QRadar RemoteJavaScript Deserialization
Posted by deepcore on October 20, 2020 – 4:15 pm
A Java deserialization vulnerability exists in the QRadar RemoteJavaScript Servlet. An authenticated user can call one of the vulnerable methods and cause the Servlet to deserialize arbitrary objects. An attacker can exploit this vulnerability by creating a specially crafted (serialized) object, which amongst other things can result in a denial of service, change of system settings, or execution of arbitrary code. This issue was successfully verified on QRadar Community Edition version 7.3.1.6 (7.3.1 Build 20180723171558).
