info:
  name: LDAP Injection In OpenAM
  author: melbadry9,xelkomy
  severity: high
  description: OpenAM contains an LDAP injection vulnerability. When a user tries to reset his password, they are asked to enter username, and then the backend validates whether the user exists or not through an LDAP query. If the user exists, the password reset token is sent to the user's email. Enumeration can allow for full password retrieval.
  impact: |
    Allows an attacker to execute arbitrary LDAP queries and potentially gain unauthorized access to sensitive information or perform unauthorized actions
  remediation: Upgrade to OpenAM commercial version 13.5.1 or later.
