CVE-2026-11449: Command Injection in GL.iNet GL-MT3000
CVE-2026-11449 is a command injection vulnerability in the GL. iNet GL-MT3000 router firmware version 4. 4. 5. The flaw exists in the rpc_sys function of the /cgi-bin/luci/rpc component within the LuCI JSON-RPC interface, allowing remote attackers to execute arbitrary commands. This vulnerability is resolved by upgrading to firmware version 4. 8. 1 or later. Additionally, firmware versions after 4. 7.
AI Analysis
Technical Summary
The GL.iNet GL-MT3000 router firmware version 4.4.5 contains a command injection vulnerability in the rpc_sys function of the /cgi-bin/luci/rpc endpoint, part of the LuCI JSON-RPC interface. This vulnerability allows remote attackers to execute arbitrary commands on the device. The vendor has fixed this issue in firmware version 4.8.1 and later. Furthermore, starting with firmware version 4.7.13, the LuCI interface is not installed by default, preventing exploitation of this vulnerability in those versions.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary commands on the affected device, potentially leading to unauthorized control or disruption of the router. The CVSS 4.0 base score is 5.3, indicating a medium severity level. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade the GL.iNet GL-MT3000 firmware to version 4.8.1 or later, where the vulnerability is fixed. Alternatively, using firmware versions after 4.7.13 is effective since these versions do not install the vulnerable LuCI interface by default, mitigating the risk. No additional mitigation actions are required beyond upgrading.
