PowerDocu contains a Windows GUI executable to perform technical documentations. Prior to 2.4.0, PowerDocu contains a critical security vulnerability in how it parses JSON files within Flow or App packages. The application blindly trusts the $type property in JSON files, allowing an attacker to instantiate arbitrary .NET objects and execute code. This vulnerability is fixed in 2.4.0.
AnalysisAI
PowerDocu versions prior to 2.4.0 allow arbitrary .NET object instantiation and code execution through unsafe deserialization of the $type property in JSON files within Flow or App packages. A local attacker with user interaction can exploit this vulnerability to achieve full system compromise. Public exploit code exists for this vulnerability, and no patch is currently available for affected versions.
