CVE-2023-3512Network attack vector

Arbitrary file disclosure via Download file traversal

Published Oct 4, 2023 · Updated Sep 19, 2024

Relative path traversal in Setelsa Security ConacWin CB 3.8.2.2 and earlier allows remote attackers to download arbitrary system files. The Download file parameter uses attacker-controlled relative path segments without confining the resolved path to the intended directory. No credentials or user interaction are required; disclosure is limited to files readable by the server process, with no reported write or service-interruption capability.
