High [CVE-2026-73197] Unauthenticated DoS in `/ipa/migration/migration.py` via Unbounded Request Body Read
CVE-2026-73197Source published Source updated
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-770. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat does not currently list a fixing RHSA for this CVE. Affected…

- Mitigation guidance
- If the `/ipa/migration` endpoint is not required, it can be disabled by commenting out or removing the `Alias /ipa/migration` and its corresponding `<Directory>` block in the Apache configuration file (e.g., `/etc/httpd/conf.d/ipa.conf`). Alternatively, to limit the size of request bodies processed by the `/ipa/migration` endpoint, add the `LimitRequestBody` directive within the `<Directory "/usr/share/ipa/migration">` block in your Apache configuration, setting a conservative limit such as 1 MiB (1048576 bytes): ```apache <Directory "/usr/share/ipa/migration"> LimitRequestBody 1048576 # ... other directives ... </Directory> ``` After modifying the Apache configuration, the `httpd` service must be reloaded or restarted for the changes to take effect. This may temporarily interrupt service.
