3.2.1 SESSION FIXATION CWE-384
Some access control products are vulnerable to a session hijacking attack because the product does not update the session ID after a user successfully logs in. To exploit the vulnerability, attackers have to request the session ID at the same time a valid user logs in, and gain device operation permissions by forging the IP and session ID of an authenticated user.
CVE-2023-28809 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H).
3.2.2 IMPROPER ACCESS CONTROL CWE-284
Some access control/intercom products have unauthorized modification of device network configuration vulnerabilities. Attackers can modify device network configuration by sending specific data packets to the vulnerable interface within the same local network.
CVE-2023-28810 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been assigned; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).
These vulnerabilities were reported to HSRC by Andres Hinnosaar with the support of NATO CCDCOE and Peter Szot from Skylight Cyber. Hikvision reported these vulnerabilities to CISA.
Hikvision recommends users download patches/updates to mitigate these vulnerabilities. The upgrade can be downloaded from the Hikvision official website.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
