Code execution via use-after-free in JT parsing
Published Dec 14, 2021 · Updated Aug 4, 2024
Use-after-free in Jt1001.dll in Siemens JT Open, JT Utilities, and Solid Edge allows attackers to execute code via crafted JT files. The JT parser performs operations on an object without first validating that the object still exists, allowing freed memory to be reused. Exploitation requires a user to open an attacker-controlled JT file, and resulting code runs in the current process.

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.
