JT2Go: Access of Resource Using Incompatible Type
CVE-2023-38074 is a high-severity access of resource using incompatible type vulnerability in JT2Go from Siemens, 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 JT2Go versions: All versions < V14.3.0.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.47% 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 Teamcenter Visualization to 13.4.0.12 or 14.1.0.11 or 14.2.0.6 or 14.3.0.1, whichever matches your release line, or a later version.
- Update Tecnomatix Plant Simulation to 2201.0010 or 2302.0004, whichever matches your release line, or a later version.
- Read the advisory on cert-portal.siemens.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.

The underlying weakness: Access of Resource Using Incompatible Type
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
