Your script attempts to write tainted data to the filesystem. Running in taint mode protects you from doing this ...

This is not how taint mode works. You can write tainted data to the file system just fine. It is passing tainted data to the OS (via the file system, starting processes and the like) where taint mode kicks in.

A frequent path to taint failures is whenever environment variables like e.g. $ENV{HOME} or $ENV{TMP} are used by Perl modules. This may also differ between platforms. For example, my current Linux desktops don't even have $ENV{TMP} defined, whereas on Windows it is usually set.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
