CVE-2019-15859 is a critical password disclosure vulnerability affecting Socomec DIRIS A-40 devices running firmware versions prior to 48250501. An unauthenticated remote attacker can exploit this flaw by accessing the /password.jsn URI on the web interface, leading to the disclosure of sensitive credentials. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability.
