jackson-databind before 2.13.0 allows a Java StackOverflow exception and denial of service via a large depth of nested objects. jackson-databind versiones anteriores a 2.13.0, permite una excepción Java StackOverflow y una denegación de servicio por medio de una gran profundidad de objetos anidados A flaw was found in the Jackson Databind package. This cause of the issue is due to a Java StackOverflow exception and a denial of service via a significant depth of nested objects. • https://github.com/FasterXML/jackson-databind/issues/2816 https://lists.debian.org/debian-lts-announce/2022/05/msg00001.html https://lists.debian.org/debian-lts-announce/2022/11/msg00035.html https://security.netapp.com/advisory/ntap-20220506-0004 https://www.debian.org/security/2022/dsa-5283 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2020-36518 https://bugzilla.redhat.com/ • CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •

dom4j before 2.0.3 and 2.1.x before 2.1.3 allows external DTDs and External Entities by default, which might enable XXE attacks. However, there is popular external documentation from OWASP showing how to enable the safe, non-default behavior in any application that uses dom4j. dom4j versiones anteriores a 2.0.3 y versiones 2.1.x anteriores a 2.1.3, permite DTDs y External Entities por defecto, lo que podría permitir ataques de tipo XXE. Sin embargo, existe una documentación externa popular de OWASP que muestra cómo habilitar el comportamiento seguro no predeterminado en cualquier aplicación que use dom4j. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00061.html https://bugzilla.redhat.com/show_bug.cgi?id=1694235 https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html https://github.com/dom4j/dom4j/commit/a8228522a99a02146106672a34c104adbda5c658 https://github.com/dom4j/dom4j/commits/version-2.0.3 https://github.com/dom4j/dom4j/issues/87 https://github.com/dom4j/dom4j/releases/tag/version-2.1.3 https://lists.apache.org/thread.html/r51f3f9801058 • CWE-611: Improper Restriction of XML External Entity Reference •
CVSS: 9.8EPSS: 97%CPEs: 38EXPL: 18CVE-2020-1938 – Apache Tomcat Improper Privilege Management Vulnerability
https://notcve.org/view.php?id=CVE-2020-1938
When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. If such connections are available to an attacker, they can be exploited in ways that may be surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected (and recommended in the security guide) that this Connector would be disabled if not required. • https://www.exploit-db.com/exploits/49039 https://www.exploit-db.com/exploits/48143 https://github.com/sgdream/CVE-2020-1938 https://github.com/xindongzhuaizhuai/CVE-2020-1938 https://github.com/laolisafe/CVE-2020-1938 https://github.com/sv3nbeast/CVE-2020-1938-Tomact-file_include-file_read https://github.com/fairyming/CVE-2020-1938 https://github.com/dacade/CVE-2020-1938 https://github.com/Hancheng-Lei/Hacking-Vulnerability-CVE-2020-1938-Ghostcat https://github.com/w4fz5uck5& • CWE-285: Improper Authorization •
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') •
