Remediation status
No patch has shipped for CVE-2024-29059 yet — track the microsoft .net framework advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
