Vulnerability from github – Published: 2024-03-01 21:31 – Updated: 2024-03-01 21:31

Details

Industrial Control Systems Network Protocol Parsers (ICSNPP) - Ethercat Zeek Plugin versions d78dda6 and prior are vulnerable to out-of-bounds read during the process of analyzing a specific Ethercat packet. This could allow an attacker to crash the Zeek process and leak some information in memory.

Severity

8.2 (High)
