Short explanation
The Wildfly IIOP listener may permit deserialization of input streams before authentication is performed. This can lead to exploitation if the target EJB allows untyped method parameters and gadget chains are present in the classpath.
An unauthorized attacker can compromise sensitive data or affect system integrity depending on the EJB parameter configuration and available gadget chains in the running classpath.
What should be done?
- Follow Red Hat security advisories
- Configure EJB method parameters
- Restrict access to the IIOP port
Chain of evidence and sources
Wildfly IIOP dinleyicisi, kimlik doğrulaması yapılmadan önce girdi akışlarının seri durumdan çıkarılmasına izin verebilir.
Etkilenen ürünler arasında Red Hat JBoss Enterprise Application Platform 7 ve 8 bulunmaktadır.
Show the technical text from the sources
Wildfly's IIOP listener may permit deserialization of input streams before authentication is performed. An attacker who can gain access to the IIOP port may be able to construct and send malicious objects and achieve deserialization, if the target EJB allows untyped method parameters, and depending on the potential gadget chains available in the running classpath.
