CWE-284Published: October 29, 2018· Updated: Jun 17, 2026
7.8
CVSS v3.1
Official Description
WebAccess Versions 8.3.2 and prior. During installation, the application installer disables user access control and does not re-enable it after the installation is complete. This could allow an attacker to run elevated arbitrary code.
Technical Analysis
CVE-2018-17908 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low 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 7.8.
