Command Injection in DIRAC Interware

Publication date: 2026-09-15

Last updated on: 2026-09-15

Assigner: GitHub, Inc.

Description
DIRAC is an interware, meaning a software framework for distributed computing. Prior to versions 8.0.79, 9.0.22, and 9.1.10, DataManagementSystem/Service/FileCatalogHandler.py checkDataset forwards an authenticated caller-controlled datasets value to DatasetManager.py __checkDataset, where datasetName is interpolated into an FC_MetaDatasets SQL query without parameterization. The injected query can control the returned MetaQuery value, which is passed to Python eval and permits command execution as the account running the DIRAC services. Successful exploitation can expose dirac.cfg, database passwords, stored proxies, and tokens, fully compromise the DIRAC system, and allow alteration of local log evidence. This issue is fixed in versions 8.0.79, 9.0.22, and 9.1.10.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-95 The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval").

Executive Summary

This vulnerability exists in DIRAC versions before 8.0.79, 9.0.22, and 9.1.10. It involves improper handling of a datasets parameter in the FileCatalogHandler.py component, which allows an authenticated attacker to inject malicious SQL queries. The injected query can manipulate the MetaQuery value returned, which is then passed to Python's eval function, enabling arbitrary command execution with the privileges of the DIRAC service account.

Detection Guidance

This vulnerability involves SQL injection leading to command execution via Python eval. Detection requires checking DIRAC versions prior to 8.0.79, 9.0.22, or 9.1.10. Inspect FileCatalogHandler.py for datasetName interpolation in SQL queries without parameterization.

Impact Analysis

Exploitation could expose sensitive configuration files like dirac.cfg, database passwords, stored proxies, and authentication tokens. It may lead to full compromise of the DIRAC system, allowing attackers to take control of the system. Additionally, attackers could alter local log evidence to hide their activities.

Compliance Impact

This vulnerability could lead to unauthorized access and exposure of sensitive data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. A successful exploit may result in data breaches, non-compliance penalties, and loss of trust in systems handling regulated data.

Mitigation Strategies

Upgrade DIRAC to versions 8.0.79, 9.0.22, or 9.1.10 or later immediately. Review and restrict access to DIRAC services to trusted users only. Monitor logs for unusual activity or unauthorized command execution attempts.
