| Summary | XWork ParameterInterceptors bypass allows remote command execution
The OGNL extensive expression evaluation capability in this package as used in Atlassian Fisheye, Crucible, and possibly other products, uses a permissive allowlist, which allows remote attackers to modify server-side context objects and bypass the "#" protection mechanism in ParameterInterceptors via the `#context`, `#_memberAccess`, `#root`, `#this`, `#_typeResolver`, `#_classResolver`, `#_traceEvaluations`, `#_lastEvaluation`, `#_keepLastEvaluation`, and possibly other OGNL context variables, a different vulnerability than CVE-2008-6504. |
