CVE-2019-11642 : Vulnerability Insights and Analysis

A security flaw has been detected in the OneShield Policy (Dragon Core) framework versions prior to 5.1.10. This vulnerability allows authenticated remote attackers to tamper with log files by injecting harmful data into headers or form elements. The injected data is then executed through a client-side debug console. The successful exploitation of this vulnerability relies on the presence of the debug console and Java Bean in the deployed application.

Understanding CVE-2019-11642

A log poisoning vulnerability has been discovered in the OneShield Policy (Dragon Core) framework before 5.1.10. Authenticated remote adversaries can poison log files by entering malicious payloads in either headers or form elements. These payloads are then executed via a client-side debugging console. This is predicated on the debugging console and Java Bean being made available to the deployed application.
