Security researchers have unveiled a proof-of-concept (PoC) exploit for a critical remote code execution vulnerability in Ivanti Connect Secure, Policy Secure, and Neurons for ZTA gateways.
The vulnerability, tracked as CVE-2025-0282, has been assigned a CVSS score of 9.0, indicating its severe nature and potential impact on affected systems.
The flaw, described as a stack-based buffer overflow, affects Ivanti Connect Secure versions prior to 22.7R2.5, Ivanti Policy Secure versions before 22.7R1.2, and Ivanti Neurons for ZTA gateways earlier than version 22.7R2.3.
While the analysts at AttackerKB noted that this flaw can be exploited by remote unauthenticated attackers to achieve remote code execution on vulnerable systems and it makes this vulnerability particularly concerning.

MITRE ATT&CK Techniques
Cybersecurity experts have identified several MITRE ATT&CK techniques that could be leveraged by threat actors exploiting this vulnerability:-
- Initial Access (TA0001): Attackers could use this vulnerability as an entry point into target networks.
- Execution (TA0002): The ability to execute arbitrary code is a primary concern with this flaw.
- Privilege Escalation (TA0004): Successful exploitation could lead to elevated privileges on compromised systems.
The release of a PoC exploit significantly increases the risk of active exploitation in the wild.
Organizations using affected Ivanti products are strongly advised to apply the available patches immediately or implement recommended mitigations if patching is not immediately possible.
Ivanti has responded to the disclosure by releasing security updates to address the vulnerability. The company urges all customers to update their systems to the latest versions as soon as possible to mitigate the risk of potential attacks.
This development comes amid a broader trend of increasing attacks on VPN and remote access solutions, which have become critical infrastructure for many organizations in the era of remote work.
The MITRE ATT&CK framework has proven invaluable in understanding and defending against such threats, providing a common language for security teams to describe adversary tactics and techniques.
However, recent studies have highlighted challenges in effectively implementing these frameworks, emphasizing the need for continued education and refinement of security practices.
