Solution
No solution given by the vendor.
Workaround
To mitigate this issue, enforce conservative HTTP request-body limits on the `/ipa/session/json` endpoint to reject oversized payloads before they reach the vulnerable IPA parameter conversion. Additionally, if operationally feasible, restrict self-managed token creation to trusted users and implement monitoring or rate-limiting for repeated large authenticated requests. Changes to HTTP server configurations or FreeIPA permissions may require service restarts or reloads to take effect.

| Type | Values Removed | Values Added |
|---|---|---|
| Description | A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password (OTP) key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a denial of service, degrading the availability of the IPA service. | |
