|---|
| Mô tả | An XML External Entity (XXE) injection vulnerability exists in the Imp_DoneBPMN method of the JFlow workflow engine. The application processes user-supplied XML input without securely configuring the underlying XML parser. As a result, a remote attacker can craft a malicious XML payload containing external entity declarations that, when parsed by the server, may lead to:
Disclosure of arbitrary local files (e.g., /etc/passwd, configuration files, private keys);
Server-Side Request Forgery (SSRF) to interact with internal services;
Denial-of-Service (DoS) via XML bomb attacks (e.g., "Billion Laughs"). |
