The implementations of PKCS#1 v1.5 key transport mechanism for XMLEncryption in JBossWS and Apache WSS4J before 1.6.5 is susceptible to a Bleichenbacher attack.

A flaw was discovered in jackson-databind in versions before 2.9.10, 2.8.11.5 and 2.6.7.3, where it would permit polymorphic deserialization of a malicious object using commons-configuration 1 and 2 JNDI classes. An attacker could use this flaw to execute arbitrary code.

HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header.

HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold."

Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869.

A flaw was found in the JBoss EAP Vault system in all versions before 7.2.6.GA. Confidential information of the system property's security attribute value is revealed in the JBoss EAP log file when executing a JBoss CLI 'reload' command. This flaw can lead to the exposure of confidential information.

EJB method in Red Hat JBoss BRMS 5; Red Hat JBoss Enterprise Application Platform 5; Red Hat JBoss Operations Network 3.1; Red Hat JBoss Portal 4 and 5; Red Hat JBoss SOA Platform 4.2, 4.3, and 5; in Red Hat JBoss Enterprise Web Server 1 ignores roles specified using the @RunAs annotation.

A vulnerability was found in the Undertow HTTP server in versions before 2.0.28.SP1 when listening on HTTPS. An attacker can target the HTTPS port to carry out a Denial Of Service (DOS) to make the service unavailable on SSL.

It was found that keycloak before version 8.0.0 exposes internal adapter endpoints in org.keycloak.constants.AdapterConstants, which can be invoked via a specially-crafted URL. This vulnerability could allow an attacker to access unauthorized information.

A flaw was found in Wildfly Security Manager, running under JDK 11 or 8, that authorized requests for any requester. This flaw could be used by a malicious app deployed on the app server to access unauthorized information and possibly conduct further attacks. Versions shipped with Red Hat Jboss EAP 7 and Red Hat SSO 7 are vulnerable to this issue.
