Memory disclosure via out-of-bounds OBJ parsing
Published Mar 27, 2023 · Updated Mar 5, 2025
Out-of-bounds read in Adobe Substance 3D Stager 2.0.0 and earlier allows remote attackers to disclose memory through a malicious OBJ file. The OBJ parser fails to validate user-supplied data before reading past the end of an allocated object. Exploitation requires the current user to visit a malicious page or open the file; the disclosure can expose ASLR-relevant data and support a broader exploit chain.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <=2.0.0
- Affected versionversion=unspecified <=None
