CVE-2025-49083
Published: 31 July 2025
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, ranked in the top 19.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
