CVE-2025-49083 is a deserialization vulnerability identified in the management console of Absolute Security's Secure Access product, specifically affecting versions after 12.00 and prior to 13.56. The vulnerability arises from unsafe deserialization of content within the console, which can be exploited by an attacker who already has administrative privileges on the console. This unsafe deserialization allows execution of arbitrary code within the security context of the management console. The attack complexity is low, meaning it does not require sophisticated techniques, and no user interaction is necessary. However, the attacker must have high-level privileges (administrative access) to the console to exploit this vulnerability. The vulnerability primarily impacts the integrity of the system, allowing an attacker to potentially alter or manipulate data or configurations within the console. Confidentiality impact is low, indicating limited exposure of sensitive data, and availability is not affected. Additionally, the vulnerability has limited impact on subsequent systems connected or managed by the console, with low confidentiality and integrity impact and no availability impact. The vulnerability is classified under CWE-502 (Deserialization of Untrusted Data), a common weakness that can lead to remote code execution or privilege escalation if exploited. The CVSS 4.0 base score is 7.0 (high severity), reflecting the significant risk posed by this vulnerability given the ease of exploitation and the high privileges required. No known exploits are currently reported in the wild, and no official patches have been linked yet. Organizations using Absolute Secure Access versions between 12.00 and 13.56 should prioritize upgrading or applying mitigations once available to prevent potential exploitation.

For European organizations, the impact of CVE-2025-49083 is significant primarily in environments where Absolute Secure Access is deployed for managing secure access and network security. Since the vulnerability requires administrative access to the management console, the threat is most relevant in scenarios where internal threat actors or compromised administrator accounts exist. Exploitation could lead to unauthorized modification of security policies, configurations, or access controls, undermining the integrity of the security infrastructure. This could facilitate further attacks, lateral movement, or data manipulation within the organization. Although confidentiality and availability impacts are low or none, the integrity compromise can disrupt trust in security controls and potentially expose organizations to compliance risks, especially under stringent European data protection regulations such as GDPR. The lack of required user interaction and low attack complexity increases the risk if administrative credentials are compromised. Given the critical role of Secure Access in controlling network entry points, any compromise could have cascading effects on organizational security posture. Therefore, European enterprises relying on this product should consider this vulnerability a high priority for remediation to maintain operational security and regulatory compliance.

1. Immediate mitigation should focus on restricting and monitoring administrative access to the Absolute Secure Access management console. Implement strict access controls, multi-factor authentication (MFA), and regular auditing of admin accounts and activities. 2. Network segmentation should be enforced to limit access to the management console only to trusted administrative networks and personnel. 3. Employ application-layer protections such as Web Application Firewalls (WAFs) to detect and block suspicious deserialization payloads or anomalous requests targeting the console. 4. Monitor logs and alerts for unusual behavior indicative of exploitation attempts, including unexpected configuration changes or code execution traces. 5. Engage with Absolute Security for official patches or updates addressing this vulnerability and plan for prompt deployment once available. 6. Conduct internal security awareness and training focused on safeguarding administrative credentials and recognizing potential insider threats. 7. As a longer-term measure, evaluate the security posture of the Secure Access deployment and consider alternative solutions or additional compensating controls if patching is delayed. 8. Implement runtime application self-protection (RASP) or endpoint detection and response (EDR) tools to detect and prevent exploitation attempts in real-time.
