Technical details
An out-of-bounds read (CWE-125) exists in the ngx_stream_mqtt_filter_module of NGINX Plus. The vulnerability is triggered when the module is configured and an unauthenticated attacker sends specifically crafted MQTT requests that create conditions leading to a heap buffer over-read. This results in the termination and subsequent restart of the NGINX worker process, impacting availability. The attack requires the MQTT filter to be active and has a high attack complexity as the conditions are partially beyond the attacker's direct control. Patches are available in versions 37.0.3.1 and R36 P7.
Affected products
- F5 NGINX Plus 37.0.0.1 to 37.0.3.1, R36 before R36 P7, R33 and later
