SV3C L-SERIES HD CAMERA V2.3.4.2103-S50-NTD-B20170508B and V2.3.4.2103-S50-NTD-B20170823B devices allow OS Command Injection.

An attacker with remote access to the SV3C HD Camera (L-SERIES V2.3.4.2103-S50-NTD-B20170508B and V2.3.4.2103-S50-NTD-B20170823B) web interface can disclose information about the camera including all password sets set within the camera. This information can then be used to gain access to the web interface.

The SV3C HD Camera (L-SERIES V2.3.4.2103-S50-NTD-B20170508B) does not perform proper validation on user-supplied input and is vulnerable to cross-site scripting attacks. If proper authorization was implemented, this vulnerability could be leveraged to perform actions on behalf of another user or the administrator.

An attacker with remote access to the SV3C HD Camera (L-SERIES V2.3.4.2103-S50-NTD-B20170508B and V2.3.4.2103-S50-NTD-B20170823B) web interface can disclose information about the camera including camera hardware, wireless network, and local area network information.
