VAR-202511-0871
Vulnerability from variot - Updated: 2025-12-20 23:36A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (sub_42F32C function). The web interface reads the "lang" parameter and constructs Help URL strings using sprintf() into fixed-size stack buffers without proper length validation. Maliciously crafted input can overflow these buffers, potentially leading to arbitrary code execution or memory corruption, without requiring authentication

VAR-202511-1324
Vulnerability from variot - Updated: 2025-11-22 23:11A local stack-based buffer overflow vulnerability exists in the infostat.cgi and cstecgi.cgi binaries of ToToLink routers (A720R V4.1.5cu.614_B20230630, LR1200GB V9.1.0u.6619_B20230130, and NR1800X V9.1.0u.6681_B20230703). Both programs parse the contents of /proc/net/arp using sscanf() with "%s" format specifiers into fixed-size stack buffers without length validation. Specifically, one function writes user-controlled data into a single-byte buffer, and the other into adjacent small arrays without bounds checking. An attacker who controls the contents of /proc/net/arp can trigger memory corruption, leading to denial of service or potential arbitrary code execution

VAR-202511-1434
Vulnerability from variot - Updated: 2025-11-20 23:33A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (setDefResponse function). The binary reads the "IpAddress" parameter from a web request and copies it into a fixed-size stack buffer using strcpy() without any length validation. Maliciously crafted input can overflow the buffer, leading to potential arbitrary code execution or memory corruption, without requiring authentication.

Vulnerability from variot - Updated: 2025-09-13 23:28TOTOLINK NR1800X V9.1.0u.6279_B20210910 was discovered to contain an authenticated stack overflow via the command parameter in the setTracerouteCfg function. TOTOLINK of nr1800x An out-of-bounds write vulnerability exists in firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK NR1800X is a 5G NR indoor Wi-Fi and SIP CPE (broadband access equipment) launched by China's TOTOLINK Electronics. It is primarily designed for deploying NR fixed data services in homes and offices and supports 5G NR network connections. An attacker can exploit this vulnerability by submitting specially crafted requests that could cause the application to crash or execute arbitrary code in the application's context
