-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: JBoss Operations Network 3.0.1 update Advisory ID: RHSA-2012:0406-01 Product: JBoss Enterprise Middleware Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0406.html Issue date: 2012-03-20 CVE Names: CVE-2011-4858 CVE-2012-0032 CVE-2012-0052 CVE-2012-0062 CVE-2012-1100 ===================================================================== 1. Summary: JBoss Operations Network 3.0.1, which fixes multiple security issues and several bugs, is now available from the Red Hat Customer Portal. 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. 2. Description: JBoss Operations Network (JBoss ON) is a middleware management solution that provides a single point of control to deploy, manage, and monitor JBoss Enterprise Middleware, applications, and services. This JBoss ON 3.0.1 release serves as a replacement for JBoss ON 3.0.0, and includes several bug fixes. Refer to the JBoss ON 3.0.1 Release Notes for information on the most significant of these changes. The Release Notes will be available shortly from https://docs.redhat.com/docs/en-US/index.html The following security issues are also fixed with this release: 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) A flaw was found in the way LDAP (Lightweight Directory Access Protocol) authentication was handled. If the LDAP bind account credentials became invalid, subsequent log in attempts with any password for user accounts created via LDAP were successful. A remote attacker could use this flaw to log into LDAP-based JBoss ON accounts without knowing the correct passwords. (CVE-2012-1100) 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) It was found that after installing the remote client (by extracting rhq-remoting-cli-[version].zip), its root directory had world read, write, and execute permissions. This allowed the attributes of the child directories and their files to be modified. A local attacker could use this flaw to steal the JBoss ON credentials of a user running the remote client, or trick them into running arbitrary code. The remote client is typically used by privileged JBoss ON users. (CVE-2012-0032) Red Hat would like to thank oCERT for reporting CVE-2011-4858. oCERT acknowledges Julian Wälde and Alexander Klink as the original reporters of CVE-2011-4858.
