MediumCVSS 6.3Exploitation Probability (EPSS)
Low risk27th percentile - higher than 27% of all known CVEs
Summary
A vulnerability was detected in Open Asset Import Library Assimp 17c12da. This affects the function Assimp::MDLImporter::AddBonesToNodeGraph_3DGS_MDL7 of the file code/AssetLib/MDL/MDLLoader.cpp of the component Node Parser. The manipulation of the argument bones_num results in heap-based buffer overflow. The attack can be executed remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
Risk Assessment
Heap-based buffer overflow could allow an attacker to execute arbitrary code or cause application crash, potentially leading to system integrity compromise.
Recommendation
It is recommended to update the Assimp library to the latest version if available and restrict processing of untrusted MDL files.
