This proof of concept abuses an SQL injection vulnerability in MOVEit to obtain a sysadmin API access token and then use that access to abuse a deserialization call to obtain remote code execution. This proof of concept needs to reach out to an Identity Provider endpoint which hosts proper RS256 certificates used to forge arbitrary user tokens – by default this POC uses horizon3ai’s IDP endpoint hosted in AWS. By default, the exploit will write a file to C:WindowsTempmessage.txt. Alternative payloads can be generated by using the project.
