Michael Stepankin, Researcher at PortSwigger
“I discovered all servers that responded to the “/well-known/openid-configuration” URI and took a brief look at their configuration. As my intention was to find truly impactful vulnerabilities rather than just “something,” I decided to focus on the systems that are either open source or available to download and decompile. ForgeRock OpenAm was one such system that I found in the bug bounty scope. It appeared to me as a monstrous Java Enterprise application with a huge attack surface, so I decided to take a deeper look into it.”
The vulnerability allows hackers to remotely execute code on an affected system through a mechanism for remote code execution. The main goal of malicious actors is to compromise multiple hosts and deploy additional malware and tools. According to the company’s advisory guide, this flaw does not affect AM 7 and above nor ForgeRock Identity Cloud.
