Technical details

An eval injection vulnerability (CWE-95) exists in the RequestManager component of DIRAC. The 'export_getRequestCountersWeb' function in 'ReqManagerHandler.py' accepts user-provided parameters and passes them to the database layer. In 'RequestDB.py', if a 'groupingAttribute' string is unrecognized, the application prepends 'Request.' to the string and passes it to a Python 'eval()' call. An authenticated attacker can provide a crafted dunder string to break out of the intended scope and access the 'os' module, leading to arbitrary command execution as the system user. Patches are available in versions 8.0.79, 9.0.22, and 9.1.10.
