Summary

CVE-2025-11277 is a low-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Assimp Assimp. Its CVSS base score is 1.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 13th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-16 (Memory Protection) — see the control section below for these in your framework.

Vulnerability Data

A weakness has been identified in Open Asset Import Library Assimp 6.0.2. This affects the function Q3DImporter::InternReadFile of the file assimp/code/AssetLib/Q3D/Q3DLoader.cpp. Executing a manipulation can lead to heap-based buffer overflow. The attack needs to be launched locally. The exploit has…

MITRE ATT&CK Enterprise TechniquesAI

T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
Why these techniques?

Heap-based buffer overflow in Assimp Q3DImporter allows exploitation via malicious local Q3D files for client-side code execution in applications using the library.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of untrusted file input (Q3D data) before processing in Q3DImporter::InternReadFile, blocking the malformed content that triggers the heap overflow.

prevent

Enforces memory protections (e.g., ASLR, guard pages, bounds checking) that mitigate exploitation of the CWE-119/CWE-122 heap buffer overflow in Assimp.

prevent

Requires timely application of patches or updates to Assimp once the buffer-overflow flaw in Q3DLoader.cpp is corrected by the vendor.

detects

Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.

prevents

Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.

prevents

Application security requirements can specify memory-safety rules, but do not prescribe implementation details.

prevents

Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.

prevents

Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.

none

Change management ensures controlled deployment of fixes for discovered heap-overflow vulnerabilities.
