Description

Apache ShardingSphere-Proxy prior to 5.3.0 when using MySQL as database backend didn't cleanup the database session completely after client authentication failed, which allowed an attacker to execute normal commands by constructing a special MySQL client. This vulnerability has been fixed in Apache ShardingSphere 5.3.0.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.shardingsphere:shardingsphere-proxy, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.shardingsphere:shardingsphere-proxy to 5.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-45347 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
