JT Open: Stack-based Buffer Overflow

CVE-2024-37997 is a high-severity stack-based buffer overflow vulnerability in JT Open 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 V11.5 as the first without the flaw, so updating JT Open 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.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update JT Open to V11.5 or a later version.
  2. Update JT2Go to V2406.0003 or a later version.
  3. Update PLM XML SDK to V7.1.0.014 or a later version.
  4. 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 JT Open (All versions < V11.5), JT2Go (All versions < V2406.0003), PLM XML SDK (All versions < V7.1.0.014), Teamcenter Visualization V14.2 (All versions < V14.2.0.13), Teamcenter Visualization V14.3 (All versions < V14.3.0.11), Teamcenter Visualization V2312 (All versions < V2312.0008), Teamcenter Visualization V2406 (All versions < V2406.0003). The affected applications contain a stack based overflow vulnerability while parsing specially crafted XML files. This could allow an attacker to execute code in the context of the current process.

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.
