Описание
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.
Меры по смягчению последствий
To mitigate this issue, configure Apache to enforce a request-body limit for the /ipa/i18n_messages endpoint. 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 <Location "/ipa/i18n_messages"> 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.
