Summary

CVE-2025-49083 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Absolute Secure Access. Its CVSS base score is 7.0 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 30th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-49083 is a deserialization vulnerability, tracked as CWE-502, that affects the management console of Absolute Secure Access in versions after 12.00 and prior to 13.56. The flaw allows unsafe content to be deserialized and executed within the console process, producing a CVSS 4.0 score of 7.0 driven by low attack complexity, high privileges required, and a high integrity impact with only low confidentiality impact and no availability impact.

An attacker who already possesses administrative access to the console can supply malicious serialized data that executes in the console's security context. No user interaction or additional attack prerequisites are needed, enabling the adversary to achieve code execution that affects the integrity of the console and, to a lesser extent, subsequent systems.

The vendor advisory published at https://www.absolute.com/platform/security-information/vulnerability-archive/cve-2025-49083 documents the affected range and indicates that the issue is resolved in version 13.56. The associated EPSS score remains flat at 0.0132 with no material increase since disclosure.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can uncover deserialization flaws before deployment.

Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.

Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.

Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 none match
prevents

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

finds

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.

prevents

Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.

finds

Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
