In Totolink A3100R V5.9c.4577, multiple pages can be read by curl or Burp Suite without authentication. Additionally, admin configurations can be set without cookies.

TOTOLINK EX1200T V4.1.2cu.5215 is affected by a command injection vulnerability that can remotely execute arbitrary code.

In Totolink A3100R V5.9c.4577, "test.asp" contains an API-like function, which is not authenticated. Using this function, an attacker can configure multiple settings without authentication.

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.

TOTOLINK EX1200T V4.1.2cu.5215 contains a remote command injection vulnerability in the function setDiagnosisCfg of the file lib/cste_modules/system.so to control the ipDoamin.

totolink a3100r V5.9c.4577 is vulnerable to os command injection. The backend of a page is executing the "ping" command, and the input field does not adequately filter special symbols. This can lead to command injection attacks.

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.

TOTOLINK A3100R V4.1.2cu.5050_B20200504 and V4.1.2cu.5247_B20211129 were discovered to contain a stack overflow via the startTime and endTime parameters in the function setParentalRules. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.

In totolink a3100r V5.9c.4577, the hard-coded telnet password can be discovered from official released firmware. An attacker, who has connected to the Wi-Fi, can easily telnet into the target with root shell if the telnet is function turned on.

In TOTOLINK X6000R V9.4.0cu.1041_B20240224 in the shttpd file, the Uci_Set Str function is used without strict parameter filtering. An attacker can achieve arbitrary command execution by constructing the payload.

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.

TOTOLINK CP900L v4.1.5cu.798_B20221228 was discovered to contain a stack overflow via the password parameter in the function loginAuth

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 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.

TOTOLINK CP900L v4.1.5cu.798_B20221228 was discovered to contain a hardcoded password vulnerability in /etc/shadow.sample, which allows attackers to log in as root.

An issue in TOTOlink A3700R v.9.1.2u.6134_B20201202 allows a local attacker to execute arbitrary code via the setTracerouteCfg function.

In TOTOLINK A7000R firmware 9.1.0u.6115_B20201022, an attacker can bypass login by sending a specific request through formLoginAuth.htm.

In TOTOLINK EX1200T firmware 4.1.2cu.5215, an attacker can bypass login by sending a specific request through formLoginAuth.htm.

In TOTOLink A7100RU V7.4, A950RG V5.9, and T10 V5.9, the chroot_local_user option is enabled in the vsftpd.conf. This could lead to unauthorized access to system files, privilege escalation, or use of the compromised server as a pivot point for internal network attacks.

TOTOLINK X5000R V9.1.0cu.2415_B20250515 contains a denial-of-service vulnerability in /cgi-bin/cstecgi.cgi. The CGI reads the CONTENT_LENGTH environment variable and allocates memory using malloc (CONTENT_LENGTH + 1) without sufficient bounds checking. When lighttpd s request size limit is not enforced, a crafted large POST request can cause memory exhaustion or a segmentation fault, leading to a crash of the management CGI and loss of availability of the web interface.

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.

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.
