CVE-2018-10239

CWE-264Published: June 17, 2019· Updated: Jun 17, 2026

6.7

CVSS v3.1

Official Description

A privilege escalation vulnerability in the "support access" feature on Infoblox NIOS 6.8 through 8.4.1 could allow a locally authenticated administrator to temporarily gain additional privileges on an affected device and perform actions within the super user scope. The vulnerability is due to a weakness in the "support access" password generation algorithm. A locally authenticated administrative user may be able to exploit this vulnerability if the "support access" feature is enabled, they know the support access code for the current session, and they know the algorithm to generate the support access password from the support access code. "Support access" is disabled by default. When enabled, the access will be automatically disabled (and support access code will expire) after the 24 hours.

Technical Analysis

CVE-2018-10239 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

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 6.7.
