CVE-2021-41155Public exploitNetwork attack vector

Arbitrary SQL execution via unsanitized morder parameter

Published Oct 18, 2021 · Updated Aug 4, 2024

SQL injection in Tuleap allows remote authenticated users with CVS repository read access to execute arbitrary SQL queries. The CVS revisions browser incorporates the user-controlled morder GET parameter into its revision-order SQL clause without neutralizing SQL syntax. CVS read access is required; affected Community and Enterprise releases permit injected statements to read or modify database data or interrupt service.
