https://notcve.org/view.php?id=CVE-2021-2351
Vulnerability in the Advanced Networking Option component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1 and 19c. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise Advanced Networking Option. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Advanced Networking Option, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Advanced Networking Option. • http://packetstormsecurity.com/files/165255/Oracle-Database-Protection-Mechanism-Bypass.html http://packetstormsecurity.com/files/165258/Oracle-Database-Weak-NNE-Integrity-Key-Derivation.html http://seclists.org/fulldisclosure/2021/Dec/19 http://seclists.org/fulldisclosure/2021/Dec/20 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https://www.oracle.com/security-alerts/cpujan2023.html https://www.oracle.com/security-alerts/cpujul2021.html https:&# • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-384: Session Fixation •
CVSS: 5.3EPSS: 10%CPEs: 42EXPL: 0CVE-2021-33037 – Incorrect Transfer-Encoding handling with HTTP/1.0
https://notcve.org/view.php?id=CVE-2021-33037
Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding. Apache Tomcat versiones 10.0.0-M1 hasta 10.0.6, versiones 9.0.0.M1 hasta 9.0.46 y versiones 8.5.0 hasta 8.5.66, no analizaban correctamente el encabezado de petición HTTP transfer-encoding en algunas circunstancias, conllevando a la posibilidad de contrabando de peticiones cuando se usaba con un proxy inverso. Específicamente: - Tomcat ignoraba incorrectamente el encabezado de codificación de transferencia si el cliente declaraba que sólo aceptaría una respuesta HTTP/1.0; - Tomcat honraba la codificación de identificación; y - Tomcat no se aseguraba de que, si estaba presente, la codificación en trozos fuera la codificación final • https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r290aee55b72811fd19e75ac80f6143716c079170c5671b96932ed44b%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r40f921575aee8d7d34e53182f862c45cbb8f3d898c9d4e865c2ec262%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r612a79269b0d5e5780c62dfd34286a8037232fec0bc6f1a7e60c9381%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/rc6ef52453bb996a98cb45442871a1db56b7c349939e45d829bf9ae37%40%3Ccommits.tomee.apache.org%3E https:/ • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

CVSS: 7.5EPSS: 3%CPEs: 11EXPL: 0CVE-2021-31618 – NULL pointer dereference on specially crafted HTTP/2 request
https://notcve.org/view.php?id=CVE-2021-31618
Apache HTTP Server protocol handler for the HTTP/2 protocol checks received request headers against the size limitations as configured for the server and used for the HTTP/1 protocol as well. On violation of these restrictions and HTTP response is sent to the client with a status code indicating why the request was rejected. This rejection response was not fully initialised in the HTTP/2 protocol handler if the offending header was the very first one received or appeared in a a footer. This led to a NULL pointer dereference on initialised memory, crashing reliably the child process. Since such a triggering HTTP/2 request is easy to craft and submit, this can be exploited to DoS the server. • http://httpd.apache.org/security/vulnerabilities_24.html http://www.openwall.com/lists/oss-security/2021/06/10/9 http://www.openwall.com/lists/oss-security/2024/03/13/2 https://lists.apache.org/thread.html/r14b66ef0f4f569fd515a3f96cd4eb58bd9a8ff525cc326bb0359664f%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r783b6558abf3305b17ea462bed4bd66d82866438999bf38cef6d11d1%40%3Ccvs.httpd.apache.org%3E https://lists.debian.org/debian-lts-announce/2021/07/msg00006.html https://lists.fedoraproject.org/archive • CWE-476: NULL Pointer Dereference •
