CVE-2025-14493 is a local privilege escalation vulnerability identified in RealDefense SUPERAntiSpyware, specifically version 10.0.1276 Free Edition. The vulnerability arises from an exposed dangerous function within the SAS Core Service component, which can be leveraged by an attacker who already has the ability to execute code with low privileges on the affected system. By exploiting this flaw, the attacker can escalate their privileges to SYSTEM level, the highest privilege on Windows systems, enabling arbitrary code execution with full control over the system. The vulnerability is classified under CWE-749, indicating an exposed dangerous method or function that should not be accessible or callable by untrusted code. The CVSS v3.0 base score is 7.8, reflecting high severity due to the combination of local attack vector, low complexity, required privileges, and the impact on confidentiality, integrity, and availability. No user interaction is required for exploitation, but the attacker must have initial low-privileged code execution, which could be achieved through other means such as phishing, malware, or exploiting other vulnerabilities. Currently, there are no known public exploits or patches available, increasing the urgency for organizations to implement interim mitigations. The vulnerability was published on December 23, 2025, and was assigned by the Zero Day Initiative (ZDI) under identifier ZDI-CAN-27675. The absence of patches means that affected users must rely on limiting local access and monitoring for suspicious activity until a vendor fix is released.

For European organizations, this vulnerability poses a significant risk as it allows attackers who have already compromised a system with limited privileges to gain full SYSTEM-level control. This can lead to complete system compromise, data theft, disruption of services, and the potential for lateral movement within corporate networks. The impact on confidentiality is high because attackers can access sensitive data; integrity is compromised as attackers can modify or delete data and system configurations; availability is at risk due to potential system instability or denial-of-service conditions caused by malicious code running with SYSTEM privileges. Organizations relying on RealDefense SUPERAntiSpyware for endpoint protection may face a paradox where their security software becomes an attack vector. This is particularly concerning for sectors with strict data protection regulations such as finance, healthcare, and government agencies across Europe. The lack of a patch increases the window of exposure, and the requirement for local code execution means that insider threats or malware infections could exploit this vulnerability to escalate privileges.

Until an official patch is released by RealDefense, European organizations should implement specific mitigations: 1) Restrict local user permissions to prevent unauthorized code execution, including limiting software installation rights and use of removable media. 2) Employ application whitelisting to block unauthorized executables from running. 3) Monitor endpoints for unusual local process activity, especially those involving the SAS Core Service or related processes. 4) Use endpoint detection and response (EDR) tools to detect privilege escalation attempts. 5) Conduct regular audits of installed software versions and remove or upgrade vulnerable versions where possible. 6) Educate users about phishing and malware risks to reduce chances of initial low-privilege code execution. 7) Isolate critical systems and apply network segmentation to limit lateral movement if compromise occurs. 8) Prepare incident response plans specifically addressing local privilege escalation scenarios. 9) Engage with the vendor for timely updates and subscribe to vulnerability advisories. These targeted actions go beyond generic advice by focusing on controlling local execution and monitoring the specific vulnerable component.
