High severity with no evidence of exploitation so far.

What to do

  1. Check which version of R2R you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A vulnerability was determined in SciPhi-AI R2R up to 3.6.6. This affects an unknown part of the component JWT Secret Handler. This manipulation of the argument DEFAULT_BCRYPT_SECRET_KEY/DEFAULT_NACL_SECRET_KEY causes hard-coded credentials. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

The underlying weakness: Use of Hard-coded Password

The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound authentication to external components.

How developers prevent this class of flaw

  • For outbound authentication: store passwords outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible.
  • For inbound authentication: Rather than hard-code a default username and password for first time logins, utilize a first login mode that requires the user to enter a unique strong password.
  • Perform access control checks and limit which entities can access the feature that requires the hard-coded password. For example, a feature might only be enabled through the system console instead of through a network connection.
