CVSS: 7.5EPSS: 83%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
CVSS: 9.1EPSS: 0%CPEs: 24EXPL: 0CVE-2022-22721 – core: Possible buffer overflow with very large or unlimited LimitXMLRequestBody
https://notcve.org/view.php?id=CVE-2022-22721
If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier. Si LimitXMLRequestBody está configurado para permitir cuerpos de petición de más de 350 MB (por defecto 1M) en sistemas de 32 bits, es producido un desbordamiento de enteros que causa posteriormente escrituras fuera de límites. Este problema afecta a Apache HTTP Server 2.4.52 y anteriores A flaw was found in httpd, where it incorrectly limits the value of the LimitXMLRequestBody option. This issue can lead to an integer overflow and later causes an out-of-bounds write. • http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2022/03/14/2 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.debian.org/debian-lts-announce/2022/03/msg00033.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RGWILBORT67SHMSLYSQZG2NMXGCMPUZO https://lists.fedoraproject.org/archives/list/package • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-44224
A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). Un URI diseñado que es enviado a httpd configurado como proxy directo (ProxyRequests on) puede causar un fallo (desreferencia de puntero NULL) o, en el caso de configuraciones que mezclan declaraciones de proxy directo e inverso, puede permitir que las peticiones se dirijan a un endpoint de socket de dominio Unix declarado (Server Side Request Forgery). Este problema afecta a Apache HTTP Server versiones 2.4.7 hasta 2.4.51 (incluyéndola) There's a null pointer dereference and server-side request forgery flaw in httpd's mod_proxy module, when it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket requests. • http://httpd.apache.org/security/vulnerabilities_24.html http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2021/12/20/3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BFSWOH4X77CV7AH7C4RMHUBDWKQDL4YH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RGWILBORT67SHMSLYSQZG2NMXGCMPUZO https:// • CWE-476: NULL Pointer Dereference CWE-918: Server-Side Request Forgery (SSRF) •
