Tecnomatix Plant Simulation V2302: Stack-based Buffer Overflow
CVE-2024-41170 is a high-severity stack-based buffer overflow vulnerability in Tecnomatix Plant Simulation V2302 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. The record lists version V2302.0015 as the first without the flaw, so updating Tecnomatix Plant Simulation V2302 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.17% 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 Tecnomatix Plant Simulation V2302 to V2302.0015 or a later version.
- Update Tecnomatix Plant Simulation V2404 to V2404.0004 or a later version.
- Update tecnomatix_plant_simulation to 2302.0015 or 2404.0004, whichever matches your release line, or a later version.
- 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 vulnerability has been identified in Tecnomatix Plant Simulation V2302 (All versions < V2302.0015), Tecnomatix Plant Simulation V2404 (All versions < V2404.0004). The affected applications contain a stack based overflow vulnerability while parsing specially crafted SPP files. This could allow an attacker to execute code in the context of the current process.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Stack-based Buffer Overflow
The product writes past the end of a buffer that was allocated on the stack.
How developers prevent this class of flaw
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking. D3-SFCV (Stack Frame Canary Validation) from D3FEND discusses canary-based detection in detail.
- Use an abstraction library to abstract away risky APIs. Not a complete solution.
- Implement and perform bounds checking on input.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
