Technical details
An out-of-bounds read vulnerability exists in the SNMP processing component of MDK-Middleware versions 8.0.0 through 8.3.0. The vulnerability is pre-authentication and requires only network access to send a crafted SNMP packet; no user interaction or prior authentication is needed. An attacker can read adjacent memory contents or crash the device, though the specific data exposed depends on the application's memory layout.
