CVE-2022-34967Public exploitNetwork attack vector

ODBC client abort via reachable assertion

Published Aug 3, 2022 · Updated Aug 3, 2024

Reachable assertion in MonetDB ODBC Driver 11.44.0 with Database Server 11.43.13 allows attackers to abort an ODBC client. After a nested-window query makes SQLPrepare return unexpected EOF, a later statement reaches destroyODBCStmt and asserts on its FirstStmt linkage. Exploitation requires an established ODBC connection and the documented query sequence; server compromise or data alteration is not demonstrated.
