Official description
A flaw was found in AWX. The container group pod_spec_override field uses an incomplete blocklist that only restricts automountServiceAccountToken, allowing injection of initContainers, serviceAccountName overrides, and projected service account token volumes. An AAP platform administrator can exploit this to escalate privileges to OpenShift namespace-level access and exfiltrate namespace secrets.

The underlying weakness: Incomplete List of Disallowed Inputs
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.
How developers prevent this class of flaw
- Do not rely exclusively on detecting disallowed inputs. There are too many variants to encode a character, especially when different environments are used, so there is a high likelihood of missing some variants. Only use detection of disallowed inputs as a mechanism for detecting suspicious activity. Ensure that you are using other protection mechanisms that only identify good input - such as lists of allowed inputs - and ensure that you are properly encoding your outputs.
