IPW Systems Metazo had an unauthenticated SSTI that was leading to RCE in it. An unprotected route would happily just evaluate smarty template language leading to unauthenticated RCE directly.

This blog post tells the weird story on how I unexpectedly attended the training for Advanced Windows Exploitation (OSEE) in London

This blog post will give an insight into the world of becoming an Offensive Security Exploit Developer and concluding the journey to OSCE³

Kardex MLOG has an insecure path join, which allows to include files locally or from a remote smb server. In combination with the template rendering of .t4 files a SSTI is possible and allows for RCE. This blog post will describe how I found this vulnerability and how to leverage it to gain a reverse shell.
