Summary

Sparx Enterprise Architect version 17.1 is confirmed affected, and other versions may be affected too. The XSLT Debugger's XML parser resolves external entities in crafted XML files that reference an external DTD (CWE-611). If a user loads such a file, an attacker can read arbitrary files from the victim's filesystem.

Description from the CNA

Enterprise Architect is vulnerable to XML External Entity (XXE) injection in the XSLT Debugger feature. When a user loads a crafted XML file containing a `DOCTYPE` with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 17.1 but may also affect other versions.
