OpenAM: Unauthenticated Remote Code Execution via Class.forName in AuthXMLUtils.createCustomCallback
Quick fix
GHSA-wg5r-wc3x-39vc — org.openidentityplatform.openam:openam-core: upgrade to the fixed version with the command below.
# pom.xml: bump <version>16.1.2</version> for org.openidentityplatform.openam:openam-coreDetails
## Summary A pre-authentication remote code execution vulnerability affects OpenAM. The remote authentication endpoint (`/authservice`, PLL) accepts an XML element that names an arbitrary Java class, which the server then loads and instantiates without validation. On a default configuration this is reachable **without authentication** and allows an attacker to run code on the server.
## Impact Unauthenticated remote code execution / full server compromise on any OpenAM instance with default settings.
## Affected All releases up to and including 16.1.1 (the defect predates the Open Identity Platform fork).
## Remediation Upgrade to `16.1.2`.
## Interim mitigation - Require the remote-auth security token by enabling `sunRemoteAuthSecurityEnabled` (rejects unauthenticated `/authservice` calls). - Restrict or block external network access to `/authservice` until patched.
