CVE-2026-44089 (GCVE-0-2026-44089)

Vulnerability from nvd – Published: 2026-06-23 12:08 – Updated: 2026-06-23 13:32

Title

Buffer Overflow in Totolink EX1200L router

Summary

Totolink EX1200L router is vulnerable to Buffer Overflow in the login functionality in cgi-bin/cstecgi.cgi endpoint. This vulnerability could be exploited to cause the program to crash and to execute code remotely. This allows the attacker to perform actions as root including reading and editing data, as well as bricking the router. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 9.3.5u.6146_B20201023 but may also affect other versions.

Severity

9.4 (Critical)

CVE-2026-44089 (GCVE-0-2026-44089)

Vulnerability from cvelistv5 – Published: 2026-06-23 12:08 – Updated: 2026-06-23 13:32

Title

Buffer Overflow in Totolink EX1200L router

Summary

Totolink EX1200L router is vulnerable to Buffer Overflow in the login functionality in cgi-bin/cstecgi.cgi endpoint. This vulnerability could be exploited to cause the program to crash and to execute code remotely. This allows the attacker to perform actions as root including reading and editing data, as well as bricking the router. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 9.3.5u.6146_B20201023 but may also affect other versions.

Severity

9.4 (Critical)

VAR-202312-0940

Vulnerability from variot - Updated: 2025-07-10 23:01

TOTOlink EX1200L V9.3.5u.6146_B20201023 is vulnerable to arbitrary command execution via the cstecgi.cgi UploadFirmwareFile interface. TOTOLINK of ex1200l Firmware has an unrestricted upload of dangerous file types vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK EX1200L is a dual-band wireless signal amplifier, mainly used to expand the Wi-Fi coverage of home or office environments, and solve the problem of weak signals or dead spots.

TOTOLINK EX1200L has a command execution vulnerability, which is caused by the UploadFirmwareFil function interface of cstecgi.cgi failing to properly filter special characters and commands in constructed commands

VAR-202408-0215

Vulnerability from variot - Updated: 2025-07-09 23:07

A vulnerability, which was classified as critical, was found in TOTOLINK EX1200L 9.3.5u.6146_B20201023. This affects the function setParentalRules of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument week/sTime/eTime leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-273261 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of ex1200l Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK EX1200L is a dual-band wireless signal amplifier launched by China Jiong Electronics, mainly used to expand Wi-Fi coverage. No detailed vulnerability details are currently provided
