CVE-2025-14491 is a local privilege escalation vulnerability identified in RealDefense SUPERAntiSpyware version 10.0.1276 Free Edition. The flaw is due to 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 vulnerability, the attacker can escalate their privileges to SYSTEM level, enabling arbitrary code execution with the highest system privileges. The vulnerability is classified under CWE-749, which refers to exposed dangerous methods or functions that can be misused. The CVSS v3.0 base score is 7.8, indicating high severity, with attack vector local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). This means that while the attacker must have some initial access to execute code locally, once achieved, the vulnerability allows full system compromise. No public exploits or patches are currently available, but the vulnerability has been published and assigned by ZDI (ZDI-CAN-27660). The lack of patches means organizations must rely on compensating controls until updates are released. The vulnerability primarily affects the Free Edition 10.0.1276 of SUPERAntiSpyware, a product used for malware detection and removal on Windows platforms.

For European organizations, this vulnerability poses a significant risk as it allows attackers who have already gained limited 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 persistent malware or ransomware. Organizations in sectors such as finance, healthcare, government, and critical infrastructure, where endpoint security products like SUPERAntiSpyware are deployed, could face severe operational and reputational damage. The high impact on confidentiality, integrity, and availability means that exploitation could lead to data breaches, system downtime, and loss of trust. Since the vulnerability requires local code execution, initial compromise vectors such as phishing, malicious insiders, or exploitation of other vulnerabilities could be leveraged to chain attacks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as threat actors often develop exploits rapidly after disclosure. European organizations must be vigilant, especially those with widespread use of this product or similar endpoint security solutions.

1. Restrict local code execution privileges by enforcing strict application whitelisting and least privilege principles to reduce the risk of initial low-privileged code execution. 2. Monitor and audit the SAS Core Service process for unusual behavior or privilege escalation attempts using endpoint detection and response (EDR) tools. 3. Implement strong user account controls and limit administrative privileges to reduce the attack surface. 4. Apply network segmentation to isolate critical systems and limit lateral movement opportunities. 5. Regularly update and patch all software components; although no patch is currently available, monitor vendor advisories closely and apply updates immediately upon release. 6. Educate users on phishing and social engineering risks to prevent initial compromise. 7. Consider deploying additional endpoint protection layers that can detect exploitation attempts targeting privilege escalation vulnerabilities. 8. Use system integrity monitoring to detect unauthorized changes to critical system files or services related to SUPERAntiSpyware.
