Input validation issue in POWER EGG(Ver 2.0.1, Ver 2.02 Patch 3 and earlier, Ver 2.1 Patch 4 and earlier, Ver 2.2 Patch 7 and earlier, Ver 2.3 Patch 9 and earlier, Ver 2.4 Patch 13 and earlier, Ver 2.5 Patch 12 and earlier, Ver 2.6 Patch 8 and earlier, Ver 2.7 Patch 6 and earlier, Ver 2.7 Government Edition Patch 7 and earlier, Ver 2.8 Patch 6 and earlier, Ver 2.8c Patch 5 and earlier, Ver 2.9 Patch 4 and earlier) allows remote attackers to execute EL expression on the server via unspecified vectors.

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.
