CVE-2025-57624 is a DLL hijacking vulnerability identified in CYRISMA Agent versions prior to 444. DLL hijacking occurs when an application loads a malicious Dynamic Link Library (DLL) instead of the legitimate one, allowing an attacker to execute arbitrary code within the context of the vulnerable application. In this case, the vulnerability enables local users to escalate privileges by exploiting multiple DLLs loaded by the CYRISMA Agent. This means that an attacker with local access to the affected system can replace or insert malicious DLL files that the CYRISMA Agent loads, thereby gaining higher privileges than originally granted. The vulnerability does not require remote exploitation or user interaction beyond local access, but it leverages the trust and execution context of the CYRISMA Agent, which likely runs with elevated privileges or system-level access. Although no specific affected versions are listed beyond 'before 444', it is clear that the issue affects all versions prior to this update. No CVSS score has been assigned yet, and there are no known exploits in the wild at the time of publication. The lack of patch links suggests that a fix may not have been publicly released or documented at the time of this report. DLL hijacking vulnerabilities are particularly dangerous because they can be exploited silently and can lead to full system compromise if the targeted application runs with high privileges. CYRISMA Agent is presumably a security or monitoring agent, which often runs with elevated permissions, increasing the potential impact of this vulnerability.

For European organizations, the impact of this vulnerability can be significant, especially if CYRISMA Agent is deployed widely within their IT environments. Since the vulnerability allows local privilege escalation, an attacker who gains any form of local access—such as through phishing, physical access, or other initial footholds—could leverage this flaw to gain administrative or system-level control. This could lead to unauthorized access to sensitive data, disruption of security monitoring capabilities, and potential lateral movement within the network. The integrity and availability of systems could be compromised if attackers execute arbitrary code to disable security controls or deploy ransomware. Confidentiality is also at risk if attackers use elevated privileges to exfiltrate data. The absence of known exploits in the wild currently reduces immediate risk, but the vulnerability's nature and the elevated privileges of the CYRISMA Agent make it a high-value target for attackers once exploit code becomes available. European organizations in sectors with high security requirements, such as finance, healthcare, government, and critical infrastructure, could face severe consequences if this vulnerability is exploited.

Organizations should prioritize identifying all instances of CYRISMA Agent deployed within their environments and verify the version in use. Immediate mitigation steps include: 1) Applying any available patches or updates from the vendor that address this vulnerability, especially upgrading to version 444 or later. 2) If patches are not yet available, implement strict file system permissions to prevent unauthorized users from writing or replacing DLL files in directories used by CYRISMA Agent. 3) Employ application whitelisting and integrity monitoring to detect unauthorized changes to DLL files. 4) Restrict local user privileges to the minimum necessary to reduce the risk of privilege escalation. 5) Monitor logs and system behavior for signs of DLL hijacking attempts or unusual privilege escalations. 6) Educate users about the risks of local access compromise and enforce strong physical and network access controls. 7) Consider isolating systems running CYRISMA Agent to limit exposure. These measures go beyond generic advice by focusing on controlling DLL file integrity and minimizing local user privileges, which are critical to mitigating DLL hijacking risks.
