What is CVE-2018-12533?

The JBoss RichFaces framework versions 3.1.0 to 3.3.4 are susceptible to an expression language injection vulnerability. This flaw allows unauthenticated remote attackers to inject EL expressions and potentially execute arbitrary Java code. This can occur when the application processes paths that include a /DATA/ substring, exposing an org.richfaces.renderkit.html.Paint2DResource$ImageData object. Such exploitation poses a risk of unauthorized access and manipulation of data, leading to severe security breaches.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
