Autodesk 3ds Max: Improper Validation of Specified Quantity in Input
CVE-2022-25793 is a high-severity improper validation of specified quantity in input vulnerability in Autodesk 3ds Max, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Autodesk 3ds Max versions: Autodesk 3ds Max 2022, 2021, 2020. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.39% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update 3ds Max to 2020.3.6 or 2021.3.10, whichever matches your release line, or a later version.
- Read the advisory on autodesk.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
A Stack-based Buffer Overflow Vulnerability in Autodesk 3ds Max 2022, 2021, and 2020 may lead to code execution through the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer when parsing ActionScript Byte Code files. This vulnerability may allow arbitrary code execution on affected installations of Autodesk 3ds Max.
