Oracle Weblogic PreAuth Remote Command Execution
Posted on 12 June 2023
Oracle Weblogic versions 12.2.1.3.0, 12.2.1.4.0 and 14.1.1.0.0 prior to the Jan 2023 security update are vulnerable to an unauthenticated remote code execution vulnerability due to a post deserialization vulnerability. This Metasploit module exploits this vulnerability to trigger the JNDI connection to a LDAP server you control. The LDAP server will then respond with a remote reference response that points to a HTTP server that you control, where the malicious Java class file will be hosted. Oracle Weblogic will then make an HTTP request to retrieve the malicious Java class file, at which point our HTTP server will serve up the malicious class file and Oracle Weblogic will instantiate an instance of that class, granting us remote code execution as the oracle user.
