FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to org.apache.commons.dbcp2.datasources.SharedPoolDataSource. FasterXML jackson-databind versiones 2.x anteriores a 2.9.10.8, maneja inapropiadamente la interacción entre los gadgets de serialización y la escritura, relacionada con org.apache.commons.dbcp2.datasources.SharedPoolDataSource A flaw was found in jackson-databind. FasterXML mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://cowtowncoder.medium.com/on-jackson-cves-dont-panic-here-is-what-you-need-to-know-54cd0d6e8062 https://github.com/FasterXML/jackson-databind/issues/2986 https://lists.debian.org/debian-lts-announce/2021/04/msg00025.html https://security.netapp.com/advisory/ntap-20210122-0005 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuApr2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022&# • CWE-96: Improper Neutralization of Directives in Statically Saved Code ('Static Code Injection') CWE-502: Deserialization of Untrusted Data •
CVSS: 7.5EPSS: 0%CPEs: 55EXPL: 1CVE-2020-17527 – Apache Tomcat: Request header mix-up between HTTP/2 streams
https://notcve.org/view.php?id=CVE-2020-17527
While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. Al investigar el error 64830, se detectó que Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M9, versiones 9.0.0-M1 hasta 9.0.39 y versiones 8.5.0 hasta 8.5.59, podría reutilizar un valor de encabezado de petición HTTP de la transmisión anterior recibida en una conexión HTTP/2 para la petición asociada con la transmisión posterior. Si bien esto probablemente conllevaría a un error y al cierre de la conexión HTTP/2, es posible que la información podría filtrarse entre peticiones • https://github.com/forse01/CVE-2020-17527-Tomcat http://www.openwall.com/lists/oss-security/2020/12/03/3 https://lists.apache.org/thread.html/r26a2a66339087fc37db3caf201e446d3e83b5cce314371e235ff1784%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r2d6e05c5ff96f8068a59dfdb3800e9ee8d4e36ce1971783c6e5f9b20%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r5a285242737ddef4d338236328aaaf3237183e1465a5efafd16b99ed%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/r8a227ac6a755a6406c1cc47dd48800e973d4cf13fe7f • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
