Update on Privilege-Escalation Vulnerability Notice

May 4, 2017

 

Dear Valued Customers and Partners:
 

Hikvision is honored to work with the U.S. Department of Homeland Security’s National Cybersecurity and Communications Integration Center in our ongoing cybersecurity best practice efforts.
 

We’re pleased to announce that Hikvision’s successful progress on a privilege-escalating vulnerability has been acknowledged by ICS-CERT (Industrial Control Systems Cyber Emergency Response Team). Specifically, ICS-CERT has recognized that on March 15, 2017 Hikvision released the fixed firmware version 5.4.5 to address the user privilege-escalation vulnerability.
 

What do customers need to know about the privilege-escalating vulnerability? What steps should customers take to enhance the cybersecurity of Hikvision systems?

  • Please review the March 15, 2017 notice, which outlines potential cybersecurity concerns that could arise with specific cameras under certain, fairly uncommon circumstances. To date, Hikvision is not aware of any reports of malicious activity associated with this vulnerability.

  • Hikvision always recommends a systematic, multi-step approach to enhance cybersecurity protection. To assist customers and partners, Hikvision offers a number of industry-leading cybersecurity resources. Please visit the Hikvision Security Center for more information.

  • The Hikvision Network Security Hardening Guide is a new resource for installers.

  • Hikvision also encourages customers to utilize ICS-CERT resources, including ICS-CERT Recommended Practices and ICS-CERT Defense in Depth.
     

Did ISC-CERT recommend further enhancements in future firmware upgrades?

  • ICS-CERT identified two areas of potential concern: the configuration file and “gray market” cameras.
     

Under what circumstances is there a concern with the configuration file? How will Hikvision address this concern?

  • The configuration file is encrypted and is therefore not readable, and protects users’ credentials. Also, the configuration file can only be exported by the admin account. Hikvision appreciates ICS-CERT’s comment, and will enhance the private key decryption storage method in the upcoming firmware release.
     

What is the concern with “gray market” cameras? Doesn’t Hikvision only service cameras that are purchased through authorized channels?

  • As always, Hikvision warns potential customers against purchasing from unauthorized distributors. Only authorized Hikvision USA distributors ensure customers receive the benefits of technical support, project registration, and Hikvision USA's full warranty. Click here to see the list of authorized Hikvision distributors.

  • Hikvision products purchased from an online source or unauthorized distributor may not be compatible with the North American region’s firmware and are considered to be “gray market” product. Updating the firmware from the Hikvision USA site can lead to complications in gray market cameras. Gray market cameras users should upgrade firmware through their original purchasing channel.

  • If you have any questions or concerns about the official status of your Hikvision distributor, please contact Hikvision USA Customer Service at csr.usa@hikvision.com.

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.

 

Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.

 

After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.

 

Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.

 

Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.

 

Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.

 

Downgrading

Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.

K-Series DVR upgrade instruction
The Turbo 4 Hybrid DVR K series has multiple models and across different platform and chipset. It also has similar firmware development of other recording product line; DVR K series has also introduced the GUI4.0 to ensure the series to be compatible to the newest technology available. The new database architecture is also brought into the DVR firmware v4.0 to be future proof and for better recording search experience. 
 


Database Optimization and Repair

As more affordable cameras introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.
After upgrading to v4.X, the recorder database will need to be converted and optimize. If you are experiencing issues, where playback is expected but not found, please make sure to perform "Database Rebuild" as indicated in the procedures and scenarios below.
 


Preparing the Upgrade

Before proceeding with upgrade, it is recommend exporting DVR configuration file from the DVR over the network or on to a local USB drive.

 

Action after firmware upgraded 

1. Upgrade the DVR according to the chart above. 

2. Reconfirming Channel's Recording Schedule 

    - Confirm channel's recording schedule is enable. 

    - Check if the channel is on correct recording schedule.

3. Double Check Storage Setting

    - Make sure all channel are assigned to record on its HDD group when the Storage setting is under Group Mode. 

4. Perform Database Rebuild locally. 

    • Some version above support Database Rebuild via web access - K51 and K72

    • Perform Database Rebuild regardless if system is having any database issue symptom. 

    • Database Rebuild process is average ~30 to 60min per TB. The process may still varies depends recording data.

    • After Database Rebuild - Check log to confirm Database Rebuild has went thru properly. 

    • If Database Rebuild Started and Stopped log has been log only within few minutes. Database rebuild may not has been completed properly. It is strongly recommend performing the Database Rebuild again.

    • To check log > System > Log > Information > Database Rebuild Started and Stopped.

    • If the log option is not available - access system via SSH can also obtain similar result.

5. Recording Data is still missing after database rebuild process. 

If the data has not been recorded or has been overwritten, Database rebuild process is not able retrieve those lost data. Have the system upgraded to the latest available firmware version above to prevent any future data lost is strongly recommended for all application.
