CVE-2026-44630: CWE-789 Memory Allocation with Excessive Size Value in Apache Software Foundation Apache IoTDB
Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. By sending a crafted malformed Thrift frame, an attacker can cause IoTDB to allocate an excessive amount of memory and crash with an OutOfMemoryError. This issue affects Apache IoTDB: before 1.3.8, from 2.0.0 before 2.0.9. Users are recommended to upgrade to version 2.0.10, which fixes the issue.
AI Analysis
Technical Summary
The Apache IoTDB RPC service improperly validates length fields in incoming Thrift frames. This flaw allows a remote unauthenticated attacker to send a malformed frame that triggers excessive memory allocation, resulting in an OutOfMemoryError and a denial of service condition. The vulnerability affects versions before 1.3.8 and from 2.0.0 up to 2.0.9. The vendor has addressed this issue in version 2.0.10.
Potential Impact
A remote unauthenticated attacker can cause the Apache IoTDB server to crash by exhausting memory resources, resulting in denial of service. There is no indication of code execution or data compromise from the provided information.
Mitigation Recommendations
Users should upgrade Apache IoTDB to version 2.0.10 or later, where this vulnerability is fixed. No other mitigations or workarounds are indicated in the provided data.
