CWEhttps://cwe.mitre.org/data/definitions/917.html

JBoss RichFaces 3.1.0 through 3.3.4 allows unauthenticated remote attackers to inject expression language (EL) expressions and execute arbitrary Java code via a /DATA/ substring in a path with an org.richfaces.renderkit.html.Paint2DResource$ImageData object, aka RF-14310.

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.
