  1. 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-2025-67445
  2. 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-2025-70327
  3. 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-2025-70329
  4. 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-2025-14586
  5. Unauthenticated Telnet enablement via cstecgi.cgi (auth bypass) leading to unauthenticated root login with a blank password on factory/reset X5000R V9.1.0u.6369_B20230113 (arbitrary command execution). Earlier versions that share the same implementation, may also be affected.•CVE-2025-13184
