Background
Apache IoTDB is an open-source time-series database designed for storing and analyzing large-scale time-series data. It provides efficient storage and retrieval capabilities for various IoT applications. However, versions 0.12.2 to 0.12.6 and 0.13.0 to 0.13.2 of Apache IoTDB are vulnerable to a Denial of Service (DoS) attack when accepting untrusted patterns for REGEXP queries with Java 8.
Vulnerability Detail
The vulnerability in Apache IoTDB allows an attacker to exploit the REGEXP query functionality with untrusted patterns, leading to a DoS attack. By sending specially crafted REGEXP queries, an attacker can cause the database to consume excessive CPU and memory resources, resulting in the unavailability of the service. This vulnerability can be particularly impactful in production environments with high query loads.
