The best solution will be to change the container image to have an updated iptables version, but in case you can't do that, follow the next steps.

Environment

  • Red Hat OpenShift Container Platform 4.6+

Issue

Executing iptables command in an application container fails with the following error.

 

[root@pod]# iptables -L iptables v1.8.4 (legacy): can't initialize iptables table `filter': Permission denied Perhaps iptables or your kernel needs to be upgraded.

DotDotPwn - The Directory Traversal Fuzzer.
It's a very flexible intelligent fuzzer to discover traversal directory vulnerabilities in software such as Web/FTP/TFTP servers, Web platforms such as CMSs, ERPs, Blogs, etc. Also, it has a protocol-independent module to send the desired payload to the host and port specified. On the other hand, it also could be used in a scripting way using the STDOUT module. It's written in perl programming language and can be run either under *NIX or Windows platforms.
