Recently, I had the privilege to write a detailed analysis of CVE-2023-34362, which is series of several vulnerabilities in the MOVEit file transfer application that lead to remote code execution. One of the several vulnerabilities involved an ISAPI module - specifically, the MoveITISAPI.dll ISAPI extension. One of the many vulnerabilities that comprised the MOVEit RCE was a header-injection issue, where the ISAPI application parsed headers differently than the .net application. This point is going to dig into how to analyze and reverse engineer an ISAPI-based service! This wasn’t the first time in the recent past I’d had to work on something written as an ISAPI module, and each time I feel like I have to start over and remember how it’s supposed to work. This time, I thought I’d combine my hastily-scrawled notes with some Googling, and try to write something that I (and others) can use in the future. As such, this will be a quick intro to ISAPI applications from the angle that matters to me - how to reverse engineer and debug them! I want to preface this with: I’m not a Windows developer, and I’ve never run an IIS server on purpose. That means that I am approaching this with brute-force ignorance! I don’t have a lot of background context nor do I know the correct terminology for a lot of this stuff. Instead, I’m going to treat these are typical DLLs from typical applications, and approach them as such.
