Autodesk Trueview: Out-of-bounds Read
CVE-2022-27523 is a high-severity out-of-bounds read vulnerability in Autodesk Trueview, with a CVSS 3.1 base score of 7.1 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 Trueview versions: 2022.1.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.44% chance of exploitation within 30 days, higher than 74% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Dwg Trueview to 2019.1.4 or 2020.1.5 or 2021.1.2 or 2022.1.2, 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.
