[Pkg-nagios-devel] Bug#913142: monitoring-plugins-basic: check_http sending extra CRLF after POST data

Wed Nov 7 13:26:15 GMT 2018

Package: monitoring-plugins-basic
Version: 2.2-3
Severity: normal

Dear Maintainer,

   * What led up to the situation ? Using check_http with POST data
   * What exactly did you do (or not do) that was effective (or ineffective) ? check_http is used with POST data to check a web application is answerng properly
   * What was the outcome of this action ? Extra CRLF triggering alarm in WAF because not complying to RFC
   * What outcome did you expect instead ? Packet not blocked by WAF

This is a known bug which could lead to security issues (disabled WAF checks to allow requests). cf : https://github.com/nagios-plugins/nagios-plugins/issues/266
