CVE-2021-43176

CWE-23Published: December 7, 2021· Updated: Jun 17, 2026

8.8

CVSS v3.1

Official Description

The GOautodial API prior to commit 3c3a979 made on October 13th, 2021 takes a user-supplied “action” parameter and appends a .php file extension to locate and load the correct PHP file to implement the API call. Vulnerable versions of GOautodial do not sanitize the user input that specifies the action. This permits an attacker to execute any PHP source file with a .php extension that is present on the disk and readable by the GOautodial web server process. Combined with CVE-2021-43175, it is possible for the attacker to do this without valid credentials. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C

Technical Analysis

CVE-2021-43176 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

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 8.8.
