Signature Detail

HTTP: Encoded Shellcode in Adobe PDF JavaScript

This signature detects a unicoded Shell code in PDF files sent via HTTP. The presence of a unicoded shell code value in a PDF indicates that something malicious is occurring. It is recommended that you check the PDF contents before running any script included in this document. Some known cases resulted in remote arbitrary code execution. A common malware tactic is to set a OpenAction parameter that runs the malicious JavaScript when the document is opened.

An attacker can exploit this issue to execute arbitrary code with the privileges of the user running the application or crash the application, denying service to legitimate users.
