Rockwellautomation Studio 5000 Logix Designer

CVE-2026-9108

A path traversal security issue exists within Studio 5000 Logix Designer® due to improper limitation of file paths within ACD project files. The software does not sanitize or validate file names embedded in the ACD file structure during the project opening procedure, allowing path traversal sequences to escape the intended extraction directory. If exploited, an attacker could craft a malicious ACD project file that results in arbitrary files being written to attacker-controlled locations on the file system, potentially leading to code execution.

What this means for your business

  • It affects Rockwellautomation Studio 5000 Logix Designer. It matters if your company, or a supplier that handles your data, runs it.
  • An attacker can use it only with access to the machine itself, with an ordinary user login, but only after tricking someone into an action such as opening a file or a link.
  • FIRST's prediction model gives it a 0.1% chance of attack attempts being seen in the next 30 days, ranking above 3% of all known flaws.
