Insecure dependency in eval while running with -T switch on perl and ubuntu 16.04

I have a small issue with the following line of text when loading the apache website of foswiki on Ubuntu 16.04.

Error:

Foswiki detected an internal error – please check your Foswiki logs and webserver logs for more information.

Insecure dependency in eval while running with -T switch

Log from error.log:

Insecure dependency in eval while running with -T switch at /var/www/Foswiki-1.1.9/lib/Foswiki.pm line 3153.

**Background: **

  • Originally the VM was on ubuntu 12.04 and running foswiki 1.1.9.
  • then I ran the upgrade on ubuntu and made it to 14.04 and was able to make the apache webservice work for foswiki.
  • then I upgraded it to ubuntu 16.04 and seeing the error above.
  • on ubuntu 12.04: perl version was 5.14
  • on ubuntu 16.04: perl version is 5.22

Note: I have very limited knowledge in programming language and I need to upgrade this VM all the way up to ubuntu 20.04 LTS or 22.04 what ever I can.

    Found the workaround to this problem:

    1. all the scripts in this location: varwwwFoswiki-1.1.9
    2. removed the -wT from the scripts and started working fine.

    The program was run using perl -T or as a setuid/setgid script, which enables taint mode. Taint mode prevents user inputs from being used in certain operations for security purposes. This is particularly appropriate for a web script.

    Changes to the program or module will be needed to resolve the issue. Please consult their authors.
