A vulnerability in the init script component of Red Hat JBoss Enterprise Application Platform could allow a local attacker to escalate privileges on a targeted system.
The vulnerability exists because the affected software improperly performs a change owner command (chown) on the server.log file. An attacker who is a member of the jboss group could exploit this vulnerability to create symbolic links to critical system files and escalate privileges. A successful exploit could allow the attacker to escalate privileges and completely compromise the system.
Functional code that exploits this vulnerability is publicly available.
Red Hat has confirmed the vulnerability and released software updates.
To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement could reduce the likelihood of a successful exploit.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to access local systems.
Administrators are advised to allow only privileged users to access administration or management systems.
Administrators are advised to monitor critical systems.
Red Hat has released updated software for registered subscribers via the Red Hat Subscription Management (RHSM) service. Red Hat packages can be updated on Red Hat Enterprise Linux versions 5 and later using the yum tool.
