infiniflow/ragflow: Deserialization of Untrusted Data
CVE-2024-12433 is a critical-severity deserialization of untrusted data vulnerability in infiniflow/ragflow from InfiniFlow, with a CVSS 3.0 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 0.14.0 as the first without the flaw, so updating infiniflow/ragflow to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.69% chance of exploitation within 30 days, higher than 77% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update infiniflow/ragflow to 0.14.0 or a later version.
- Update Ragflow to 0.14.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A vulnerability in infiniflow/ragflow versions v0.12.0 allows for remote code execution. The RPC server in RagFlow uses a hard-coded AuthKey 'authkey=b'infiniflow-token4kevinhu'' which can be easily fetched by attackers to join the group communication without restrictions. Additionally, the server processes incoming data using pickle deserialization via `pickle.loads()` on `connection.recv()`, making it vulnerable to remote code execution. This issue is fixed in version 0.14.0.

The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
