Description

Summary

A SQL injection vulnerability in the Oracle path of FilterEngine.create_sqla_query allows any authenticated Rucio user to execute arbitrary SQL against the backend database through the DID search endpoint (GET /dids/<scope>/dids/search). Attacker-controlled filter keys and values are interpolated directly into sqlalchemy.text via Python str.format, completely bypassing parameterization. This enables full database compromise including extraction of authentication tokens, password hashes, and all managed data identifiers. The vulnerability is affecting deployments using the default metadata plugin configuration json_meta with Oracle database backends.

Details

Will follow in two weeks (2025-05-19).

Impact

Vulnerability type: SQL Injection (CWE-89)

Who is impacted:

  • All Oracle-based Rucio deployments using the default metadata plugin configuration (json_meta).
  • Not affected are PostgreSQL/MySQL deployments using the default json_meta plugin (SQLAlchemy parameterizes the JSON path operations via bind parameters on non-Oracle dialects).

What an attacker can do:

  • Full database read access: Extract any table including identities (password hashes and salts), tokens (active authentication sessions), accounts (user enumeration), rse_settings (storage endpoint credentials), and rules (data management policies).
  • Password hash extraction: Combined with Rucio's use of single-iteration SHA-256 for password hashing (no KDF), extracted hashes can be cracked at GPU speed.
  • Authentication token theft: Active bearer tokens can be extracted and used for immediate session hijacking.
  • Data modification: Oracle PL/SQL enables INSERT/UPDATE/DELETE operations via DML within subqueries and PL/SQL blocks.
  • Potential remote code execution: Via Oracle's UTL_HTTP, DBMS_SCHEDULER, or Java stored procedures if the database user has elevated privileges.

Required attacker privileges: Any authenticated Rucio user. Authentication tokens can be obtained via any supported method (userpass, x509, OIDC, SAML, SSH, GSS). No special roles or administrative permissions are required. The GET /dids/<scope>/dids/search endpoint is available to all authenticated users.

Risk Scores
Base Score
9.9

The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
