CVE-2020-11582
Pulse Connect Secure Applet Host Checker TCP Server Remote Command Execution Vulnerability
Description
An issue was discovered in Pulse Secure Pulse Connect Secure (PCS) through 2020-04-06. The applet in tncc.jar, executed on macOS, Linux, and Solaris clients when a Host Checker policy is enforced, launches a TCP server that accepts local connections on a random port.
