CVE-2023-4667
CWE-79Published: November 28, 2023· Updated: Jun 17, 2026
Official Description
The web interface of the PAC Device allows the device administrator user profile to store malicious scripts in some fields. The stored malicious script is then executed when the GUI is opened by any users of the webserver administration interface.
The root cause of the vulnerability is inadequate input validation and output encoding in the web administration interface component of the firmware.
This could lead to unauthorized access and data leakage
Technical Analysis
CVE-2023-4667 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
