CVSS: 5.8EPSS: 0%CPEs: 25EXPL: 0CVE-2019-17569 – tomcat: Regression in handling of Transfer-Encoding header allows for HTTP request smuggling
https://notcve.org/view.php?id=CVE-2019-17569
The refactoring present in Apache Tomcat 9.0.28 to 9.0.30, 8.5.48 to 8.5.50 and 7.0.98 to 7.0.99 introduced a regression. The result of the regression was that invalid Transfer-Encoding headers were incorrectly processed leading to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely. La refactorización presente en Apache Tomcat versiones 9.0.28 hasta 9.0.30, versiones 8.5.48 hasta 8.5.50 y versiones 7.0.98 hasta 7.0.99, introdujo una regresión. El resultado de la regresión fue que los encabezados Transfer-Encoding no válidos fueron procesados incorrectamente, conllevando a una posibilidad de Tráfico No Autorizado de Peticiones HTTP si Tomcat se encontraba detrás de un proxy inverso que manejaba incorrectamente el encabezado Transfer-Encoding no válido de una manera particular. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00025.html https://lists.apache.org/thread.html/r7bc994c965a34876bd94d5ff15b4e1e30b6220a15eb9b47c81915b78%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r88def002c5c78534674ca67472e035099fbe088813d50062094a1390%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/rc31cbabb46cdc58bbdd8519a8f64b6236b2635a3922bbeba0f0e3743%40%3Ccommits.tomee.apache.org%3E https://lists.debian.org/debian-lts-announce/2020/03/msg00006.html https://security.netapp.com/advisory&# • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 7.5EPSS: 0%CPEs: 16EXPL: 0CVE-2019-17563 – tomcat: Session fixation when using FORM authentication
https://notcve.org/view.php?id=CVE-2019-17563
When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability. Cuando se usa la autenticación FORM con Apache Tomcat 9.0.0.M1 hasta 9.0.29, 8.5.0 hasta 8.5.49 y 7.0.0 hasta 7.0.98, había una ventana estrecha donde un atacante podía llevar a cabo un ataque de fijación de sesión. La ventana fue considerada demasiado estrecha para que una explotación sea práctica, pero, por precaución, este problema ha sido tratado como una vulnerabilidad de seguridad. It was found that tomcat's FORM authentication allowed a very small period in which an attacker could possibly force a victim to use a valid user session, or Session Fixation. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00013.html https://lists.apache.org/thread.html/8b4c1db8300117b28a0f3f743c0b9e3f964687a690cdf9662a884bbd%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/r3bbb800a816d0a51eccc5a228c58736960a9fffafa581a225834d97d%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/r48c1444845fe15a823e1374674bfc297d5008a5453788099ea14caf0%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/r6ccee4e849bc77df0840c7f853f6bd09d426f6741247da2b7429d5d9%40%3Cdev.tomcat.apache.org%3E https • CWE-384: Session Fixation •

https://notcve.org/view.php?id=CVE-2019-17571
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17. Incluido en Log4j versión 1.2 existe una clase SocketServer que es vulnerable a la deserialización de datos no confiables, que pueden ser explotada para ejecutar código arbitrario remotamente cuando se combina con un dispositivo de deserialización al escuchar el tráfico de red no confiable para datos de registro. Esto afecta a Log4j versiones desde 1.2 hasta 1.2.17. A flaw was discovered in Log4j, where a vulnerable SocketServer class may lead to the deserialization of untrusted data. • https://github.com/shadow-horse/CVE-2019-17571 https://github.com/Al1ex/CVE-2019-17571 http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00022.html https://lists.apache.org/thread.html/277b4b5c2b0e06a825ccec565fa65bd671f35a4d58e3e2ec5d0618e1%40%3Cdev.tika.apache.org%3E https://lists.apache.org/thread.html/44491fb9cc19acc901f7cff34acb7376619f15638439416e3e14761c%40%3Cdev.tika.apache.org%3E https://lists.apache.org/thread.html/479471e6debd608c837b9815b76eab24676657d4444fcfd5ef96d6e6%40%3Cdev.tika.apache.org%3E https://lists.apache& • CWE-502: Deserialization of Untrusted Data •
CVSS: 5.3EPSS: 0%CPEs: 18EXPL: 0CVE-2019-1551 – rsaz_512_sqr overflow bug on x86_64
https://notcve.org/view.php?id=CVE-2019-1551
There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00030.html http://packetstormsecurity.com/files/155754/Slackware-Security-Advisory-openssl-Updates.html https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=419102400a2811582a7a3d4a4e317d72e5ce0a8f https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=f1c5eea8a817075d31e43f5876993c6710238c98 https://lists.debian.org/debian-lts-announce/2022/03/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/messag • CWE-190: Integer Overflow or Wraparound •
CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •
