Background
Drools and jBPM are open-source business rule management systems and workflow engines, respectively. They are widely used for developing and executing business processes and rules. These frameworks provide a flexible and powerful platform for automating complex business logic. However, versions prior to 6.2.0 are vulnerable to an XML external entity (XXE) attack. This vulnerability allows remote attackers to read arbitrary files or potentially exploit other unspecified impacts by manipulating a crafted BPMN2 file.
Vulnerability Detail
The vulnerability arises due to improper input validation in Drools and jBPM. Specifically, the frameworks fail to properly handle XML external entities, which can be exploited by an attacker to read sensitive files on the server or potentially execute arbitrary code. By crafting a malicious BPMN2 file, an attacker can trigger the XXE vulnerability and gain unauthorized access to files or cause other malicious actions.
How To Fix
Minimum fixed version
6.2.0.Final
This is the first release that contains the fix.

Workaround
If upgrading to the latest version is not immediately feasible, a temporary workaround is to disable the processing of external entities in the XML parser configuration. This can be achieved by modifying the configuration files or code responsible for parsing BPMN2 files. By disabling external entity processing, the vulnerability can be mitigated until a proper upgrade can be performed. However, it is strongly recommended to update to the latest version as soon as possible.
Conclusion
In conclusion, the vulnerability in Drools and jBPM versions prior to 6.2.0 allows for XML external entity (XXE) attacks, enabling remote attackers to read arbitrary files or potentially exploit other impacts. To mitigate this vulnerability, it is recommended to upgrade to version 6.2.0.Final or later. If immediate upgrade is not possible, disabling external entity processing can serve as a temporary workaround.
