  • with file uploads through ASM, it always needs to define a explicit "file upload parameter" for a upload link. If not done, ASM will detect lot of false positives when it parse the attachement (e.g. images, pdf or docs).

     

    Plesae go through the below article and create necessary upload parameter.

      in V15 , even if you choose Data Type to be File upload , the attack signture tab will still exist. Shall we have to disable attack check from file upload parameter?

  • which attack signature that blocked you and if you are sure that it is normal application behaviour you can allow it under matched parameter.

     

    check this article to Configuring attack signatures for a parameter
