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.

Affected Software

Name Vendor Start Version End Version
Richfaces Redhat 3.1.0 3.3.4
