CVE-2026-61668 (GCVE-0-2026-61668)

Vulnerability from cvelistv5 – Published: 2026-09-15 17:29 – Updated: 2026-09-15 17:29

Title

DIRAC: Pilot code downloaded over unverified HTTPS connection

Summary

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.

Severity

GHSA-VG99-GR89-QHW9

Vulnerability from github – Published: 2026-07-13 18:37 – Updated: 2026-07-13 18:37

Summary

DIRAC: Pilot code downloaded over unverified HTTPS connection

Details

Summary

The second stage pilot (pilot.tar) is downloaded by the initial wrapper script without any verification of the webservers' SSL certificate and the contained script is subsequently executed. The checksum is tested, but the reference checksum file is downloaded over the same unvalidated channel.

Details

The pilot wrapper downloads and executes the main second stage pilot script, but the SSL validation on this connection is explicitly disabled (to match old python < 2.7.9 behaviour): https://github.com/DIRACGrid/DIRAC/blob/integration/src/DIRAC/WorkloadManagementSystem/Utilities/PilotWrapper.py#L292-L296

This means that the second stage pilot code is not verified in any way and could potentially be altered by a man-in-the-middle attack to execute arbitrary code in the pilot context (i.e. with access to the pilot proxy/credentials).

The HTTPS connection should be validated against both the system certificates and $X509_CERT_DIR and fail if neither validate correctly.

Impact

This would require a man-in-the-middle style attack against a grid site's network (i.e. changing the DNS or routing to redirect the pilot's connection); this is likely to be difficult which probably limits the potential impact.

The checksum is tested, but the reference checksum file is downloaded over the same unvalidated channel.\n\n### Details\nThe pilot wrapper downloads and executes the main second stage pilot script, but the SSL validation on this connection is explicitly disabled (to match old python \u003c 2.7.9 behaviour):\nhttps://github.com/DIRACGrid/DIRAC/blob/integration/src/DIRAC/WorkloadManagementSystem/Utilities/PilotWrapper.py#L292-L296\n\nThis means that the second stage pilot code is not verified in any way and could potentially be altered by a man-in-the-middle attack to execute arbitrary code in the pilot context (i.e. with access to the pilot proxy/credentials).\n\nThe HTTPS connection should be validated against both the system certificates and $X509_CERT_DIR and fail if neither validate correctly.\n\n### Impact\nThis would require a man-in-the-middle style attack against a grid site\u0027s network (i.e. changing the DNS or routing to redirect the pilot\u0027s connection); this is likely to be difficult which probably limits the potential impact.\n\n### Patched versions:\nhttps://pypi.org/project/DIRAC/8.0.79/\nhttps://pypi.org/project/DIRAC/9.0.22/\nhttps://pypi.org/project/DIRAC/9.1.10/",

  "details": "### Summary\nThe second stage pilot (pilot.tar) is downloaded by the initial wrapper script without any verification of the webservers\u0027 SSL certificate and the contained script is subsequently executed. The checksum is tested, but the reference checksum file is downloaded over the same unvalidated channel.\n\n### Details\nThe pilot wrapper downloads and executes the main second stage pilot script, but the SSL validation on this connection is explicitly disabled (to match old python \u003c 2.7.9 behaviour):\nhttps://github.com/DIRACGrid/DIRAC/blob/integration/src/DIRAC/WorkloadManagementSystem/Utilities/PilotWrapper.py#L292-L296\n\nThis means that the second stage pilot code is not verified in any way and could potentially be altered by a man-in-the-middle attack to execute arbitrary code in the pilot context (i.e. with access to the pilot proxy/credentials).\n\nThe HTTPS connection should be validated against both the system certificates and $X509_CERT_DIR and fail if neither validate correctly.\n\n### Impact\nThis would require a man-in-the-middle style attack against a grid site\u0027s network (i.e. changing the DNS or routing to redirect the pilot\u0027s connection); this is likely to be difficult which probably limits the potential impact.\n\n### Patched versions:\nhttps://pypi.org/project/DIRAC/8.0.79/\nhttps://pypi.org/project/DIRAC/9.0.22/\nhttps://pypi.org/project/DIRAC/9.1.10/",
