CVE-2025-60686 1 Totolink 6 A720r, A720r Firmware, Lr1200gb and 3 more 2025-11-19 5.1 Medium
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.
CVE-2025-60687 1 Totolink 2 Lr1200gb, Lr1200gb Firmware 2025-11-19 6.5 Medium
An unauthenticated command injection vulnerability exists in the ToToLink LR1200GB Router firmware V9.1.0u.6619_B20230130 within the cstecgi.cgi binary (sub_41EC68 function). The binary reads the "imei" parameter from a web request and verifies only that it is 15 characters long. The parameter is then directly inserted into a system command using sprintf() and executed with system(). Maliciously crafted IMEI input can execute arbitrary commands on the router without authentication.
CVE-2025-60688 1 Totolink 4 Lr1200gb, Lr1200gb Firmware, Nr1800x and 1 more 2025-11-19 6.5 Medium
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.
CVE-2025-60699 1 Totolink 2 A950rg, A950rg Firmware 2025-11-18 6.5 Medium
A buffer overflow vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the `global.so` binary. The `getSaveConfig` function retrieves the `http_host` parameter from user input via `websGetVar` and copies it into a fixed-size stack buffer (`v13`) using `strcpy()` without performing any length checks. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted HTTP request to the router's web interface, potentially leading to arbitrary code execution.
CVE-2025-60702 1 Totolink 2 A950rg, A950rg Firmware 2025-11-18 6.5 Medium
A command injection vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the `system.so` binary. The `setDiagnosisCfg` function retrieves the `ipDoamin` parameter from user input via `websGetVar` and concatenates it directly into a `ping` system command executed via `CsteSystem()` without any sanitization. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.
CVE-2025-60685 1 Totolink 2 A720r, A720r Firmware 2025-11-18 5.1 Medium
A stack buffer overflow exists in the ToToLink A720R Router firmware V4.1.5cu.614_B20230630 within the sysconf binary (sub_401EE0 function). The binary reads the /proc/stat file using fgets() into a local buffer and subsequently parses the line using sscanf() into a single-byte variable with the %s format specifier. Maliciously crafted /proc/stat content can overwrite adjacent stack memory, potentially allowing an attacker with filesystem write privileges to execute arbitrary code on the device.
CVE-2025-60682 1 Totolink 2 A720r, A720r Firmware 2025-11-17 6.5 Medium
A command injection vulnerability exists in the ToToLink A720R Router firmware V4.1.5cu.614_B20230630 within the cloudupdate_check binary, specifically in the sub_402414 function that handles cloud update parameters. User-supplied 'magicid' and 'url' values are directly concatenated into shell commands and executed via system() without any sanitization or escaping. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device.
CVE-2025-60683 1 Totolink 2 A720r, A720r Firmware 2025-11-17 6.5 Medium
A command injection vulnerability exists in the ToToLink A720R Router firmware V4.1.5cu.614_B20230630 within the sysconf binary, specifically in the sub_40BFA4 function that handles network interface reinitialization from '/var/system/linux_vlan_reinit'. Input is only partially validated by checking the prefix of interface names, and is concatenated into shell commands executed via system() without escaping. An attacker with write access to this file can execute arbitrary commands on the device.
CVE-2025-63153 1 Totolink 2 A7000r, A7000r Firmware 2025-11-17 7.5 High

TOTOLink A7000R V9.1.0u.6115_B20201022 was discovered to contain a stack overflow in the addEffect parameter of the urldecode function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.
CVE-2025-60684 1 Totolink 2 Lr1200gb, Nr1800x 2025-11-14 6.5 Medium
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.
