CVE-2020-1779

Sensitive-data disclosure via unmasked dynamic-template tags

Published Feb 8, 2021 · Updated Sep 16, 2024

Information exposure in OTRS Ticket Forms allows remote authenticated users with administrator privileges to read sensitive data. Dynamic-template processing fails to mask administrator-supplied OTRS tags before expanding them, exposing values that should remain hidden. Affected releases are 6.0.40 and earlier in the 6.0.x branch, 7.0.29 and earlier in the 7.0.x branch, and 8.0.3 and earlier in the 8.0.x branch; disclosure occurs when another user interacts with the configured template.
