Credential disclosure via reversible address-book export encryption
Published Nov 2, 2023 · Updated Sep 6, 2024
Weak encryption in address-book exports from FUJIFILM and Xerox MFP firmware allows attackers to recover stored server credentials. The export interface returns SOAP XML containing JSON entries whose credential cipher uses an easily guessed static key, MD5-derived AES keying, and reversible AES-CBC data. On default configurations, remote attackers can retrieve the export without authentication; exploitation requires stored SMB or FTP credentials.
