Summary
by MITRE • 06/28/2024
Netwrix CoSoSys Endpoint Protector through 5.9.3 and CoSoSys Unify through 7.0.6 contain a remote code execution vulnerability in the Endpoint Protector and Unify agent in the way that the EasyLock dependency is acquired from the server. An attacker with administrative access to the Endpoint Protector or Unify server can cause a client to acquire and execute a malicious file resulting in remote code execution.

The vulnerability identified as CVE-2024-36074 represents a critical remote code execution flaw within the Netwrix CoSoSys Endpoint Protector and Unify products, affecting versions through 5.9.3 and 7.0.6 respectively. This vulnerability stems from how the EasyLock dependency is handled during the agent acquisition process, creating an exploitable condition that allows attackers to execute arbitrary code on targeted endpoints. The flaw specifically manifests in the server-side configuration where administrative privileges can be leveraged to manipulate the dependency delivery mechanism, ultimately enabling code execution on client systems that process these malicious dependencies.
The technical implementation of this vulnerability involves a privilege escalation scenario where administrative access to the server component directly translates to remote code execution capabilities on client endpoints. The EasyLock dependency mechanism serves as the attack vector, allowing an attacker to inject malicious code that gets executed when the client agent processes the dependency. This represents a classic case of insecure dependency handling and improper input validation within the software supply chain. The vulnerability aligns with CWE-494, which addresses the acquisition of a code component from an untrusted source, and demonstrates how trust relationships within enterprise security tools can be exploited to compromise entire networks. The flaw essentially allows an attacker to bypass traditional endpoint protection mechanisms by leveraging the legitimate dependency acquisition process.
From an operational impact perspective, this vulnerability presents a severe threat to enterprise security infrastructure as it allows attackers to gain full control over endpoints from a single administrative compromise. The attack chain begins with gaining administrative access to the server component, which then enables the attacker to manipulate the dependency delivery process and execute arbitrary code on all connected clients. This creates a potential for widespread system compromise across an organization's endpoint landscape, particularly in environments where these tools are deployed for security policy enforcement and endpoint protection. The vulnerability undermines the fundamental security assumptions of the software, as it allows attackers to execute code that bypasses the very security controls the software is designed to provide. Organizations using these products face the risk of complete system compromise, data exfiltration, and lateral movement within their networks, making this a critical concern for enterprise security teams.
Mitigation strategies for CVE-2024-36074 should prioritize immediate patching of affected versions, with administrators applying the vendor-provided security updates as soon as they become available. Network segmentation and access controls should be implemented to limit administrative access to the affected servers, reducing the attack surface for privilege escalation. Monitoring for unusual dependency acquisition patterns and implementing strict code signing policies can help detect potential exploitation attempts. The vulnerability demonstrates the importance of secure software supply chain practices and proper dependency management, aligning with ATT&CK technique T1195 which covers supply chain compromise. Organizations should also consider implementing endpoint detection and response solutions to monitor for suspicious code execution patterns and establish robust incident response procedures to address potential exploitation. Additionally, regular security assessments of critical infrastructure tools should be conducted to identify similar vulnerabilities in other enterprise security products that may present similar attack vectors.
