Parasolid V35.0: Out-of-bounds Read

Published Updated By the CyberSecBulletin desk

CVE-2023-49125 is a high-severity out-of-bounds read vulnerability in Parasolid V35.0 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 V35.0.263 as the first without the flaw, so updating Parasolid V35.0 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.2% 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 Parasolid V35.0 to V35.0.263 or a later version.
  2. Update Parasolid V35.1 to V35.1.252 or a later version.
  3. Update Parasolid V36.0 to V36.0.198 or a later version.
  4. Read the advisory on cert-portal.siemens.com for workarounds and exact fixed builds.
  5. 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 Parasolid V35.0 (All versions < V35.0.263), Parasolid V35.1 (All versions < V35.1.252), Parasolid V36.0 (All versions < V36.0.198), Solid Edge SE2023 (All versions < V223.0 Update 11), Solid Edge SE2024 (All versions < V224.0 Update 3). The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted files containing XT format. 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: Out-of-bounds Read

The product reads data past the end, or before the beginning, of the intended buffer.

How developers prevent this class of flaw

  • Use a language that provides appropriate memory abstractions.
