CVE-2024-23120

Un archivo STP creado con fines malintencionados cuando se analiza en ASMIMPORT228A.dll a través de Autodesk AutoCAD puede forzar una escritura fuera de los límites. Un actor malintencionado puede aprovechar esta vulnerabilidad para provocar un bloqueo, escribir datos confidenciales o ejecutar código arbitrario en el contexto del proceso actual.

A maliciously crafted STP and STEP file, when parsed in ASMIMPORT228A.dll and ASMIMPORT229A.dll through Autodesk AutoCAD, may force an Out-of-Bounds Write vulnerability. A malicious actor may leverage this vulnerability to cause a crash, cause data corruption, or execute arbitrary code in the context of the current process.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Autodesk AutoCAD. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of STEP files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process.
