SERVER-WEBAPP -- Snort has detected traffic exploiting vulnerabilities in web based applications on servers.
SERVER-WEBAPP Apache OFBiz XMLRPC unsafe deserialization attempt
This rule looks for Java RMI classes in a serialized request to the Apache OFBiz SOAP service endpoint. These classes can be used to abuse the deserialization offered by the SOAP endpoint, and can lead to full compromise of the underlying operating system hosting the Apache OFBiz website.
This rule alerts on an attempt to exploit an unsafe deserialization vulnerability in Apache OFBiz.

Insecure Deserialization
Insecure Deserialization relates to web application security. Applications turn an object into data through serialization; the reverse of that process, deserialization, can be vulnerable to attacks when the application trusts the data that is being deserialized. Serialized data is machine readable and not encrypted; serialized user-supplied data should not be trusted. Deserialization attacks can lead to remote code execution.
