Summary
A Path Traversal vulnerability was found in Apache IoTDB. An attacker can write arbitrary files anywhere the IoTDB process has write permissions using an unsafe API.
Risk Assessment
The risk involves remote arbitrary file write (e.g., scripts, configs) which could lead to privilege escalation, arbitrary code execution, or persistent data corruption.
Recommendation
Upgrade Apache IoTDB to version 2.0.10 immediately. Until then, restrict access to the unsafe API for untrusted users.
