CVE-2020-1772Network attack vector

Password-reset token disclosure via wildcard matching

Published Mar 27, 2020 · Updated Sep 16, 2024

Wildcard injection in OTRS 7.0.15 and earlier allows remote attackers to retrieve other users' password-reset tokens. The Lost Password request handler accepts wildcard characters in the Token value and matches valid tokens instead of requiring an exact token. Exposure requires a reset token generated for another user; affected Community Edition branches are 5.0.41 and earlier and 6.0.26 and earlier.
