CWE-502Published: July 22, 2020· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of NEC ESMPRO Manager 6.42. Authentication is not required to exploit this vulnerability. The specific flaw exists within the RMI service. 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 execute code in the context of SYSTEM. Was ZDI-CAN-10007.

Technical Analysis

CVE-2020-10917 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.
