Saia Burgess Controls (SBC) PCD through 2022-05-06 allows Authentication bypass. According to FSCT-2022-0062, there is a Saia Burgess Controls (SBC) PCD S-Bus authentication bypass issue. The affected components are characterized as: S-Bus (5050/UDP) authentication. The potential impact is: Authentication bypass. The Saia Burgess Controls (SBC) PCD controllers utilize the S-Bus protocol (5050/UDP) for a variety of engineering purposes. It is possible to configure a password in order to restrict access to sensitive engineering functionality. Authentication functions on the basis of a MAC/IP whitelist with inactivity timeout to which an authenticated client's MAC/IP is stored. UDP traffic can be spoofed to bypass the whitelist-based access control. Since UDP is stateless, an attacker capable of passively observing traffic can spoof arbitrary messages using the MAC/IP of an authenticated client. This allows the attacker access to sensitive engineering functionality such as uploading/downloading control logic and manipulating controller configuration.

ICSA-22-207-03 — Honeywell Saia Burgess PG5 PCD

The affected product uses the S-Bus protocol with authentication functions that can be controlled by the client MAC and IP. Because UDP is stateless, an attacker that can observe traffic can also spoof the MAC and IP of an authenticated client and manipulate the controller configuration.CVE-2022-30319 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been assigned; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L). The affected product uses the S-Bus write byte message to a specific address and supplies a hashed version of the password. The hashing algorithm is based on CRC-16 and, as such, is not cryptographically secure.CVE-2022-30320 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been assigned; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L).
