CVE-2025-14495 is a local privilege escalation vulnerability affecting RealDefense SUPERAntiSpyware version 10.0.1276 Free Edition. The vulnerability arises from an exposed dangerous function within the SAS Core Service component, which improperly exposes functionality that can be leveraged by an attacker. To exploit this flaw, an attacker must first gain the ability to execute code with low privileges on the target system, such as through a separate vulnerability or local access. Once this foothold is established, the attacker can invoke the exposed function to escalate privileges to SYSTEM level, the highest privilege on Windows systems. This escalation allows execution of arbitrary code with full system rights, potentially leading to complete system compromise. The vulnerability is identified as CWE-749, indicating exposure of dangerous methods or functions that should not be accessible. The CVSS v3.0 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no user interaction required. No public exploits or patches are currently available, but the vulnerability was published on December 23, 2025, and tracked under ZDI-CAN-27677. The affected product is primarily used on Windows endpoints, and the Free Edition 10.0.1276 is specifically vulnerable. This vulnerability poses a significant risk in environments where attackers can gain initial low-level access, enabling them to fully compromise affected systems.

For European organizations, this vulnerability presents a serious risk as it enables attackers who have limited local access to escalate privileges to SYSTEM level, potentially leading to full system compromise. This can result in unauthorized access to sensitive data, disruption of critical services, and the ability to deploy further malware or ransomware. Organizations relying on RealDefense SUPERAntiSpyware for endpoint protection may face reduced security posture if this vulnerability is exploited. The impact is particularly critical in sectors with sensitive data such as finance, healthcare, and government, where confidentiality and integrity are paramount. Additionally, availability can be affected if attackers disable security controls or disrupt system operations. The lack of a patch increases the window of exposure, making proactive mitigation essential. Since exploitation requires prior local code execution, the overall risk is mitigated if organizations have strong perimeter defenses and endpoint controls, but insider threats or chained attacks remain a concern.

1. Immediately audit and restrict local user permissions to minimize the risk of low-privileged code execution. 2. Implement strict application whitelisting and endpoint detection and response (EDR) solutions to detect and block suspicious local activities. 3. Monitor logs for unusual invocations of the SAS Core Service or unexpected privilege escalations. 4. Isolate systems running the vulnerable version of SUPERAntiSpyware to limit exposure. 5. Educate users and administrators about the risk of executing untrusted code locally. 6. Coordinate with RealDefense for timely updates and apply patches as soon as they are released. 7. Consider temporary removal or replacement of the affected SUPERAntiSpyware version in critical environments until a fix is available. 8. Employ network segmentation to limit lateral movement if a system is compromised. 9. Regularly review and update endpoint security policies to reduce attack surface. 10. Use multi-factor authentication and strong access controls to prevent unauthorized local access.
