Detailsinfo

A vulnerability, which was classified as problematic, has been found in DIRACGrid DIRAC up to 8.0.78/9.0.21/9.1.9. This issue affects some unknown processing of the file WorkloadManagementSystem/Utilities/PilotWrapper.py of the component Pilot Wrapper. The manipulation with an unknown input leads to a certificate validation vulnerability. Using CWE to declare the problem leads to CWE-295. The product does not validate, or incorrectly validates, a certificate. Impacted is integrity. The summary by CVE is:

DIRAC is an interware, meaning a software framework for distributed computing. Prior to versions 8.0.79, 9.0.22, and 9.1.10, WorkloadManagementSystem/Utilities/PilotWrapper.py pilotWrapperScript uses ssl._create_unverified_context to download the second-stage pilot.tar archive without TLS certificate verification and downloads the reference checksum through the same unvalidated channel. An attacker able to redirect or intercept a grid site's network traffic through DNS or routing manipulation can substitute both the executable pilot code and its checksum, causing arbitrary code to run in the pilot context with access to pilot proxy credentials. The fixed implementation validates the server certificate through system trust and X509_CERT_DIR or the grid certificate directory. This issue is fixed in versions 8.0.79, 9.0.22, and 9.1.10.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-61668 since 07/10/2026. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1587.003 for this issue.

Upgrading to version 8.0.79, 9.0.22 or 9.1.10 eliminates this vulnerability.
