CVE-2020-5602

Information disclosure via unsafe XML entity resolution

Published Jun 30, 2020 · Updated Aug 4, 2024

Mitsubishi FA engineering software with affected versions through the listed releases allows attackers to disclose files via crafted project or configuration files. XML parsing resolves external entities from attacker-controlled input and sends any user-readable file to an external destination. Exploitation requires a user to open the malicious file; confidentiality loss is demonstrated, while integrity and availability impact are not reported.
