Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

DIRAC 是一个“中间件”（interware），即用于分布式计算环境的软件框架。在 8.0.79、9.0.22 和 9.1.10 版本之前， 文件中的 函数会将经过身份验证但由调用者控制的 参数传递给 文件中的 函数。如果该参数的值未被识别，系统会尝试将其作为 Python 代码对 Request 对象进行解析和执行。攻击者可利用精心构造的双下划线（dunder）属性表达式（如 等链式调用）访问操作系统层面的函数，从而在以 DIRAC 服务运行账户权限下执行任意命令。 成功利用该漏洞可能导致以下后果： 泄露 配

Vulnerability Title
DIRAC: RCE in RequestManager due to eval on untrusted input
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, the RequestManagementSystem/Service/ReqManagerHandler.py export_getRequestCountersWeb function passes an authenticated caller-controlled groupingAttribute to RequestManagementSystem/DB/RequestDB.py getRequestCountersWeb. An unrecognized value is resolved against the Request object and evaluated as Python code, allowing a crafted dunder attribute expression to reach operating-system functions and execute commands 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.
