  1. ALPINE-CVE-2025-23419

    Mittel · CVSS 5.3Korrektur verfügbar

    ALPINE-CVE-2025-23419

    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.

  2. ALPINE-CVE-2024-7347

    Mittel · CVSS 4.7Korrektur verfügbar

    ALPINE-CVE-2024-7347

    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.

    ALPINE-CVE-2022-41742

    NGINX Open Source before versions 1.23.2 and 1.22.1, NGINX Open Source Subscription before versions R2 P1 and R1 P1, and NGINX Plus before versions R27 P1 and R26 P1 have a vulnerability in the module ngx_http_mp4_module that might allow a local attacker to cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted audio or video file. The issue affects only NGINX products that are built with the module ngx_http_mp4_module, when the mp4 directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger processing of a specially crafted audio or video

  6. ALPINE-CVE-2021-3618

    Hoch · CVSS 7.4Korrektur verfügbar

    ALPINE-CVE-2021-3618

    ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

    ALPINE-CVE-2021-23017

    A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact.

    ALPINE-CVE-2019-20372

    NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.

  13. ALPINE-CVE-2019-9516

    Mittel · CVSS 6.5Korrektur verfügbar

    ALPINE-CVE-2019-9516

    Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2019-9513

    Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.

  15. ALPINE-CVE-2019-9511

    Hoch · CVSS 7.5Korrektur verfügbar

    ALPINE-CVE-2019-9511

    Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

    Mittel · CVSS 6.1Korrektur verfügbar

    ALPINE-CVE-2018-16845

    nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.
