OS command injection in GL.iNet routers running firmware up to 4.8.x allows an authenticated remote attacker to execute arbitrary shell commands via the Wi-Fi Timer Power-Schedule feature by manipulating the switch_power or restore_power arguments. The vendor has independently confirmed the vulnerability exists. A public write-up exists in the vendor's own CVE issues repository describing the attack as a cron-based RCE path, and no public exploit with KEV listing has been identified at time of analysis. The CVSS 4.0 score of 5.3 (with PR:L) reflects that low-privilege authentication is required, but the real-world impact of arbitrary command execution on a network router warrants elevated attention beyond what the score conveys.
Code injection in GL.iNet router firmware's Language Auto-Update component allows low-privileged authenticated remote attackers to execute arbitrary OS-level commands by manipulating cron scheduling parameters in the ui.update_langs function. Seventeen router models running firmware up to version 4.8.x are affected, spanning GL.iNet's entire current lineup from travel routers (MT3000, AXT1800) to high-end mesh units (BE10000, BE9300). The vendor has confirmed the vulnerability exists and a patch is available via the GL.iNet CVE issues repository; no public exploit code or CISA KEV listing has been identified at time of analysis.
Authorization bypass in the WebDAV Service COPY/MOVE operations on seventeen GL.iNet router models running firmware up to 4.8.x allows remote unauthenticated attackers to read and write files outside their authorized share boundaries. The root cause, per the GitHub reference title 'WebDAV Public-Share Destination Authorization Bypass', is that the destination path supplied in COPY/MOVE requests is not properly authorization-checked against the caller's access scope - a classic CWE-639 user-controlled key bypass. The vendor has independently confirmed the vulnerability exists. No public exploit code or CISA KEV listing is identified at time of analysis.
Heap-based buffer overflow in the GL.iNet APPS-NAS module's nas-web.get_file_list function allows authenticated remote attackers to crash the NAS service on eleven router models running firmware up to 20260707, resulting in a denial of service. The vendor confirmed the vulnerability following responsible disclosure, and the GitHub advisory explicitly identifies the impact as authenticated denial of service with no confidentiality or integrity compromise. No public exploit code has been identified and the vulnerability is not listed in CISA KEV at time of analysis.
Improper authorization in GL.iNet's eSIM LPA API allows adjacent-network unauthenticated attackers to bypass nginx proxy controls on six cellular router models, gaining unauthorized access to eSIM management functions. Affected devices include the E5800, E750, X2000, X3000, XE3000, and XE300 running firmware up to 20260707. The GitHub advisory title explicitly frames this as 'Unauthenticated access to eSIM LPA API via nginx proxy bypass,' indicating the authorization enforcement failure lies in how nginx proxies requests to the /sdk/v1 endpoint. No public exploit code or CISA KEV listing has been identified at time of analysis.
