Error description

  • False positive rule results can be experienced due to the rule
    "QNI: File Extension/Content Type Verification" from QNI
    Content Pack v1.5.1
    Files with names containing more than one dot(.) are handled
    incorrectly by the rule.
    For example:
    Have a flow with filename "jquery-1.8.3.js" and content type =
    "application/javascript".
    The rule uses an AQL filter test:
    "when the flow matches
        strpos("file name",'.') >= 0 and
        not REFERENCESETCONTAINS('QNI : File Extension / Content
    Type Verification Exclusions', LOWER(SUBSTRING("file
    name",STRPOS("file name",'.'),STRLEN("file name")))) and
        not
    REFERENCEMAPSETCONTAINS('QNI-Extension-ContentType-Pairs',LOWER(
    SUBSTRING("file name",STRPOS("file name",'.'),STRLEN("file
    name"))),"content type")
    AQL filter query"
    The STRPOS("file name",'.') returns the first dot position,
    which captures .8.3.js instead of .js in above example and so
    the combination cannot be found in reference map.
