Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

DIRAC 是一种 interware（中间件），即为分布式计算提供支持的软件框架。在 8.0.79、9.0.22 和 9.1.10 版本之前， 中的 使用 来下载第二阶段的 归档文件，且未进行 TLS 证书验证，同时也通过这条未经验证的通道下载对应的校验和（checksum）。 攻击者若能够通过 DNS 或路由操纵来重定向或截获网格站点（grid site）的网络流量，就可以同时替换可执行的 pilot 代码及其校验和，从而让任意代码在 pilot 上下文中运行，并获得对 pilot 代理凭据的访问权限。 修复后

Vulnerability Title
DIRAC: Pilot code downloaded over unverified HTTPS connection
Source: CVE Program / CVE List V5
Vulnerability 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, 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.
