Intrusion PreventionOracle.WebLogic.Server.LinkRef.JNDI.Injection
Description
This indicates an attack attempt to exploit a JNDI Injection Vulnerability in Oracle WebLogic Server.
This vulnerability is due to improper handling of user input when using the server naming service to bind a LinkRef object. A remote, unauthenticated attacker can exploit this vulnerability by sending a crafted request to a vulnerable server. Successful exploitation results in the target server performing a JNDI lookup to an attacker controlled server, and in the worst case execution of arbitrary code under the security context of the affected server.
