VIVOTEK FD8136 Firmware

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

Vivotek FD8136 devices allow Remote Command Injection, related to BusyBox and wget. NOTE: the vendor sent a clarification on 2019-09-17 explaining that, although this CVE was first populated in July 2019, it is a historical vulnerability that does not apply to any current or recent Vivotek hardware or firmware

Vivotek FD8136 devices allow remote memory corruption and remote code execution because of a stack-based buffer overflow, related to sprintf, vlocal_buff_4326, and set_getparam.cgi. 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

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.

A remote buffer overflow vulnerability exists in the /cgi-bin/dido/setdo.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.

Buffer Overflow vulnerability in VIVOTEK INC FD8136-VVTK-0300a allows a remote attacker to execute arbitrary code via the set_getparam.cgi component

A path traversal vulnerability in the /admin/downloadMedias.cgi endpoint of VIVOTEK INC FD8136-VVTK firmware 0300a allows authenticated attackers to read any file on the device via sending a crafted request.

A stack-based buffer overflow in the motion_privacy.cgi binary in VIVOTEK FD8136 firmware FD8136-VVTK-0300a allows authenticated remote attackers to execute arbitrary code as root via an oversized n1 parameter in a POST request to the /cgi-bin/admin/setpm.cgi, /cgi-bin/admin/setmd.cgi, or /cgi-bin/admin/setmd_profile.cgi endpoint (all symlinks to the same binary). The parameter value is copied into a fixed-size 0xa4-byte stack buffer without bounds checking, overwriting the saved link register. The binary is compiled without stack canaries.

A stack-based buffer overflow in the export_language.cgi binary in VIVOTEK FD8136 firmware FD8136-VVTK-0300a allows authenticated remote attackers to execute arbitrary code as root via a crafted POST request to the /cgi-bin/admin/export_language.cgi endpoint. The handler passes the attacker-controlled Content-Length value directly to fread() as the read size into a fixed-size 0x60-byte stack buffer, overwriting the saved link register. The binary is compiled without stack canaries.
