CVE-2025-14493 is a high-severity local privilege escalation vulnerability identified in RealDefense SUPERAntiSpyware Free Edition version 10.0.1276. The root cause is an exposed dangerous method within the SAS Core Service component, which improperly exposes functionality that 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, effectively gaining full control over the system. This allows arbitrary code execution with the highest privileges, potentially leading to complete system compromise, data theft, or disruption of security services. The vulnerability is classified under CWE-749, indicating exposure of dangerous methods or functions that should be protected. The CVSS v3.0 score of 7.8 reflects the vulnerability’s high impact on confidentiality, integrity, and availability, with low attack complexity but requiring local privileges and no user interaction. Although no public exploits are known at this time, the vulnerability poses a significant risk to environments where attackers can gain initial low-level access, such as through phishing, malware, or insider threats. No patches have been released yet, so mitigation currently relies on limiting local access and monitoring.

For European organizations, this vulnerability presents a significant risk especially in environments where RealDefense SUPERAntiSpyware is deployed on endpoints. Successful exploitation can lead to full system compromise, allowing attackers to bypass security controls, access sensitive data, and disrupt operations. Critical sectors such as finance, healthcare, and government agencies could face severe consequences including data breaches, loss of system integrity, and operational downtime. The requirement for local code execution means that initial compromise vectors like phishing or malware delivery could be leveraged to escalate privileges, increasing the overall attack surface. Additionally, the lack of a patch means organizations must rely on compensating controls, increasing operational complexity. The impact on confidentiality, integrity, and availability is high, making this a priority vulnerability to address in European IT environments.

1. Restrict local user permissions rigorously to prevent unauthorized code execution on endpoints running SUPERAntiSpyware. 2. Implement application whitelisting and endpoint detection and response (EDR) solutions to monitor and block suspicious activities related to the SAS Core Service. 3. Enforce strict network segmentation and least privilege principles to limit lateral movement if initial access is gained. 4. Monitor system logs and security events for unusual privilege escalation attempts or SAS Core Service anomalies. 5. Educate users on phishing and malware risks to reduce the likelihood of initial low-privilege code execution. 6. Engage with RealDefense support channels to obtain patches or updates as soon as they become available and prioritize timely deployment. 7. Consider temporary removal or replacement of the affected SUPERAntiSpyware version in high-risk environments until a patch is released.
