A denial of service vulnerability exists in Pulse Connect Secure <9.1R8 that allows an authenticated attacker to perform command injection via the administrator web which can cause DOS.

An insufficient permission check vulnerability exists in Pulse Connect Secure <9.1R8 that allows an attacker to change the password of a full administrator.

A code injection vulnerability exists in Pulse Connect Secure <9.1R8 that allows an attacker to crafted a URI to perform an arbitrary code execution via the admin web interface.

A cross site scripting (XSS) vulnerability in Pulse Connect Secure <9.1R8 allowed attackers to exploit in the URL used for Citrix ICA.

An information disclosure vulnerability in meeting of Pulse Connect Secure <9.1R8 allowed an authenticated end-users to find meeting details, if they know the Meeting ID.

An improper authentication vulnerability exists in Pulse Connect Secure <9.1RB that allows an attacker with a users primary credentials to bypass the Google TOTP.

A cross site scripting (XSS) vulnerability exists in Pulse Connect Secure <9.1R5 on the PSAL Page.

An issue was discovered in Pulse Secure Pulse Connect Secure before 9.1R8. An authenticated attacker can access the admin page console via the end-user web interface because of a rewrite.

An issue was discovered in Pulse Policy Secure (PPS) and Pulse Connect Secure (PCS) Virtual Appliance before 9.1R8. By manipulating a certain kernel boot parameter, it can be tricked into dropping into a root shell in a pre-install phase where the entire source code of the appliance is available and can be retrieved. (The source code is otherwise inaccessible because the appliance has its hard disks encrypted, and no root shell is available during normal operation.)

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. This can be reached by local HTTP clients, because up to 25 invalid lines are ignored, and because DNS rebinding can occur. (This server accepts, for example, a setcookie command that might be relevant to CVE-2020-11581 exploitation.)

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, allows a man-in-the-middle attacker to perform OS command injection attacks (against a client) via shell metacharacters to the doCustomRemediateInstructions method, because Runtime.getRuntime().exec() is used.

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, accepts an arbitrary SSL certificate.

Pulse Secure Pulse Connect Secure 8.1.x before 8.1R14, 8.2.x before 8.2R11, and 8.3.x before 8.3R5 do not properly process nested XML entities, which allows remote attackers to cause a denial of service (memory consumption and memory errors) via a crafted XML document.

A cross site scripting issue has been found in custompage.cgi in Pulse Secure Pulse Connect Secure (PCS) before 8.0R17.0, 8.1.x before 8.1R13, 8.2.x before 8.2R9, and 8.3.x before 8.3R3 and Pulse Policy Secure (PPS) before 5.2R10, 5.3.x before 5.3R9, and 5.4.x before 5.4R3 due to one of the URL parameters not being sanitized. Exploitation does require the user to be logged in as administrator; the issue is not applicable to the end user portal.
