According to FSCT-2022-0063, there is a Saia Burgess Controls (SBC) PCD S-Bus weak credential hashing scheme 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 is done by using the S-Bus 'write byte' message to a specific address and supplying a hashed version of the password. The hashing algorithm used is based on CRC-16 and as such not cryptographically secure. An insecure hashing algorithm is used. An attacker capable of passively observing traffic can intercept the hashed credentials and trivially find collisions allowing for authentication without having to bruteforce a keyspace defined by the actual strength of the password. This allows the attacker access to sensitive engineering functionality such as uploading/downloading control logic and manipulating controller configuration."}, {"lang": "es", "value": "Saia Burgess Controls (SBC) PCD versiones hasta 06-05-2022, usa un algoritmo criptogr\u00e1fico roto o arriesgado.

Los controladores PCD de Saia Burgess Controls (SBC) usan el protocolo S-Bus (5050/UDP) para diversos fines de ingenier\u00eda. Es posible configurar una contrase\u00f1a para restringir el acceso a la funcionalidad de ingenier\u00eda confidencial.

Un atacante capaz de observar pasivamente el tr\u00e1fico puede interceptar las credenciales con hash y encontrar trivialmente colisiones que permitan la autenticaci\u00f3n sin tener que forzar un espacio de claves definido por la fuerza real de la contrase\u00f1a.
