This vulnerability exists in GL.iNet routers including models A1300, AX1800, AXT1800, BE1400, BE3600, BE6500, BE9300, BE10000, E5800, MT2500, MT3000, MT3600BE, MT5000, MT6000, X2000, X3000, and XE3000 running firmware versions 4.0 through 4.8. It is located in the Wi-Fi Timer Power-Schedule feature where improper handling of the switch_power/restore_power argument allows remote attackers to perform OS command injection. The vendor has confirmed the vulnerability but has not yet released a patch or official remediation. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and low to limited impacts on confidentiality, integrity, availability, scope, and security requirements.

Successful exploitation allows remote attackers to execute arbitrary OS commands on affected GL.iNet devices. This could lead to unauthorized control or disruption of the device. The impact is rated medium severity with a CVSS 4.0 score of 5.3. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, users should consider disabling the Wi-Fi Timer Power-Schedule feature if possible or restrict network access to the device to trusted sources to reduce exposure.
