CVE-2021-44046
Description
An out-of-bounds write vulnerability exists when reading U3D files in Open Design Alliance PRC SDK before 2022.11. An unchecked return value of a function (verifying input data from a U3D file) leads to an out-of-bounds write. An attacker can leverage this vulnerability to execute code in the context of the current process.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
An out-of-bounds write in the ODA PRC SDK when processing U3D files can allow an attacker to achieve code execution.
Vulnerability
The vulnerability exists in the Open Design Alliance PRC SDK before version 2022.11. A specially crafted U3D file can trigger an out-of-bounds write because the SDK does not properly check the return value of a function that validates input data. This flaw allows writing beyond allocated memory boundaries.
Exploitation
An attacker must deliver a malicious U3D file to a user or application that uses the vulnerable SDK to parse it. No special authentication or network position is required beyond the ability to supply the file (e.g., via email, web download, or file share). The exploitation occurs when the SDK processes the crafted file, leading to memory corruption.
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. The impact is high, as it can lead to complete compromise of confidentiality, integrity, and availability of the affected system.
Mitigation
The vulnerability is fixed in ODA PRC SDK version 2022.11 [1]. Users should upgrade to this version or later. No workarounds are publicly available if the SDK cannot be updated.
