  name: WAPPLES Web Application Firewall <=6.0 - Hardcoded Credentials
  author: For3stCo1d

  description: |
    WAPPLES Web Application Firewall through 6.0 contains a hardcoded credentials vulnerability. It contains a hardcoded system account accessible via db/wp.no1, as configured in the /opt/penta/wapples/script/wcc_auto_scaling.py file. An attacker can use this account to access system configuration and confidential information, such as SSL keys, via an HTTPS request to the /webapi/ URI on port 443 or 5001.
  impact: |
    An attacker can exploit this vulnerability to gain unauthorized access to the WAPPLES Web Application Firewall.
  remediation: |
    Upgrade to a version of WAPPLES Web Application Firewall that does not contain hardcoded credentials or apply the vendor-provided patch to fix the vulnerability.
