## Technical details

This vulnerability involves a replay attack against the SPC Connect Pro software that manages the SPC5300.000 Main Board. The software accepts replayed application-layer payloads injected into active TCP sessions without proper validation or cryptographic protection, allowing an attacker with network or physical access to inject previously captured network traffic. An attacker with physical proximity to the network can intercept and replay legitimate TCP packets to cause a denial of service condition, disrupting the access control system. Patches or fixes are not mentioned in the available advisory information.
