CVSS: 5.8EPSS: 0%CPEs: 60EXPL: 0CVE-2020-1935 – tomcat: Mishandling of Transfer-Encoding header allows for HTTP request smuggling
https://notcve.org/view.php?id=CVE-2020-1935
In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led 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. En Apache Tomcat versiones 9.0.0.M1 hasta 9.0.30, versiones 8.5.0 hasta 8.5.50 y versiones 7.0.0 hasta 7.0.99, el código de análisis del encabezado HTTP utilizó un enfoque para el análisis de fin de línea que permitió a algunos encabezados HTTP no válidos ser analizados como válidos. Esto conllevó 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 en una manera particular. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00025.html https://lists.apache.org/thread.html/r127f76181aceffea2bd4711b03c595d0f115f63e020348fe925a916c%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/r441c1f30a252bf14b07396286f6abd8089ce4240e91323211f1a2d75%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/r660cd379afe346f10d72c0eaa8459ccc95d83aff181671b7e9076919%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/r7bc994c965a34876bd94d5ff15b4e1e30b6220a15eb9b47c81915b78%40%3Ccommits.tomee.apache.org%3E • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response 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: 5.3EPSS: 0%CPEs: 52EXPL: 1CVE-2020-5397 – CSRF Attack via CORS Preflight Requests with Spring MVC or Spring WebFlux
https://notcve.org/view.php?id=CVE-2020-5397
Spring Framework, versions 5.2.x prior to 5.2.3 are vulnerable to CSRF attacks through CORS preflight requests that target Spring MVC (spring-webmvc module) or Spring WebFlux (spring-webflux module) endpoints. Only non-authenticated endpoints are vulnerable because preflight requests should not include credentials and therefore requests should fail authentication. However a notable exception to this are Chrome based browsers when using client certificates for authentication since Chrome sends TLS client certificates in CORS preflight requests in violation of spec requirements. No HTTP body can be sent or received as a result of this attack. Spring Framework, versiones 5.2.x anteriores a 5.2.3 son vulnerables a los ataques de tipo CSRF por medio de peticiones de verificación previa CORS que van dirigidas a los endpoints Spring MVC (módulo spring-webmvc) o Spring WebFlux (módulo spring-webflux). • https://pivotal.io/security/cve-2020-5397 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2020.html https://www.oracle.com/security-alerts/cpujul2020.html https://www.oracle.com/security-alerts/cpujul2022.html https://www.oracle.com/security-alerts/cpuoct2020.html https://www.oracle.com/security-alerts/cpuoct2021.html • CWE-352: Cross-Site Request Forgery (CSRF) •

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 •

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 •
