CVE-2024-20750
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 · uneditedSubstance3D - Designer versions 13.1.0 and earlier are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
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 · moderate confidenceSubstance3D Designer versions 13.1.0 and earlier contain an out-of-bounds read vulnerability when parsing crafted files, allowing an attacker to read past the end of allocated memory structures. This memory corruption can be leveraged to achieve arbitrary code execution in the context of the current user, requiring the victim to open a malicious file.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate Adobe Substance 3D Designer installationSearch for 'Substance 3D Designer' in system Program Files directories (e.g., C:\Program Files\Adobe\Adobe Substance 3D Designer) or check the application in the Windows Start Menu / macOS Applications folderAffected if The application is installed on the system
-
Retrieve installed version numberIn Windows: Right-click the application shortcut, select Properties, and check the Details tab for the version. On macOS: Right-click the app in Applications, select Get Info, and note the Version field. Alternatively, check the uninstall registry key at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ for an entry named 'Adobe Substance 3D Designer'Affected if The version displayed is 13.1.0 or earlier (any version below 13.1.1)
-
Confirm parsing of untrusted design files is possibleVerify whether the application is configured to open design files from external or untrusted sources. Check recent file open history or file association settings for .sbsar, .sbs, or other Substance file typesAffected if Users can or do open design files from untrusted or unknown sources, enabling the attack vector
A system is affected if Adobe Substance 3D Designer version 13.1.0 or earlier is installed and users may open crafted malicious design files with the application.
