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
This vulnerability in Apache IoTDB arises from improper validation of length fields in its RPC service. An attacker can send a crafted malformed Thrift frame that causes the system to allocate an excessive amount of memory, leading to an OutOfMemoryError and denial of service. The affected versions include all releases before 1.3.8 and from 2.0.0 up to 2.0.9. The issue is fixed in version 2.0.10.
Potential Impact
A remote unauthenticated attacker can cause a denial of service by crashing the Apache IoTDB server through excessive memory allocation. This results in service disruption but does not impact confidentiality or integrity according to the available data.
Mitigation Recommendations
Users should upgrade Apache IoTDB to version 2.0.10 or later, which contains the fix for this vulnerability. Patch status is confirmed by the recommendation to upgrade; no other mitigations are indicated.
