CVE-2024-39227

CVSS 9.8v3.1pub. 2024-08-06upd. 2024-08-15

GL-iNet products AR750/AR750S/AR300M/AR300M16/MT300N-V2/B1300/MT1300/SFT1200/X750 v4.3.11, MT3000/MT2500/AXT1800/AX1800/A1300/X300B v4.5.16, XE300 v4.3.16, E750 v4.3.12, AP1300/S1300 v4.3.13, and XE3000/X3000 v4.4 were discovered to contain insecure permissions in the endpoint /cgi-bin/glc. This vulnerability allows unauthenticated attackers to execute arbitrary code or possibly a directory traversal via crafted JSON data.

🤖 AI Analysis
How it works

The /cgi-bin/glc endpoint has improperly configured permissions that do not require authentication before processing requests. An attacker can send crafted JSON data to this endpoint, which leads to arbitrary code execution or enables path traversal on the device's file system. The vulnerability is classified as CWE-74 (injection) and CWE-75 (failure to sanitize special elements), indicating a lack of proper input validation and sanitization.

Impact

An attacker can remotely execute arbitrary code on the device (RCE) without needing any credentials, and also gain unauthorized access to any files on the system through path traversal, which may lead to full compromise of the router.

Mitigation & patch

Apply patches available from the manufacturer according to references. It is recommended to monitor the manufacturer's repository at https://github.com/gl-inet/CVE-issues and update the firmware to patched versions as soon as possible. Until the update is applied, access to the device's administrative panel should be restricted to trusted networks only or remote access to the management interface should be disabled.
