CVE-2025-0282 is a critical security vulnerability that affects Ivanti Connect Secure, Policy Secure, and Neurons for ZTA gateways. This vulnerability is a stack-based buffer overflow that allows a remote unauthenticated attacker to potentially achieve remote code execution on the targeted network devices. This post details the affected software, exploitation details, code snippets, and useful resources for addressing the issue.

Exploit Details

The root cause of the vulnerability lies in improper handling of a specific input parameter within the affected software components. An unauthenticated remote attacker can exploit this vulnerability by crafting a malicious input, which causes a buffer overflow on the software stack, thus leading to execution of arbitrary code on the targeted system. The following is a simplified version of the malicious input that could be used by an attacker to exploit the vulnerability:

#include <stdio.h>
#include <string.h>

// Malicious input function
void crafted_input() {
  char buffer[64];
  memset(buffer, 'A', 128); // Overwriting the buffer with 128 'A' characters
}

int main() {
  crafted_input();
  return ;
}

Mitigation

Ivanti has released software updates to mitigate this vulnerability. Administrators should update their software to the following versions:

Software updates can be obtained from Ivanti's support website

1. Ivanti Connect Secure Update 22.7R2.5
2. Ivanti Policy Secure Update 22.7R1.2
3. Ivanti Neurons for ZTA gateways Update 22.7R2.3

In addition to updating the software, administrators should also ensure that they are applying best practices in network security, such as:

Conclusion

CVE-2025-0282 is a critical vulnerability that affects multiple Ivanti products. If left unpatched, it allows a remote unauthenticated attacker to execute arbitrary code on the targeted system. To prevent exploitation, administrators should update their Ivanti software to the latest versions and ensure that proper network security practices are in place.
