Descriptions

N6854A Geolocation Server versions 2.4.2 are vulnerable to untrusted data deserialization, which may allow a malicious actor to escalate privileges in the affected device’s default configuration and achieve remote code execution.

This vulnerability allows local attackers to escalate privileges on affected installations of KeySight N6841A RF Sensor. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the LAHttpInvokerServiceExporter class. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.

*Credits: An anonymous individual working with Trend Micro’s Zero Day Initiative reported this vulnerability to CISA.
