On certain Lexmark devices that communicate with an LDAP or SMTP server, a malicious administrator can discover LDAP or SMTP credentials by changing that server's hostname to one that they control, and then capturing the credentials that are sent there. This occurs because stored credentials are not automatically deleted upon that type of hostname change.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.9, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 16 products from lexmark, from lexmark, from lexmark and 13 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2019, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For lexmark's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
