EXPLOIT

An issue was discovered in Electronic Arts Origin before 10.5.39. Due to improper sanitization of the origin:// and origin2:// URI schemes, it is possible to inject additional arguments into the Origin process and ultimately leverage code execution by loading a backdoored Qt plugin remotely via the platformpluginpath argument supplied with a Windows network share.

• → Monitor process creation for Origin.exe spawned with Qt argument injection flags such as -platformpluginpath, -reverse, -Origin_MultipleInstances, /noUpdate, or /StartClientMinimized in the command line. ↗
• → Alert on Origin.exe loading DLLs from UNC/Windows network share paths (\\server\share\...) via the -platformpluginpath argument, indicating remote plugin loading. ↗
• → Inspect iframe or HTML content for origin:// or origin2:// URI schemes with appended argument injection patterns (e.g., embedded quotes and Qt/Origin flags). ↗
• → Monitor for DLL loads by Origin.exe from the imageformats subdirectory of a UNC network path, which is the plugin directory used to deliver the backdoored Qt plugin payload. ↗

• · The backdoored Qt plugin DLL must contain a valid .qtmetad section to be loaded by Origin; a generic DLL without this section will be rejected by the Qt plugin loader. ↗
