An unauthenticated attacker can cause a denial-of-service to the following products: Ivanti Connect Secure (ICS) in versions prior to 9.1R14.3, 9.1R15.2, 9.1R16.2, and 22.2R4, Ivanti Policy Secure (IPS) in versions prior to 9.1R17 and 22.3R1, and Ivanti Neurons for Zero-Trust Access in versions prior to 22.3R1.

A use-after-free in Ivanti Connect Secure before version 22.7R2.3 and 9.1R18.9

and Ivanti Policy Secure before version 22.7R1.2 allows a remote authenticated attacker to achieve remote code execution

A vulnerability exists on all versions of Ivanti Connect Secure below 22.6R2 where an attacker can send a specific request which may lead to Denial of Service (DoS) of the appliance.

A heap overflow vulnerability in IPSec component of Ivanti Connect Secure (9.x 22.x) and Ivanti Policy Secure allows an unauthenticated malicious user to send specially crafted requests in-order-to crash the service thereby causing a DoS attack or in certain conditions read contents from memory.

A null pointer dereference vulnerability in IPSec component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure allows an unauthenticated malicious user to send specially crafted requests in-order-to crash the service thereby causing a DoS attack

An XML entity expansion or XEE vulnerability in SAML component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure allows an unauthenticated attacker to send specially crafted XML requests in-order-to temporarily cause resource exhaustion thereby resulting in a limited-time DoS.

A heap overflow vulnerability in IPSec component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure allows an unauthenticated malicious user to send specially crafted requests in-order-to crash the service thereby causing a DoS attack. In certain conditions this may lead to execution of arbitrary code

An unauthenticated attacker can cause a denial-of-service to the following products: Ivanti Connect Secure (ICS) in versions prior to 9.1R14.3, 9.1R15.2, 9.1R16.2, and 22.2R4, Ivanti Policy Secure (IPS) in versions prior to 9.1R17 and 22.3R1, and Ivanti Neurons for Zero-Trust Access in versions prior to 22.3R1.

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.

A vulnerability exists on all versions of Ivanti Connect Secure below 22.6R2 where an attacker impersonating an administrator may craft a specific web request which may lead to remote code execution.
