The BeanShell components of IRISNext through 9.8.28 allow execution of arbitrary commands on the target server by creating a custom search (or editing an existing/predefined search) of the documents. The search components permit adding BeanShell expressions that result in Remote Code Execution in the context of the IRISNext application user, running on the web server.

Weakness

The product constructs all or part of an expression language (EL) statement in a framework such as a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed.
