CVE-2025-49083 is a vulnerability in the management console of Absolute Secure Access after version 12.00 and prior to version 13.56. Attackers with administrative access to the console can cause unsafe content to be deserialized and executed in the security context of the console. The attack complexity is low and there are no attack requirements. Privileges required are high and there is no user interaction required. The impact to confidentiality is low, impact to integrity is high and there is no impact to availability. The impact to the confidentiality and integrity of subsequent systems is low and there is no subsequent system impact to availability.
The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid.

It is often convenient to serialize objects for communication or to save them for later use. However, deserialized data or code can often be modified without using the provided accessor functions if it does not use cryptography to protect itself. Furthermore, any cryptography would still be client-side security – which is a dangerous security assumption. Data that is untrusted can not be trusted to be well-formed. When developers place no restrictions on “gadget chains,” or series of instances and method invocations that can self-execute during the deserialization process (i.e., before the object is returned to the caller), it is sometimes possible for attackers to leverage them to perform unauthorized actions, like generating a shell.
