Vulnerabilities

A post-authentication remote buffer overflow vulnerability exists in the /cgi-bin/admin/eventtask.cgi endpoint of the admin interface of Vivotek FD8136 cameras running firmware version FD8136-VVTK-0300a. This flaw allows an authenticated attacker to execute arbitrary code as root on the device remotely.

Vivotek IP7137 camera with firmware version 0200a by default dos not require to provide any password when logging in as an administrator. While it is possible to set up such a password, a user is not informed about such a need. The vendor has not replied to the CNA. Possibly all firmware versions are affected. Since the product has met End-Of-Life phase, a fix is not expected to be released.

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability classified as critical has been found in Vivotek IB8367A VVTK-0100b. Affected is the function getenv of the file upload_file.cgi. The manipulation of the argument QUERY_STRING leads to command injection. It is possible to launch the attack remotely. The identifier of this vulnerability is VDB-273528. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the affected release tree is end-of-life.

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in Vivotek SD9364 VVTK-0103f. It has been declared as critical. This vulnerability affects the function read of the component httpd. The manipulation of the argument Content-Length leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-273526 is the identifier assigned to this vulnerability. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the affected release tree is end-of-life.

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in Vivotek CC8160 VVTK-0100d and classified as critical. Affected by this issue is the function read of the component httpd. The manipulation of the argument Content-Length leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-273524. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the affected release tree is end-of-life.

An issue in vivotek Network Camera v.FD8166A-VVTK-0204j allows a remote attacker to execute arbitrary code via a crafted payload to the upload_file.cgi component.

VIVOTEK Network Cameras before XXXXX-VVTK-2.2002.xx.01x (and before XXXXX-VVTK-0XXXX_Beta2) allows an authenticated user to upload and execute a script (with resultant execution of OS commands). For example, this affects IT9388-HT devices.

VIVOTEK IP Camera devices with firmware before 0x20x allow a denial of service via a crafted HTTP header.

VIVOTEK IP Camera devices with firmware before 0x20x have a stack-based buffer overflow via a crafted HTTP header.

Vivotek FD8136 devices allow Remote Command Injection, aka "another command injection vulnerability in our target device," a different issue than CVE-2018-14494. NOTE: The vendor has disputed this as a vulnerability and states that the issue does not cause a web server crash or have any other affect on it's performance

Cross-site scripting in syslog.html in VIVOTEK Network Camera Series products with firmware 0x06x to 0x08x allows remote attackers to execute arbitrary JavaScript code via an HTTP Referer Header.

VIVOTEK FD8177 devices before XXXXXX-VVTK-xx06a allow remote attackers to execute arbitrary code (issue 2 of 2) via eventscript.cgi.

Various VIVOTEK FD8*, FD9*, FE9*, IB8*, IB9*, IP9*, IZ9*, MS9*, SD9*, and other devices before XXXXXX-VVTK-xx06a allow remote attackers to execute arbitrary code.

'/cgi-bin/admin/testserver.cgi' of the web service in most of the VIVOTEK Network Cameras is vulnerable to shell command injection, which allows remote attackers to execute any shell command as root via a crafted HTTP request. This vulnerability is already verified on VIVOTEK Network Camera IB8369/FD8164/FD816BA; most others have similar firmware that may be affected. An attack uses shell metacharacters in the senderemail parameter.
