CVSS: 8.8EPSS: 0%CPEs: 7EXPL: 0CVE-2020-1714 – keycloak: Lack of checks in ObjectInputStream leading to Remote Code Execution
https://notcve.org/view.php?id=CVE-2020-1714
A flaw was found in Keycloak before version 11.0.0, where the code base contains usages of ObjectInputStream without type checks. This flaw allows an attacker to inject arbitrarily serialized Java Objects, which would then get deserialized in a privileged context and potentially lead to remote code execution. Se detectó un fallo en Keycloak versiones anteriores a 11.0.0, donde la base de código contiene usos de la función ObjectInputStream sin ningún tipo de comprobaciones. Este fallo permite a un atacante inyectar Objetos Java serializados arbitrariamente, que luego se deserializarán en un contexto privilegiado y conlleva potencialmente a una ejecución de código remota.

CVSS: 9.1EPSS: 0%CPEs: 8EXPL: 0CVE-2019-14887 – wildfly: The 'enabled-protocols' value in legacy security is not respected if OpenSSL security provider is in use
https://notcve.org/view.php?id=CVE-2019-14887
A flaw was found when an OpenSSL security provider is used with Wildfly, the 'enabled-protocols' value in the Wildfly configuration isn't honored. An attacker could target the traffic sent from Wildfly and downgrade the connection to a weaker version of TLS, potentially breaking the encryption. This could lead to a leak of the data being passed over the network. Wildfly version 7.2.0.GA, 7.2.3.GA and 7.2.5.CR2 are believed to be vulnerable. Se detectó un fallo cuando un proveedor de seguridad OpenSSL es usado con Wildfly, el valor de "enabled-protocols" en la configuración de Wildfly no es respetado. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14887 https://issues.redhat.com/browse/JBEAP-17965 https://security.netapp.com/advisory/ntap-20200327-0007 https://access.redhat.com/security/cve/CVE-2019-14887 https://bugzilla.redhat.com/show_bug.cgi?id=1772008 • CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') •
