NVD-CWE-noinfoPublished: May 10, 2023· Updated: Jun 17, 2026
Official Description
An issue was discovered on GL.iNet devices before 3.216. Through the software installation feature, it is possible to install arbitrary software, such as a reverse shell, because the restrictions on the available package list are limited to client-side verification. It is possible to install software from the filesystem, the package list, or a URL.
Risk Analysis
GL.iNet devices are vulnerable to arbitrary software installation due to insufficient client-side verification of the package list. This critical flaw allows an attacker to install malicious software, such as a reverse shell, and is remotely exploitable with low complexity.
There is no known public exploit for this vulnerability, and it is not listed in CISA's KEV catalog.
Users should update their device firmware to version 3.216 or later to address the package installation restrictions.
Technical Analysis
CVE-2023-31471 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.
