CyberRota Analysis

AI-Generated

The vulnerability exists in the Flowable engine, specifically in the ProcessDiagramLayoutFactory.parseXml() method, which improperly handles XML external entity resolution during BPMN file parsing. This can allow attackers with process deployment privileges to exploit the flaw by embedding malicious DOCTYPE declarations, potentially leading to unauthorized access to local files or internal network resources. Organizations utilizing Flowable engine versions up to 8.0.0 should prioritize remediation to mitigate the risk of data exposure and internal network attacks.

Original NVD Description

Flowable flowable-engine through 8.0.0 contains an XML external entity injection vulnerability in ProcessDiagramLayoutFactory.parseXml() that fails to disable external entity resolution when parsing deployed BPMN resources. Attackers with process deployment privileges can embed DOCTYPE declarations with external entities in BPMN files to read arbitrary local files or trigger requests to internal network endpoints when diagram layout is computed.
