Vulnerability from github – Published: 2026-04-04 00:31 – Updated: 2026-04-04 00:31

Details

Hirschmann HiSecOS devices versions prior to 05.3.03 contain a buffer overflow vulnerability in the HTTPS login interface when RADIUS authentication is enabled that allows remote attackers to crash the device or execute arbitrary code by submitting a password longer than 128 characters. Attackers can exploit improper bounds checking in password handling to overflow a fixed-size buffer and achieve denial of service or remote code execution.
