Vendor: Hikvision
Equipment: Cameras
Vulnerabilities: Improper Authentication, Password in Configuration File
Hikvision reports that the following cameras and versions are affected:
Successful exploitation of these vulnerabilities could lead to a malicious attacker escalating his or her privileges or assuming the identity of an authenticated user and obtaining sensitive data.
Hikvision has released updates to mitigate the improper authentication vulnerability in cameras sold through authorized distributers. Hikvision has not mitigated the password in configuration file vulnerability.
However, Hikvision is aware of so-called “grey market” cameras which are sold via unauthorized channels. These cameras often use unauthorized firmware created by sources outside of Hikvision. In the case of these “grey market” devices, updating the firmware may result in converting the camera’s interface back to its original state. Users of “grey market” cameras who cannot update due to this unauthorized firmware will still be susceptible to these vulnerabilities.
In the Hikvision Unauthorized Distributors Notice, Hikvision encourages users to use devices sold by authorized distributers rather than so-called “grey market” devices. Hikvision’s Unauthorized Distributors Notice can be found at the following location:
http://www.hikvision.com/us/about.aspx?stat=1&c_kind=293&c_kind2=10631
North American models of Hikvision cameras which can be fixed and their updated firmware versions are listed below:
These updates are available for download at the following location:

More information can be found by visiting Hikvision’s Vulnerability Notice:
<http://www.hikvision.com/us/about_10807.html>
For Chinese-language domestic cameras, Hikvision also provides on-site tours or remote support in addition to the updated firmware listed above.
Hikvision also states that device models and firmware upgrade procedures may differ between regions. These policies will be communicated to users through Hikvision.
NCCIC/ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
In addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:
No known public exploits specifically target these vulnerabilities.
The improper authentication vulnerability occurs when an application does not adequately or correctly authenticate users. This may allow a malicious user to escalate his or her privileges on the system and gain access to sensitive information.
CVE-2017-7921 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
The password in configuration file vulnerability could allow a malicious user to escalate privileges or assume the identity of another user and access sensitive information.
CVE-2017-7923 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
