CVE-2025-3015 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 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Process Injection (T1055); ranked at the 39th 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 SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-3015 is a vulnerability in the Open Asset Import Library (Assimp) version 5.4.3 that enables an out-of-bounds read. It affects the Assimp::ASEImporter::BuildUniqueRepresentation function within the file code/AssetLib/ASE/ASELoader.cpp, specifically the ASE File Handler component. The issue arises from manipulation of the mIndices argument, classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-125 (Out-of-bounds Read), with a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L).
The vulnerability can be exploited remotely by an attacker who tricks a user into processing a specially crafted ASE file, as it requires user interaction but no privileges. Successful exploitation leads to limited impacts on confidentiality, integrity, and availability, such as potential information disclosure or denial of service through memory corruption. The exploit has been publicly disclosed and may be used in attacks against applications that rely on Assimp for ASE file parsing.
Mitigation involves upgrading to Assimp version 6.0, which addresses the issue. A specific patch is available at commit 7c705fde418d68cca4e8eff56be01b2617b0d6fe, and applying it is recommended. Additional details are documented in Assimp GitHub issues #6021 and pull request #6045, along with the VulDB entry.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.
Secure engineering principles require memory-safe design and coding that structurally avoids buffer-boundary violations.
Process isolation confines the effects of an out-of-bounds read to the compromised process.
Input validation directly enforces bounds checking that stops out-of-bounds reads/writes from being introduced or reached.
Memory protection restricts exploitation impact of buffer overflows without eliminating the underlying coding flaw.

Secure SDLC practices (bounds checking, safe APIs, reviews) directly prevent this class of flaw.
Vulnerability scanning and code analysis directly surface buffer-boundary flaws.
Receiving and triaging vulnerability disclosures commonly includes buffer-related reports.
Developer training on secure coding reduces introduction of memory-buffer errors.
Patching replaces vulnerable code containing buffer-boundary defects.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.
Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.
Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.
Application security requirements can specify memory-safety rules, but do not prescribe implementation details.
Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.
Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.
