CVE-2026-11452 (GCVE-0-2026-11452)

Vulnerability from nvd – Published: 2026-06-07 03:15 – Updated: 2026-06-08 16:33

Title

GL.iNet GL-MT3000 SET_USER_PWD glc FUN_0042e200 command injection

Summary

A vulnerability has been found in GL.iNet GL-MT3000 up to 4.4.5. Affected is the function FUN_0042e200 of the file /cgi-bin/glc of the component SET_USER_PWD Handler. The manipulation of the argument Password leads to command injection. The attack can be initiated remotely. Upgrading to version 4.8.1 is able to address this issue. The affected component should be upgraded. The vendor explains: " The current code escapes single quotes in the password parameter and handles it inside a shell single‑quote context. The payloads in the report, which rely on $() or backticks to trigger command substitution, are not executed under the current code path. We tested on a GL‑MT3000 device running firmware 4.8.1 using similar payloads, and no command‑execution marker file was created."

CVE-2026-11451 (GCVE-0-2026-11451)

Vulnerability from nvd – Published: 2026-06-07 03:00 – Updated: 2026-06-08 16:32

Title

GL.iNet GL-MT3000 FTP Protocol glc snprintf command injection

Summary

A flaw has been found in GL.iNet GL-MT3000 4.4.5. This impacts the function snprintf of the file /cgi-bin/glc of the component FTP Protocol Handler. Executing a manipulation of the argument media_dir can lead to command injection. It is possible to launch the attack remotely. Upgrading to version 4.8.1 will fix this issue. You should upgrade the affected component. The vendor explains: "In version 4.8.1, before writing media_dir to the FTP configuration command, the code escapes single quotes using escape_single_quote(). The payloads in the report—which rely on closing a single quote, appending commands with a semicolon, and commenting out the tail with #—cannot escape execution under the current code path. We also verified this on a GL‑MT3000 device running firmware version 4.8.1 using similar payloads calling the /NAS_API_SET_PROTO_CONFIG interface. Although the interface returned success, the marker file intended to prove command execution was not created; the payload was written into /etc/vsftpd.conf only as ordinary configuration content and did not trigger any shell command execution. Therefore, with the current firmware version and default runtime environment, we could not reproduce the claimed “unauthorized command injection in set_proto_config”."

CVE-2026-11450 (GCVE-0-2026-11450)

Vulnerability from nvd – Published: 2026-06-07 02:30 – Updated: 2026-06-08 15:30

Title

GL.iNet GL-MT3000 Path Normalization dlopen command injection

Summary

A vulnerability was detected in GL.iNet GL-MT3000 4.4.5. This affects the function dlopen in the library /usr/lib/oui-httpd/rpc/ of the component Path Normalization Handler. Performing a manipulation of the argument dev_name results in command injection. It is possible to initiate the attack remotely. Upgrading to version 4.7 mitigates this issue. It is advisable to upgrade the affected component. The vendor confirms: " From version 4.7 onward, we have enabled method‑level validation at the HTTP /rpc layer. nas‑web.eject_disk is no longer in the whitelist of allowed methods. Consequently, directly calling eject_disk through the default /rpc endpoint returns Invalid params, preventing entry into subsequent dangerous functions and blocking the remote exploit chain described in the report."

The vendor confirms: \" From version 4.7 onward, we have enabled method\u2011level validation at the HTTP /rpc layer. nas\u2011web.eject_disk is no longer in the whitelist of allowed methods. Consequently, directly calling eject_disk through the default /rpc endpoint returns Invalid params, preventing entry into subsequent dangerous functions and blocking the remote exploit chain described in the report.\""

Title

GL.iNet GL-MT3000 LuCI JSON-RPC rpc rpc_sys command injection

Summary

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.

It is recommended to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

CVE-2026-11452 (GCVE-0-2026-11452)

Vulnerability from cvelistv5 – Published: 2026-06-07 03:15 – Updated: 2026-06-08 16:33

Title

GL.iNet GL-MT3000 SET_USER_PWD glc FUN_0042e200 command injection

Summary

A vulnerability has been found in GL.iNet GL-MT3000 up to 4.4.5. Affected is the function FUN_0042e200 of the file /cgi-bin/glc of the component SET_USER_PWD Handler. The manipulation of the argument Password leads to command injection. The attack can be initiated remotely. Upgrading to version 4.8.1 is able to address this issue. The affected component should be upgraded. The vendor explains: " The current code escapes single quotes in the password parameter and handles it inside a shell single‑quote context. The payloads in the report, which rely on $() or backticks to trigger command substitution, are not executed under the current code path. We tested on a GL‑MT3000 device running firmware 4.8.1 using similar payloads, and no command‑execution marker file was created."

The payloads in the report, which rely on $() or backticks to trigger command substitution, are not executed under the current code path. We tested on a GL\u2011MT3000 device running firmware 4.8.1 using similar payloads, and no command\u2011execution marker file was created.\""

CVE-2026-11451 (GCVE-0-2026-11451)

Vulnerability from cvelistv5 – Published: 2026-06-07 03:00 – Updated: 2026-06-08 16:32

Title

GL.iNet GL-MT3000 FTP Protocol glc snprintf command injection

Summary

A flaw has been found in GL.iNet GL-MT3000 4.4.5. This impacts the function snprintf of the file /cgi-bin/glc of the component FTP Protocol Handler. Executing a manipulation of the argument media_dir can lead to command injection. It is possible to launch the attack remotely. Upgrading to version 4.8.1 will fix this issue. You should upgrade the affected component. The vendor explains: "In version 4.8.1, before writing media_dir to the FTP configuration command, the code escapes single quotes using escape_single_quote(). The payloads in the report—which rely on closing a single quote, appending commands with a semicolon, and commenting out the tail with #—cannot escape execution under the current code path. We also verified this on a GL‑MT3000 device running firmware version 4.8.1 using similar payloads calling the /NAS_API_SET_PROTO_CONFIG interface. Although the interface returned success, the marker file intended to prove command execution was not created; the payload was written into /etc/vsftpd.conf only as ordinary configuration content and did not trigger any shell command execution. Therefore, with the current firmware version and default runtime environment, we could not reproduce the claimed “unauthorized command injection in set_proto_config”."

Vulnerability from cvelistv5 – Published: 2026-06-07 02:30 – Updated: 2026-06-08 15:30

Title

GL.iNet GL-MT3000 Path Normalization dlopen command injection

Summary

A vulnerability was detected in GL.iNet GL-MT3000 4.4.5. This affects the function dlopen in the library /usr/lib/oui-httpd/rpc/ of the component Path Normalization Handler. Performing a manipulation of the argument dev_name results in command injection. It is possible to initiate the attack remotely. Upgrading to version 4.7 mitigates this issue. It is advisable to upgrade the affected component. The vendor confirms: " From version 4.7 onward, we have enabled method‑level validation at the HTTP /rpc layer. nas‑web.eject_disk is no longer in the whitelist of allowed methods. Consequently, directly calling eject_disk through the default /rpc endpoint returns Invalid params, preventing entry into subsequent dangerous functions and blocking the remote exploit chain described in the report."

CVE-2026-11449 (GCVE-0-2026-11449)

Vulnerability from cvelistv5 – Published: 2026-06-07 02:15 – Updated: 2026-06-09 14:57

Title

GL.iNet GL-MT3000 LuCI JSON-RPC rpc rpc_sys command injection

Summary

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."
