CVE	Date	Vulnerability	Products
CVE-2025-23419	Feb 05, 2025	Nginx TLS Session Resumption Bypass on Shared IP/Port with ClientCert Auth When multiple server blocks are configured to share the same IP address and port, an attacker can use session resumption to bypass client certificate authentication requirements on these servers. This vulnerability arises when TLS Session Tickets https://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_session_ticket_key are used and/or the SSL session cache https://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_session_cache are used in the default server and the default server is performing client certificate authentication. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.	nginx
CVE-2024-7347	Aug 14, 2024	NGINX ngx_http_mp4 overflow crash via crafted MP4 NGINX Open Source and NGINX Plus have a vulnerability in the ngx_http_mp4_module, which might allow an attacker to over-read NGINX worker memory resulting in its termination, using a specially crafted mp4 file. The issue only affects NGINX if it is built with the ngx_http_mp4_module and the mp4 directive is used in the configuration file. Additionally, the attack is possible only if an attacker can trigger the processing of a specially crafted mp4 file with the ngx_http_mp4_module. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.	nginx
CVE-2024-34161	May 29, 2024	NGINX QUIC Packet Leak: Undisclosed QUIC Causes Worker Process Memory Leak When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module and the network infrastructure supports a Maximum Transmission Unit (MTU) of 4096 or greater without fragmentation, undisclosed QUIC packets can cause NGINX worker processes to leak previously freed memory.	nginx
CVE-2024-35200	May 29, 2024	NGINX: Worker Crashes via Undisclosed HTTP/3 QUIC Requests When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 requests can cause NGINX worker processes to terminate.	nginx
CVE-2024-31079	May 29, 2024	NGINX HTTP/3 QUIC Module Process Termination via Undisclosed Requests When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 requests can cause NGINX worker processes to terminate or cause other potential impact. This attack requires that a request be specifically timed during the connection draining process, which the attacker has no visibility and limited influence over.	nginx
CVE-2024-24989	Feb 14, 2024	NGINX QUIC Crash via Undisclosed HTTP/3 Requests (CVE-2024-24989) When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed requests can cause NGINX worker processes to terminate. Note: The HTTP/3 QUIC module is not enabled by default and is considered experimental. For more information, refer to Support for QUIC and HTTP/3 https://nginx.org/en/docs/quic.html . NOTE: Software versions which have reached End of Technical Support (EoTS) are not evaluated	nginx
CVE-2024-24990	Feb 14, 2024	NGINX HTTP/3 QUIC Module Crashes Workers on Undisclosed Requests When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed requests can cause NGINX worker processes to terminate. Note: The HTTP/3 QUIC module is not enabled by default and is considered experimental. For more information, refer to Support for QUIC and HTTP/3 https://nginx.org/en/docs/quic.html .
