CVE-2022-40647
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of Ansys SpaceClaim 2022 R1. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of X_B files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-17558.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAnsys SpaceClaim 2022 R1 contains an out-of-bounds read vulnerability when parsing X_B files due to lack of proper validation of user-supplied data. An attacker can exploit this by enticing a user to open a malicious X_B file, allowing arbitrary code execution in the context of the current process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify if Ansys SpaceClaim is installedCheck for SpaceClaim installation directory (commonly at C:\Program Files\ANSYS Inc\SpaceClaim or C:\Program Files\ANSYS\SpaceClaim) or search for 'SpaceClaim' in Windows Programs and FeaturesAffected if Ansys SpaceClaim 2022 is installed on the system
-
Determine installed SpaceClaim versionOpen SpaceClaim and go to Help > About, or check the version in Add/Remove Programs. Look for version information showing 2022 or 2022 R1Affected if The installed version is Ansys SpaceClaim 2022 (any 2022 release)
-
Confirm X_B file handling capability existsX_B files are native SpaceClaim geometry/script files. Check if the SpaceClaim installation includes X_B file parsers (look for file association handlers or check if the application can open .x_b files)Affected if X_B file parsing functionality is present and available in the installation
-
Check for recent X_B file processing activityReview recently opened files in SpaceClaim or check for .x_b files in recent documents, or monitor for attempts to open X_B filesAffected if X_B files have been opened or processed in the vulnerable software version
If Ansys SpaceClaim 2022 (any 2022 R1 release) is installed and X_B file parsing is enabled, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataAvoid opening untrusted X_B files from unknown sources. Implement file type restrictions and consider application isolation or sandboxing until an official vendor patch is released.
