CVE-2026-60065: CWE-125 Out-of-bounds Read in F5 NGINX Plus
When NGINX Plus is configured to use the Message Queuing Telemetry Transport (MQTT) filter module (ngx_stream_mqtt_filter_module), unauthenticated attackers can send requests with conditions beyond the attacker's control to cause a heap buffer over-read in the NGINX worker process, leading to a restart. Impact: This vulnerability may allow remote unauthenticated attackers to have limited control to restart the NGINX worker process. There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read (CWE-125) in the ngx_stream_mqtt_filter_module of F5 NGINX Plus. When configured to use this MQTT filter, unauthenticated remote attackers can send specially crafted requests that trigger a heap buffer over-read, causing the NGINX worker process to restart. The vulnerability affects versions =37.0.0.1, =R36, and =R33. There is no indication of control plane compromise or data confidentiality/integrity impact. The CVSS 3.1 base score is 3.7, reflecting a low severity denial-of-service impact.
Potential Impact
The vulnerability allows remote unauthenticated attackers to cause a denial-of-service condition by restarting the NGINX worker process through a heap buffer over-read. There is no impact on confidentiality or integrity, and no control plane exposure. The disruption is limited to the data plane and results in limited availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Users should monitor F5 advisories for updates and consider disabling the MQTT filter module if feasible until a fix is available.
