CVE-2021-27471: Rockwell Automation Connected Components Workbench Path Traversal

• Severity: high (CVSS 8.6 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 2.9% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2022-03-23 · updated 2026-06-17
• Weakness: CWE-22

Description

The parsing mechanism that processes certain file types does not provide input sanitization for file paths. This may allow an attacker to craft malicious files that, when opened by Rockwell Automation Connected Components Workbench v12.00.00 and prior, can traverse the file system. If successfully exploited, an attacker could overwrite existing files and create additional files with the same permissions of the Connected Components Workbench software. User interaction is required for this exploit to be successful.

Affected products

• Rockwell Automation Connected Components Workbench: through 12.00.00
