SIPLUS NET variants) (All versions < V2.1). Affected devices contain a message protection bypass vulnerability due to certain properties in the calculation used for integrity protection. This could allow an attacker in a Man-in-the-Middle position to modify network traffic sent on port 102/tcp to the affected devices.
Weakness Type
Use of a Broken or Risky Cryptographic Algorithm
The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the exposure of sensitive information. The use of a non-standard algorithm is dangerous because a determined attacker may be able to break the algorithm and compromise whatever data has been protected. Well-known techniques may exist to break the algorithm.
