GL.iNet GL-MT3000 Command Injection Flaws

Command injection in GL.iNet GL-MT3000 router firmware 4.4.5 allows remote attackers to inject shell commands via the media_dir parameter handled by the snprintf call in /cgi-bin/glc's FTP protocol handler. The CVSS vector indicates network-reachable, unauthenticated exploitation with low complexity, and publicly available exploit code exists on GitHub (StrTzz123/iot_vul). The vendor has issued firmware 4.8.1 and disputes reproducibility on the patched build, stating that escape_single_quote() now sanitizes the input before it reaches the FTP configuration write path.

Command injection in GL.iNet GL-MT3000 router firmware 4.4.5 allows remote attackers to execute arbitrary OS commands by manipulating the dev_name argument passed to the dlopen function in the /usr/lib/oui-httpd/rpc/ Path Normalization Handler, reachable via the nas-web.eject_disk RPC method. Publicly available exploit code exists on GitHub demonstrating the chain. No CISA KEV listing and EPSS data was not provided, but the network-reachable, no-authentication CVSS vector combined with public PoC makes this a meaningful risk for exposed devices.

Command injection in GL.iNet GL-MT3000 routers running firmware up to 4.4.5 allows remote attackers to inject shell commands through the Password argument of the SET_USER_PWD handler in /cgi-bin/glc (function FUN_0042e200). The flaw is network-reachable with low complexity, but no public exploit is identified at time of analysis and the vendor disputes practical exploitability, stating that single-quote escaping in the shell context blocks the reported $() and backtick payloads.

Command injection in GL.iNet GL-MT3000 router firmware 4.4.5 allows a remote, low-privileged attacker to execute arbitrary OS commands via the `rpc_sys` function exposed through the LuCI JSON-RPC interface at `/cgi-bin/luci/rpc`. The vendor has confirmed the vulnerability and released a fix in firmware 4.8.1; critically, versions after 4.7.13 no longer install LuCI by default, eliminating the attack surface for most current deployments. Publicly available exploit code exists in a GitHub repository, though no active exploitation has been confirmed by CISA KEV.

Remote command injection in GL.iNet GL-MT3000 firmware versions up to 4.4.5 enables a network-reachable, high-privilege attacker to execute arbitrary OS commands through the Minidlna service's /rpc endpoint by manipulating the kube.set argument of the realpath function. The vendor has confirmed the vulnerability and released a fix in firmware version 4.7, citing SDK-level global sanitization as the remediation. Publicly available exploit code exists in a GitHub proof-of-concept repository (StrTzz123/iot_vul), though no active exploitation has been confirmed by CISA KEV at time of analysis.

Command injection in GL.iNet GL-MT3000 router firmware (versions up to 4.4.5) allows a low-privileged remote attacker to execute arbitrary OS commands by manipulating the 'device' argument passed to the iwinfo_backend function in iwinfo.so. A public proof-of-concept exploit is available on GitHub, raising the realistic likelihood of opportunistic abuse. The vendor has confirmed the issue and released firmware 4.7 with a global injection interception protection in the SDK.
