CVE-2022-44010Network attack vector

Unauthenticated service crash via crafted HTTP request

Published Nov 23, 2023 · Updated Aug 3, 2024

Heap-based buffer overflow in the ClickHouse HTTP endpoint before 22.9.1.2603 allows remote attackers to crash the server process. ClickHouse identifies crafted HTTP request handling as the trigger but has not disclosed the specific handler, parser, or unchecked memory operation. The request requires no authentication, and successful exploitation terminates the server process and interrupts database service.
