Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.\n","title":"General security recommendations"},{"category":"other","text":"ABB has a rigorous internal cyber security continuous improvement process which involves regular testing with industry leading tools and periodic assessments to identify potential product issues. Occasionally an issue is determined to be a design or coding flaw with implications that may impact product cyber security.\n\nWhen a potential product vulnerability is identified or reported, ABB immediately initiates our vulnerability handling process. This entails validating if the issue is in fact a product issue, identifying root causes, determining what related products may be impacted, developing a remediation, and notifying end users and governmental organizations.\n\nThe resulting Cyber Security Advisory intends to notify customers of the vulnerability and provide details on which products are impacted, how to mitigate the vulnerability or explain workarounds that minimize the potential risk as much as possible. The release of a Cyber Security Advisory should not be misconstrued as an affirmation or indication of an active threat or ongoing campaign targeting the products mentioned here. If ABB is aware of any specific threats, it will be clearly mentioned in the communication.\n\nThe publication of this Cyber Security Advisory is an example of ABB’s commitment to the user community in support of this critical topic. Responsible disclosure is an important element in the chain of trust we work to maintain with our many customers. The release of an Advisory provides timely information which is essential to help ensure our customers are fully informed.","title":"Purpose"},{"category":"faq","text":"What causes the vulnerability?\n- The vulnerability is caused by a local attacker gaining elevated privileges through Path Traversal of http server in the Mint Workbench I.\n\nWhat is Mint Workbench I?\n- Mint Workbench I is a comprehensive Windows GUI for MINT programming and provides a user-friendly interface for commissioning Micro Flex and Moti Flex servo drives, to guide users to complete servo and motor configuration and commission.\n\nWhat might an attacker use the vulnerability to do?\n- A local attacker could acquire privileges to cause confidentiality impact of system files by arbitrarily reading files of system.\n\nHow could an attacker exploit the vulnerability?\n- An attacker could try to exploit vulnerability by http Path Traversal. This would require that the attacker has access to the system locally. Recommended practices help mitigate such attacks, see section Mitigating Factors above.\n\nCould the vulnerability be exploited remotely? \n- No, to exploit this vulnerability an attacker would need to be locally logged into an affected system node.\n\nCan functional safety be affected by an exploit of this vulnerability?\n- Functional safety is not affected by this vulnerability.\n\nWhat does the update do?\n- There are no updates This product has very few remaining users and is scheduled for discontinuation by end of 2026 internationally (out of China), and discontinuation by end of 2027 in China. \n\nWhen this security advisory was issued, had this vulnerability been publicly disclosed?\n- No, ABB received information about this vulnerability through responsible disclosure.\n\nWhen this security advisory was issued, had ABB received any reports that this vulnerability was being exploited?\n- No, ABB had not received any information indicating that this vulnerability had been exploited when this security advisory was originally issued.","title":"Frequently Asked Questions"}],"publisher":{"category":"vendor","name":"ABB PSIRT","namespace":"https://www.abb.com/global/en/company/about/cybersecurity/alerts-and-notifications"},"references":[{"category":"self","summary":"ABB CYBERSECURITY ADVISORY - PDF Version ","url":"https://search.abb.com/library/Download.aspx?DocumentID=9AKK108473A3188&LanguageCode=en&DocumentPartId=&Action=Launch"},{"category":"self","summary":"ABB CYBERSECURITY ADVISORY - CSAF Version ","url":"https://psirt.abb.com/csaf/2026/9akk108473a3188.json"}],"title":"Mint Workbench I Path traversal Vulnerability","tracking":{"current_release_date":"2026-09-22T00:30:00.000Z","generator":{"date":"2026-09-23T04:23:19.869Z","engine":{"name":"Secvisogram","version":"2.6.12"}},"id":"9AKK108473A3188","initial_release_date":"2026-09-22T00:30:00.000Z","revision_history":[{"date":"2026-09-22T00:30:00.000Z","legacy_version":"A","number":"1","summary":"Initial version"}],"status":"final","version":"1"}},"product_tree":{"branches":[{"branches":[{"branches":[{"category":"product_version_range","name":"<=5876 ","product":{"name":"ABB Mint Workbench I <=5876 ","product_id":"AV1"}}],"category":"product_name","name":"Mint Workbench I"}],"category":"vendor","name":"ABB"}]},"vulnerabilities":[{"cve":"CVE-2026-19438","cwe":{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')"},"notes":[{"category":"description","text":"A vulnerability exists in the Mint Workbench I, the versions listed as affected in the advisory.
