| CVE | Description | CVSSv3 |
|---|---|---|
| CVE-2025-0282 | Ivanti Connect Secure, Ivanti Policy Secure and Ivanti Neurons for ZTA gateways Stack-based Buffer Overflow Vulnerability | 9.0 |
| CVE-2025-0283 | Ivanti Connect Secure, Ivanti Policy Secure and Ivanti Neurons for ZTA gateways Stack-based Buffer Overflow Vulnerability | 7.0 |
Analysis
CVE-2025-0282 is a stack-based buffer overflow vulnerability in Ivanti Connect Secure, Ivanti Policy Secure and Ivanti Neurons for ZTA gateways. An unauthenticated, remote attacker that successfully exploits this flaw would obtain remote code execution on a vulnerable device. CVE-2025-0283 is also a stack-based buffer overflow in Ivanti Connect Secure, Ivanti Policy Secure and Ivanti Neurons for ZTA gateways. Unlike CVE-2025-0282, a local, authenticated attacker that successfully exploits this flaw would be able to elevate privileges on a vulnerable device. In-the-wild exploitation observed for CVE-2025-0282 In a blog post, Ivanti confirmed that they have observed in-the-wild exploitation of CVE-2025-0282 in “a limited number of customers” of Ivanti Connect Secure devices. They reiterate that they have not observed exploitation against Ivanti Policy Secure or Neurons for ZTA gateways. Historical exploitation of Ivanti Connect Secure Ivanti Connect Secure, formerly known as Pulse Connect Secure, has been frequently targeted by attackers of all types, including advanced persistent threat (APT) groups as well as ransomware affiliates and opportunistic cybercriminals.
