CWE-502Published: March 27, 2023· Updated: Jun 17, 2026
Official Description
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.
Risk Analysis
The N6854A Geolocation Server is vulnerable to untrusted data deserialization, which can lead to privilege escalation and remote code execution. With a CVSS score of 9.8, this is a critical flaw that allows full system compromise without authentication.
There is no known public exploit for this vulnerability, and it is not currently listed in the CISA KEV catalog. The vulnerability is remotely exploitable with low attack complexity.
Users should update to the latest firmware version provided by Keysight to address the deserialization flaw.
Technical Analysis
CVE-2023-1399 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
