ICS Advisory Rockwell Automation Studio 5000 Logix Designer Release DateJuly 21, 2026 Alert CodeICSA-26-202-10 Related topics: Industrial Control System Vulnerabilities , Industrial Control Systems View CSAF Summary Successful exploitation of these vulnerabilities could allow for a local attacker to execute arbitrary files, alter configurations, or execute arbitrary code. The following versions of Rockwell Automation Studio 5000 Logix Designer are affected: Studio 5000 Logix Designer V36.00 (CVE-2026-9108) Studio 5000 Logix Designer V35.00 (CVE-2026-9108, CVE-2026-9127, CVE-2026-9128) Studio 5000 Logix Designer V35.01 (CVE-2026-9108) Studio 5000 Logix Designer >=V34.00|<=V34.03 (CVE-2026-9108) Studio 5000 Logix Designer >=V33.00|<=V33.03 (CVE-2026-9108) Studio 5000 Logix Designer >=V32.00|<=V32.04 (CVE-2026-9108, CVE-2026-9127, CVE-2026-9128) Studio 5000 Logix Designer V34.00 (CVE-2026-9127) Studio 5000 Logix Designer V34.01 (CVE-2026-9127) Studio 5000 Logix Designer V33.00 (CVE-2026-9127) Studio 5000 Logix Designer V33.02 (CVE-2026-9127) Studio 5000 Logix Designer >=V34.00|<=V34.02 (CVE-2026-9128) Studio 5000 Logix Designer >=V33.00|<=V33.02 (CVE-2026-9128) CVSS Vendor Equipment Vulnerabilities v3 7.5 Rockwell Automation Rockwell Automation Studio 5000 Logix Designer Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), Incorrect Authorization, Unquoted Search Path or Element Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: United States Vulnerabilities Expand All + 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.

This can allow any authenticated user to modify the paths of external tools configured within the application. If exploited, an attacker could alter the configuration to point to a malicious executable, resulting in arbitrary code execution when any user interacts with the external tools functionality.

The executable paths specified in the external tools configuration file are not properly quoted, and because these paths contain spaces, the operating system may resolve them to unintended executables placed earlier in the search order. If exploited, an attacker could plant a malicious executable in a location within the search path, resulting in arbitrary code execution with the same permissions of the user running the application.
