CVE-2025-57624 is a high-severity DLL hijacking vulnerability affecting CYRISMA Agent versions prior to build 444. DLL hijacking occurs when an application loads a malicious Dynamic Link Library (DLL) instead of the legitimate one, typically due to insecure search order or improper validation of DLL paths. In this case, local users with limited privileges can exploit this vulnerability by placing specially crafted DLL files in locations where the CYRISMA Agent will load them, thereby escalating their privileges and executing arbitrary code with higher system rights. The vulnerability is classified under CWE-427 (Uncontrolled Search Path Element), indicating that the software does not securely control the paths from which DLLs are loaded. The CVSS v3.1 base score of 7.8 reflects a high severity, with the vector indicating that the attack requires local access (AV:L), low attack complexity (AC:L), low privileges (PR:L), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H). No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that mitigation may require vendor updates or workarounds. This vulnerability allows an attacker to gain elevated privileges on the affected system, potentially leading to full system compromise, data theft, or disruption of services.

For European organizations, the impact of CVE-2025-57624 can be significant, especially in environments where CYRISMA Agent is deployed for endpoint management or security monitoring. Successful exploitation enables local attackers to escalate privileges, bypassing security controls and potentially gaining administrative access. This can lead to unauthorized access to sensitive data, disruption of critical services, and the ability to deploy further malware or ransomware. Given the high confidentiality, integrity, and availability impact, organizations could face operational downtime, data breaches, and regulatory non-compliance issues under GDPR if personal data is compromised. The lack of user interaction requirement means that once an attacker has local access, exploitation can be automated and stealthy. This is particularly concerning for organizations with shared workstations, remote desktop access, or insider threat risks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers often develop exploits rapidly after public disclosure.

To mitigate CVE-2025-57624 effectively, European organizations should: 1) Immediately inventory all systems running CYRISMA Agent and identify versions prior to build 444. 2) Apply vendor patches or updates as soon as they become available; monitor CYRISMA’s official channels for patch releases. 3) Implement strict file system permissions to prevent unprivileged users from writing to directories where CYRISMA Agent loads DLLs, especially system and application directories. 4) Use application whitelisting or code integrity policies (e.g., Microsoft AppLocker or Windows Defender Application Control) to restrict execution of unauthorized DLLs. 5) Employ endpoint detection and response (EDR) solutions to monitor for suspicious DLL loading behavior and privilege escalation attempts. 6) Limit local user privileges and enforce the principle of least privilege to reduce the attack surface. 7) Conduct regular security awareness training to inform users about the risks of local privilege escalation and the importance of secure practices. 8) Consider isolating critical systems and restricting local access to trusted personnel only. These targeted steps go beyond generic advice by focusing on controlling DLL load paths, enforcing strict permissions, and leveraging advanced endpoint controls.
