CVE-2024-41798 (GCVE-0-2024-41798)

Vulnerability from cvelistv5 – Published: 2024-10-08 08:40 – Updated: 2024-10-08 14:06

Summary

A vulnerability has been identified in SENTRON 7KM PAC3200 (All versions). Affected devices only provide a 4-digit PIN to protect from administrative access via Modbus TCP interface. Attackers with access to the Modbus TCP interface could easily bypass this protection by brute-force attacks or by sniffing the Modbus clear text communication.
