CVE-2019-19991Network attack vector

Authenticated script execution via four reflected inputs

Published Feb 26, 2020 · Updated Aug 5, 2024

Reflected XSS in Selesta Visual Access Manager 4.15.0 through 4.29 allows remote authenticated users to inject web script through four PHP pages. The four endpoints return attacker-controlled request data in generated HTML without neutralizing script-capable content; public records do not name the affected parameters. Exploitation requires a valid account and victim interaction, allowing script execution in the VAM web origin with limited data access or modification.
