Pulse Secure Virtual Traffic Manager 9.9 versions prior to 9.9r2 and 10.4r1 allow a remote authenticated user to obtain sensitive historical activity information by leveraging incorrect permission validation.
Technical Analysis
CVE-2018-20307 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
