High severity, CVSS 8.8. EPSS: 1.3% chance of exploitation in the next 30 days.

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.

Affected products

• Pulse Secure Secure Access Series SSL VPN Sa-4000: version 4.2 only; version 5.1r5 only
