- CWE-770 - Allocation of Resources Without Limits or Throttling
Summary
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition.

This can be achieved by adding `LimitRequestBody` directive within the Apache configuration for IPA. For example, to limit the request body to 1MB, add `LimitRequestBody 1048576` to the relevant `\u003cLocation \"/ipa/i18n_messages\"\u003e` block or a broader `/ipa/*` location. A restart of the Apache HTTP Server (`httpd`) service is required for the changes to take effect, which may temporarily impact FreeIPA service availability. If a reverse proxy or load balancer is used, ensure it also enforces an equivalent body-size limit."
