Description

Rockwell Automation Connected Components Workbench v12.00.00 and prior does not sanitize paths specified within the .ccwarc archive file during extraction. This type of vulnerability is also commonly referred to as a Zip Slip. A local, authenticated attacker can create a malicious .ccwarc archive file that, when opened by Connected Components Workbench, will allow the attacker to gain the privileges of the software. If the software is running at SYSTEM level, the attacker will gain admin level privileges. User interaction is required for this exploit to be successful.

Understanding This Vulnerability

This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.

The severity rating (MEDIUM) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.

If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.

Workarounds

Users who are unable to update are directed towards risk mitigation strategies provided below, and are encouraged, when possible, to combine these with Rockwell Automation’s general security guidelines to employ multiple strategies simultaneously.
If upgrade is not possible, Rockwell Automation recommends deploying the following mitigations:
Run Connected Components Workbench as a User, not as an Administrator, to minimize the impact of malicious code on the infected system.
Do not open untrusted .ccwarc, files with Connected Components Workbench. Employ training and awareness programs to educate users on the warning signs of a phishing or social engineering attack.
Use of Microsoft AppLocker or other similar allow list applications can help mitigate risk. Information on using AppLocker with Rockwell Automation products is available at KnowledgeBase Article QA17329 (login required).
Ensure the least-privilege user principle is followed, and user/service account access to shared resources (such as a database) is only granted with a minimum number of rights as needed.

For more information, please see the industrial security advisory from Rockwell Automation.

Solutions

Rockwell Automation recommends users of the affected software update to an available software revision (Connected Components Workbench v13.00.00 or later) that addresses the associated risk.
