The register method in the UsersModelRegistration class in controllers/user.php in the Users component in Joomla! before 3.6.4 allows remote attackers to gain privileges by leveraging incorrect use of unfiltered data when registering on a site. This registration works even when registration has been disabled. This module exploits this vulnerability to add an administrator user to the Joomla database. Notice that this account could need registration confirmation (activation).
An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java object to the Jenkins CLI, making Jenkins connect to an attacker-controlled LDAP server, which in turn can send a serialized payload leading to code execution, bypassing existing protection mechanisms. This can be exploited by malicious local attackers to gain SYSTEM privileges on Windows targets.
