CVE-2018-18894Network attack vector

Unauthenticated file disclosure via directory traversal

Published Mar 10, 2020 · Updated Aug 5, 2024

Directory traversal in Lexmark embedded web servers before 2018-12-18 allows remote attackers to read sensitive device files. The embedded web server accepts crafted paths that escape the intended directory and expose configuration or operating-system information. Exploitation requires only network access to the device web interface and no authentication; the reported impact is confidentiality loss without demonstrated modification or service interruption.
