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.

The authentication mechanism for a specific feature in the EasyShare module contains a vulnerability. If specific conditions are met on a local network, it can cause data leakage

Insufficient protection mechanisms in the Health Module may lead to partial information disclosure.

The SmartRemote module has insufficient restrictions on loading URLs, which may lead to some information leakage.

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.

The framework service handles pendingIntent incorrectly, allowing a malicious application with certain privileges to perform privileged actions.

Vivoh Webinar Manager before 3.6.3.0 has improper API authentication. When a user logs in to the administration configuration web portlet, a VIVOH_AUTH cookie is assigned so that they can be uniquely identified. Certain APIs can be successfully executed without proper authentication. This can let an attacker impersonate as victim and make state changing requests on their behalf.

The attacker can access the sensitive information stored within the jovi Smart Scene module by entering carefully constructed commands without requesting permission.

The appstore before 8.12.0.0 exposes some of its components, and the attacker can cause remote download and install apps through carefully constructed parameters.

The frame touch module does not make validity judgments on parameter lengths when processing specific parameters,which caused out of the boundary when memory access.The vulnerability eventually leads to a local DOS on the device.

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

The Vivo V7 Android device with a build fingerprint of vivo/1718/1718:7.1.2/N2G47H/compil11021857:user/release-keys contains a platform app with a package name of com.vivo.smartshot (versionCode=1, versionName=3.0.0). This app contains an exported service named com.vivo.smartshot.ui.service.ScreenRecordService that will record the screen for 60 minutes and write the mp4 file to a location of the user's choosing. Normally, a recording notification will be visible to the user, but we discovered an approach to make it mostly transparent to the user by quickly removing a notification and floating icon. The user can see a floating icon and notification appear and disappear quickly due to quickly stopping and restarting the service with different parameters that do not interfere with the ongoing screen recording. The screen recording lasts for 60 minutes and can be written directly to the attacking app's private directory.

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.

The Vivo V7 Android device with a build fingerprint of vivo/1718/1718:7.1.2/N2G47H/compil11021857:user/release-keys contains a platform app with a package name of com.vivo.bsptest (versionCode=1, versionName=1.0) containing an exported activity app component named com.vivo.bsptest.BSPTestActivity that allows any app co-located on the device to initiate the writing of the logcat log, bluetooth log, and kernel log to external storage. When logging is enabled, there is a notification in the status bar, so it is not completely transparent to the user. The user can cancel the logging, but it can be re-enabled since the app with a package name of com.vivo.bsptest cannot be disabled. The writing of these logs can be initiated by an app co-located on the device, although the READ_EXTERNAL_STORAGE permission is necessary to for an app to access the log files.

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.

Vivo modems allow remote attackers to obtain sensitive information by reading the index.cgi?page=wifi HTML source code, as demonstrated by ssid and psk_wepkey fields.

'/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.
