CVE-2021-22697

Code execution via SSD object use-after-free

Published Jan 25, 2021 · Updated Aug 3, 2024

Use-after-free in EcoStruxure Power Build - Rapsody 2.1.13 and earlier allows remote attackers to execute code via a malicious SSD file. The SSD parser performs operations on an object without first validating that the object still exists, leaving a stale object reference during file processing. Exploitation requires a target to open the attacker-supplied file or visit malicious content, and successful code runs in the current process.
