CVE-2026-11449: Command Injection in GL.iNet GL-MT3000
A security vulnerability has been detected in GL.iNet GL-MT3000 4.4.5. The impacted element is the function rpc_sys of the file /cgi-bin/luci/rpc of the component LuCI JSON-RPC Interface. Such manipulation leads to command injection. The attack may be performed from remote. Upgrading to version 4.8.1 is sufficient to resolve this issue. Upgrading the affected component is advised. The vendor confirms: "The issue discovered by the vulnerability researcher on older firmware versions(4.4.5) has actually been fixed and mitigated in the new version. According to the latest firmware fixes, by default, firmware versions after 4.7.13 do not install LuCI, so this vulnerability cannot be exploited."
AI Analysis
Technical Summary
CVE-2026-11449 is a command injection vulnerability in the GL.iNet GL-MT3000 device, specifically in the rpc_sys function of the /cgi-bin/luci/rpc LuCI JSON-RPC Interface component. The vulnerability affects firmware version 4.4.5 and allows remote attackers to execute arbitrary commands via crafted input. The vendor confirms that the vulnerability is fixed in version 4.8.1 and that firmware versions after 4.7.13 do not include the vulnerable LuCI component by default, preventing exploitation in those versions.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to execute arbitrary commands on affected devices running firmware 4.4.5, potentially leading to unauthorized control or disruption of the device. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low complexity, no user interaction, and limited confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Upgrade affected devices from firmware version 4.4.5 to version 4.8.1 or later. Devices running firmware versions after 4.7.13 are not vulnerable by default because the LuCI interface is not installed. No additional mitigations are indicated by the vendor.
