Description

A maliciously crafted ABC file, when parsed through Autodesk 3ds Max, can 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.

  "executiveSummary": "An Out-of-Bounds Write vulnerability exists within Autodesk 3ds Max when parsing maliciously crafted ABC files. This memory corruption flaw arises during the file parsing phase, allowing an attacker to write data past the allocated buffer boundaries.\nSuccessful exploitation of this vulnerability can lead to application crashes, system data corruption, or the execution of arbitrary code within the security context of the current process running Autodesk 3ds Max.\nThe affected product is Autodesk 3ds Max. The risk implications are severe due to the potential for arbitrary code execution upon processing a malicious file.\nAttacker capabilities include leveraging the crafted ABC file to compromise the integrity and availability of the host application. Exploitation requires user interaction, specifically convincing a target to open or parse a maliciously crafted ABC file using the vulnerable software.",
  "technicalDetails": "The root cause of the vulnerability is an insufficient bounds check during the parsing of ABC files within Autodesk 3ds Max, resulting in an Out-of-Bounds Write condition.\nThe vulnerable component is the ABC file parser module responsible for interpreting and loading structural data from ABC format files.\nExploitation occurs when a user loads or imports a maliciously crafted ABC file into Autodesk 3ds Max. The parser processes the malformed structures within the file without properly validating size constraints or offsets against the destination memory buffer.\nAs the parsing engine reads the crafted input, it writes data outside the intended heap or stack allocation boundaries. This memory overwrite corrupts adjacent memory structures, control flow data, or heap metadata.\nDepending on the precision of the memory corruption and the layout of the process memory, an attacker can hijack the execution flow to run arbitrary shellcode or payloads in the context of the user running Autodesk 3ds Max.\nThe attack requires local execution or user interaction via file opening, as network exposure depends on how the file is delivered and processed. No authentication or elevated privileges are required to trigger the crash or initiate execution, provided the victim opens the malicious ABC file."
