Summary

CVE-2025-3160 is a medium-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Assimp Assimp. Its CVSS base score is 4.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 16th 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-2 (Flaw Remediation) — see the control section below for these in your framework.

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?

Out-of-bounds read vulnerability (CWE-125) in Assimp library's file handler enables exploitation for client execution when vulnerable applications or tools process attacker-controlled malformed 3D model files, potentially leading to RCE as noted in advisories.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires applying the vendor patch (a0993658f40d8e13ff5823990c30b43c82a5daf0) that eliminates the out-of-bounds read in SceneCombiner.cpp.

prevent

Requires validation of untrusted file input before Assimp::SceneCombiner::AddNodeHashes processes it, blocking the malformed data that triggers CWE-125.

prevent

Enforces memory-protection mechanisms that can contain or abort out-of-bounds reads in the file-handler component before they produce exploitable results.

detects

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

A.8.15 Logging partial match
detects

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

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.
