The remote Red Hat host is missing one or more security updates.
Updated jbossas packages that fix one security issue are now available
for JBoss Enterprise Application Platform 4.3.0 CP10 for Red Hat
Enterprise Linux 4 and 5.
The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.
JBoss Web is the web container, based on Apache Tomcat, in JBoss
Enterprise Application Platform. It provides a single deployment
platform for the JavaServer Pages (JSP) and Java Servlet technologies.
It was found that when an application used FORM authentication, along
with another component that calls request.setUserPrincipal() before
the call to FormAuthenticator#authenticate() (such as the
Single-Sign-On valve), it was possible to bypass the security
constraint checks in the FORM authenticator by appending
'/j_security_check' to the end of a URL. A remote attacker with an
authenticated session on an affected application could use this flaw
to circumvent authorization controls, and thereby access resources not
permitted by the roles associated with their authenticated session.
Warning: Before applying this update, back up your JBoss Enterprise
Application Platform's 'server/[PROFILE]/deploy/' directory, along
with all other customized configuration files.
Users of JBoss Enterprise Application Platform 4.3.0 CP10 on Red Hat
Enterprise Linux 4 and 5 should upgrade to these updated packages,
which correct this issue. The JBoss server process must be restarted
for this update to take effect.
