The following Red Hat products are impacted:
- Enterprise Application Platform 5.2
- Red Hat JBoss BRMS 5.3.1
- Red Hat JBoss SOA Platform 5.3.1
- Red Hat Developer Studio 12.9
An application that uses certain features in RichFaces could permit an unauthenticated user to send a specially-crafted object that contains a tainted expression, the evaluation of which triggers deserialization after clearing any whitelist protections. This can result in execution of arbitrary java code or possibly system code.
Red Hat Product Engineering is actively developing patches all affected Red Hat products. Additional details on the vulnerability and all advisories related to this issue can review CVE-2018-14667 . Customers running affected versions of Red Hat products are strongly recommended to update as soon as errata are available, and to apply the updates immediately.
To mitigate this vulnerability, customers are advised to disable Expression Language evaluation in RichFaces; or, if this is not feasible, to add sanitization of any Expression Language received from untrusted sources. Expression Language whitelisting could be added after ResourceBuilderImpl class in its getResourceDataForKey method invokes LookAheadObjectInputStream (which deserializes data based on whitelisted classes).
