CVE-2017-16632Network attack vector

Password disclosure via reversible Base64 database storage

Published Aug 11, 2021 · Updated Aug 5, 2024

Weak password storage in SapphireIMS 4097_1 allows attackers with database access to recover stored account passwords. The application writes passwords into its database after Base64 encoding, a reversible representation that provides no cryptographic protection. Exploitation requires access to the password records; the public disclosure does not identify how that database access is obtained or which accounts are exposed.
