NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_core_module module. When asynchronous file I\/O (AIO) is enabled in certain configurations, processing a Server Side Includes (SSI) page containing \u201cinclude virtual\u201d commands may trigger a Use-After-Free (UAF) in the NGINX worker process. This may cause memory corruption or a worker process crash. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.<\/p>\n
Impact:
\nThis vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system, corrupt its memory, or possibly trigger code execution. There is no control plane exposure; this is a data plane issue only.<\/p>\n
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.<\/p>\n","protected":false},"excerpt":{"rendered":"
