Pulse Secure version 9.115 and below may be susceptible to client-side http request smuggling, When the application receives a POST request, it ignores the request's Content-Length header and leaves the POST body on the TCP/TLS socket. This body ends up prefixing the next HTTP request sent down that connection, this means when someone loads website attacker may be able to make browser issue a POST to the application, enabling XSS.

In Ivanti Pulse Secure Pulse Connect Secure (PCS) before 9.1R12, the administrator password is stored in the HTML source code of the "Maintenance > Push Configuration > Targets > Target Name" targets.cgi screen. A read-only administrative user can escalate to a read-write administrative role.

A vulnerability in Pulse Connect Secure before 9.1R12.1 could allow an unauthenticated administrator to causes a denial of service when a malformed request is sent to the device.

A vulnerability in Pulse Connect Secure before 9.1R12 could allow an authenticated administrator to perform command injection via an unsanitized web parameter in the administrator web console.

A vulnerability in Pulse Connect Secure before 9.1R12 could allow an authenticated administrator to perform a file write via a maliciously crafted archive uploaded in the administrator web interface.

A vulnerability in Pulse Connect Secure before 9.1R12 could allow a threat actor to perform a cross-site script attack against an authenticated administrator via an unsanitized web parameter.

A vulnerability in Pulse Connect Secure before 9.1R12 could allow an authenticated administrator to perform command injection via an unsanitized web parameter.

A vulnerability in Pulse Connect Secure before 9.1R12 could allow an authenticated administrator or compromised Pulse Connect Secure device in a load-balanced configuration to perform a buffer overflow via a malicious crafted web request.

A vulnerability in Pulse Connect Secure before 9.1R12 could allow an authenticated administrator to perform an arbitrary file delete via a maliciously crafted web request.

A buffer overflow vulnerability exists in Windows File Resource Profiles in 9.X allows a remote authenticated user with privileges to browse SMB shares to execute arbitrary code as the root user. As of version 9.1R3, this permission is not enabled by default.

A vulnerability allowed multiple unrestricted uploads in Pulse Connect Secure before 9.1R11.4 that could lead to an authenticated administrator to perform a file write via a maliciously crafted archive upload in the administrator web interface.

A command injection vulnerability exists in Pulse Connect Secure before 9.1R11.4 allows a remote authenticated attacker to perform remote code execution via Windows Resource Profiles Feature

A buffer overflow vulnerability exists in Pulse Connect Secure before 9.1R11.4 allows a remote authenticated attacker to execute arbitrary code as the root user via maliciously crafted meeting room.

A vulnerability in the Pulse Connect Secure / Pulse Policy Secure below 9.1R9 could allow attackers to conduct Cross-Site Scripting (XSS) and Open Redirection for authenticated user web interface.

A vulnerability in the Pulse Connect Secure / Pulse Policy Secure < 9.1R9 is vulnerable to arbitrary cookie injection.

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 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.

XSS exists in the admin web console in Pulse Secure Pulse Connect Secure (PCS) 9.0RX before 9.0R3.4, 8.3RX before 8.3R7.1, and 8.1RX before 8.1R15.1 and Pulse Policy Secure 9.0RX before 9.0R3.2, 5.4RX before 5.4R7.1, and 5.2RX before 5.2R12.1.
