-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Reference: CERT-EU Security Advisory 2012-0014 Title: Multiple vulnerabilities in JBoss Operations Network [1] Version history: 03.02.2012 Initial publication Summary ======= Red Hat has released fixes to JBoss Operations Network (JBoss ON) [2], a middleware management solution that provides a single point of control to deploy, manage, and monitor JBoss Enterprise Middleware, applications, and services. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section [3-8]. 734662 - CVE-2011-3206 JON: Multiple XSS flaws 750521 - CVE-2011-4858 tomcat: hash table collisions CPU usage DoS (oCERT-2011-003) 760024 - CVE-2011-4573 JON: Incorrect delete permissions check 781964 - CVE-2012-0052 JON: Unapproved agents can connect using the name of an existing approved agent 783008 - CVE-2012-0062 JON: Unapproved agents can hijack an approved agent's endpoint by using a null security token Original Details ================ JBoss ON did not properly verify security tokens, allowing an unapproved agent to connect as an approved agent. A remote attacker could use this flaw to spoof the identity of an approved agent, allowing them to hijack the approved agent's session and steal its security token. As a result, the attacker could retrieve sensitive data about the server the hijacked agent was running on, including JMX credentials. (CVE-2012-0052) JBoss ON sometimes allowed agent registration to succeed when the registration request did not include a security token. This is a feature designed to add convenience. A remote attacker could use this flaw to spoof the identity of an approved agent and pass a null security token, allowing them to hijack the approved agent's session, and steal its security token. As a result, the attacker could retrieve sensitive data about the server the hijacked agent was running on, including JMX credentials. (CVE-2012-0062) It was found that the Java hashCode() method implementation was susceptible to predictable hash collisions. A remote attacker could use this flaw to cause JBoss Web to use an excessive amount of CPU time by sending an HTTP request with a large number of parameters whose names map to the same hash value. This update introduces a limit on the number of parameters and headers processed per request to mitigate this issue. The default limit is 512 for parameters and 128 for headers. These defaults can be changed by setting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in "server/$PROFILE/deploy/properties-service.xml". (CVE-2011-4858) Multiple cross-site scripting (XSS) flaws were found in the JBoss ON administration interface. If a remote attacker could trick a user, who was logged into the JBoss ON administration interface, into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's JBoss ON session. (CVE-2011-3206) JBoss ON did not verify that a user had the proper modify resource permissions when they attempted to delete a plug-in configuration update from the group connection properties history. This could allow such a user to delete a plug-in configuration update from the audit trail. Note that a user without modify resource permissions cannot use this flaw to make configuration changes. (CVE-2011-4573) What can you do? ================ This update is available via the Red Hat Network [1]. All users of JBoss Operations Network 2.4.1 as provided from the Red Hat Customer Portal are advised to upgrade to JBoss Operations Network 2.4.2.
