| A 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. |
| A 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. |
| A 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. |
| A vulnerability was found in Totolink NR1800X 9.1.0u.6279_B20210910 and classified as critical. Affected by this issue is the function loginAuth of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument password leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-249854 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. |
