CVE-2026-61517
High · 7.2
CWE-78 Sep 8, 2026
Netis NX10 OS Command Injection via Ping Diagnostic Handler
Netis NX10 firmware V4.0.1.5808 and V3.0.0.4142 contain an OS command injection vulnerability in the ping diagnostic handler that allows authenticated administrators to execute arbitrary shell commands as root by injecting into the IpAddr parameter. The parameter is interpolated directly into a shell command executed through system() with an incomplete denylist that only blocks spaces, pipes, semicolons, and ampersands, leaving command substitution and alternate field separator expansion available for exploitation.

CWE-522 Sep 8, 2026
Netis NX10 Credential Disclosure via sysinfo Diagnostic Endpoint
Netis NX10 firmware V4.0.1.5808 and V3.0.0.4142 contain an information disclosure vulnerability that allows unauthenticated attackers to retrieve the administrator password by sending a request to the sysinfo action in the web management interface without a valid session. Attackers can replay the exposed credential against the login handler to establish a fully authenticated administrator session on the device.
CVE-2026-76071
Critical · 9.8
CWE-121 Aug 24, 2026
Netis NC63 V3.0.0.3327 Stack Buffer Overflow via destHost Parameter
Netis NC63 firmware through V3.0.0.3327 contains a stack-based buffer overflow vulnerability that allows unauthenticated remote attackers to overwrite saved stack state by supplying an oversized destHost parameter to the ipFilterList=mod action in netis.cgi. Attackers can exploit widthless sscanf conversions that copy user-supplied input into fixed-size stack buffers before authentication is verified, achieving remote code execution as root due to the Boa web server executing the CGI environment with root privileges.
CVE-2026-76070
Critical · 9.8
CWE-121 Aug 24, 2026
Netis NC63 V3.0.0.3327 Stack Buffer Overflow via Login Password Parameter
Netis NC63 firmware through V3.0.0.3327 contains a stack-based buffer overflow vulnerability that allows unauthenticated remote attackers to overwrite saved stack state by submitting an oversized Base64-encoded password to the login handler in /bin/netis.cgi. Attackers can exploit the custom Base64 decoder's lack of output length validation against the fixed-size stack buffer to achieve remote code execution with root privileges, as the Boa web server executes the CGI environment as root.
CVE-2026-73673
High · 8.8
CWE-306 Aug 14, 2026
Netis NC63 V3.0.0.3327 Unauthenticated Firmware Update with Missing Cryptographic Firmware Authentication
Netis NC63 router firmware V3.0.0.3327 contains an unauthenticated firmware update vulnerability that allows unauthenticated attackers to submit unsigned firmware images by exploiting a missing authentication enforcement flaw in the Boa web server and netis.cgi CGI dispatcher. Attackers can send a multipart POST request to /cgi-bin/upload_fw.cgi without a valid session cookie, bypassing authentication because Boa grants access to any path containing '.cgi' regardless of cookie validation, and netis.cgi reads but does not enforce the authentication state before invoking the firmware update handler, which accepts images validated only by a forgeable additive checksum and static product strings rather than a cryptographic signature, potentially enabling persistent router compromise.
CVE-2020-37093
High · 7.5
CWE-201 Feb 3, 2026
Netis E1+ 1.2.32533 - Unauthenticated WiFi Password Leak
Netis E1+ 1.2.32533 contains an information disclosure vulnerability that allows unauthenticated attackers to retrieve WiFi passwords through the netcore_get.cgi endpoint. Attackers can send a GET request to the endpoint to extract sensitive network credentials including SSID and WiFi passwords in plain text.
CVE-2020-37092
High · 7.5
CWE-798 Feb 3, 2026
Netis E1+ 1.2.32533 - Backdoor Account (root)
Netis E1+ version 1.2.32533 contains a hardcoded root account vulnerability that allows unauthenticated attackers to access the device with predefined credentials. Attackers can leverage the embedded root account with a crackable password to gain full administrative access to the network device.
CVE-2018-25125
High · 8.7
CWE-120 Nov 14, 2025
Netis DL4322D RTK 2.1.1 FTP Service DoS
Netis ADSL Router DL4322D firmware RTK 2.1.1 contains a buffer overflow vulnerability in the embedded FTP service that allows an authenticated remote user to trigger a denial of service. After logging in to the FTP service, sending an FTP command such as ABOR with an excessively long argument causes the service, and in practice the router, to crash or become unresponsive, resulting in a loss of availability for the device and connected users.
CVE-2019-19356

KEV High · 62 Public exploit CWE-78 Feb 7, 2020
Netis WF2419 Devices Remote Code Execution Vulnerability
Netis WF2419 is vulnerable to authenticated Remote Code Execution (RCE) as root through the router Web management page. The vulnerability has been found in firmware version V1.2.31805 and V2.2.36123. After one is connected to this page, it is possible to execute system commands as root through the tracert diagnostic tool because of lack of user input sanitizing.
