Java JAR Attacks and Features
The Java runtime will load a JAR appended to a JPEG, so a file that passes image header checks is still executable byte code, and an applet runs in the sandbox of its codebase host. pdp chains the two: upload the polyglot to a target that accepts images, embed it from anywhere, and any internal visitor becomes a socket proxy onto the target's firewalled ports such as MSSQL.
