AI Analysis
Technical Summary
This vulnerability affects GL.iNet BE9300 and MT6000 devices with firmware versions 4.8.0 up to but not including 4.9.0. The flaw exists in the Firewall-management RPC component where manipulation of the dest_port or dest_ip arguments leads to OS command injection. The vendor has confirmed the existence of this vulnerability and recommends upgrading to version 4.9.0 to remediate the issue. The CVSS 4.0 base score is 5.3 (medium), reflecting network attack vector, low complexity, no user interaction, and limited privileges required.
Potential Impact
Successful exploitation allows a remote attacker with low privileges to execute arbitrary OS commands on affected devices, potentially compromising device integrity and confidentiality. The impact is limited by the requirement of low privileges and the low scope and impact metrics in the CVSS vector.
Mitigation Recommendations
Upgrade affected GL.iNet BE9300 and MT6000 devices from versions >=4.8.0 and <4.9.0 to version 4.9.0 or later. This upgrade addresses the OS command injection vulnerability in the Firewall-management RPC component. No other mitigation steps are indicated by the vendor.
