CVE-2021-27710totolinka720r_firmware+15y ago14-04-2021 17:07

Command Injection in TOTOLINK X5000R router with firmware v9.1.0u.6118_B20201102, and TOTOLINK A720R router with firmware v4.1.5cu.470_B20200911 allows remote attackers to execute arbitrary OS commands by sending a modified HTTP request. This occurs because the function executes glibc's system function with untrusted input. In the function, "ip" parameter is directly passed to the attacker, allowing them to control the "ip" field to attack the OS.CVE-2021-27708totolinka720r_firmware+15y ago14-04-2021 15:01

A vulnerability was found in TOTOLINK X5000R 9.1.0cu.2415_B20250515. This affects the function sub_410C34 of the file /cgi-bin/cstecgi.cgi. Performing manipulation of the argument pid results in command injection. Remote exploitation of the attack is possible. The exploit has been made public and could be used.CVE-2025-14586totolinkx5000r_firmware10mo ago13-12-2025 06:32

A vulnerability was determined in TOTOLINK X5000R 9.1.0cu.2089_B20211224. Affected by this issue is the function snprintf of the file /cgi-bin/cstecgi.cgi?action=exportOvpn&type=user. This manipulation of the argument User causes os command injection. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized.CVE-2025-25604totolinkx5000r_firmware1y ago21-02-2025 00:00

Totolink X5000R V9.1.0u.6369_B20230113 is vulnerable to command injection via the vif_disable function in mtkwifi.lua.CVE-2025-25605totolinkx5000r_firmware1y ago21-02-2025 00:00

Totolink X5000R V9.1.0u.6369_B20230113 is vulnerable to command injection via the apcli_wps_gen_pincode function in mtkwifi.lua.CVE-2025-67445totolinkx5000r_firmware7mo ago24-02-2026 00:00

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.CVE-2025-70329totolinkx5000r_firmware8mo ago23-02-2026 00:00

TOTOLink X5000R v9.1.0cu_2415_B20250515 contains an OS command injection vulnerability in the setIptvCfg handler of the /usr/sbin/lighttpd executable. The vlanVidLan1 (and other vlanVidLanX) parameters are retrieved via Uci_Get_Str and passed to the CsteSystem function without adequate validation or filtering. This allows an authenticated attacker to execute arbitrary shell commands with root privileges by injecting shell metacharacters into the affected parameters.CVE-2025-70327totolinkx5000r_firmware8mo ago23-02-2026 00:00

TOTOLINK X5000R v9.1.0cu_2415_B20250515 contains an argument injection vulnerability in the setDiagnosisCfg handler of the /usr/sbin/lighttpd executable. The ip parameter is retrieved via websGetVar and passed to a ping command through CsteSystem without validating if the input starts with a hyphen (-). This allows remote authenticated attackers to inject arbitrary command-line options into the ping utility, potentially leading to a Denial of Service (DoS) by causing excessive resource consumption or prolonged execution.CVE-2022-26213totolinkx5000r_firmware4y ago15-03-2022 21:56
