CVE-2017-17704
7.4 · HIGHOverview
CVE-2017-17704 is a high-severity vulnerability affecting swhouse istar_ultra_firmware. It was published on December 31, 2017 and has a CVSS 3.0 base score of 7.4 (HIGH).
This vulnerability has a CVSS 3.0 base score of 7.4, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
A door-unlocking issue was discovered on Software House iStar Ultra devices through 6.5.2.20569 when used in conjunction with the IP-ACM Ethernet Door Module. The communications between the IP-ACM and the iStar Ultra is encrypted using a fixed AES key and IV. Each message is encrypted in CBC mode and restarts with the fixed IV, leading to replay attacks of entire messages. There is no authentication of messages beyond the use of the fixed AES key, so message forgery is also possible.
Remediation
Check the references section for vendor advisories and patches from swhouse. Update istar_ultra_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
