CVE-2023-48704 is a heap buffer overflow vulnerability in ClickHouse, an open-source column-oriented database management system. An unauthenticated attacker can exploit this by sending a specially crafted payload to the native interface (port 9000/tcp), triggering a bug in the Gorilla codec's decompression logic, which crashes the ClickHouse server. This vulnerability has a CVSS score of 7.5 (HIGH), indicating a network-based attack with low complexity, no privileges or user interaction required, and a high impact on availability (denial of service). While patches are available in ClickHouse Cloud version 23.9.2.47551 and specific ClickHouse versions, there is currently no evidence of active exploitation, public exploit code, or significant community discussion.
