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 vulnerabilities are caused by:\n - Wrong configuration in T-MAC Plus IIS Server.\n - Wrong configuration of privileges of users.\n - Lack of encryption in communication protocol.\n\nWhat is T-MAC Plus?\n- T-MAC Plus is a Terminal Management System (TMS) that handles the different operations (receipt and dispatch product, access control, product movement in the tank farm, …) in a terminal. It is applicable to different type of products such as chemical and petroleum terminals, pipeline or refinery tankage, bulk plants or hydrogen terminals. \n\n The following components are affected: \n - TMAC Plus Web application\n - Communication protocol with Card Readers\n\nWhat might an attacker use the vulnerability to do?\n- An attacker who successfully exploited this vulnerability could cause the affected system node to stop or become inaccessible and allow the attacker to insert and run arbitrary code.\n\nHow could an attacker exploit the vulnerability?\n- An attacker could try to exploit the vulnerability by creating a specially crafted message and sending the message to an affected system node. This would require that the attacker has access to the system network, by connecting to the network directly. Recommended practices help mitigate such attacks, see section Mitigating Factors.\n\nCould the vulnerability be exploited remotely? \n- No, to exploit this vulnerability an attacker would need to have physical access to an affected system node.\n\nCan functional safety be affected by an exploit of this vulnerability?\n- While these vulnerabilities primarily impact confidentiality, integrity, and availability, they do not directly affect functional safety in the traditional sense\n\nWhat does the update do?\n- The update removes the vulnerability by modifying the way that the T-MAC Plus web application and the communication protocol are configured.\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.\n", "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=9AKK108472A7840&LanguageCode=en&DocumentPartId=&Action=Launch" }, { "category": "self", "summary": "ABB CYBERSECURITY ADVISORY - CSAF Version ", "url": "https://psirt.abb.com/csaf/2026/9akk108472a7840.json" } ], "title": "Vulnerabilities in T-MAC Plus", "tracking": { "current_release_date": "2026-06-03T00:30:00.000Z", "generator": { "date": "2026-06-02T07:26:27.199Z", "engine": { "name": "Secvisogram", "version": "2.6.2" } }, "id": "9AKK108472A7840", "initial_release_date": "2026-06-03T00:30:00.000Z", "revision_history": [ { "date": "2026-06-03T00:30:00.000Z", "legacy_version": "A", "number": "1", "summary": "Initial version." } ], "status": "final", "version": "1" } }, "product_tree": { "branches": [ { "branches": [ { "branches": [ { "category": "product_version", "name": "4.0-24", "product": { "name": "ABB T-MAC Plus 4.0-24", "product_id": "AV1" } }, { "category": "product_version", "name": "4.0-25", "product": { "name": "ABB T-MAC Plus 4.0-25", "product_id": "FX1" } } ], "category": "product_name", "name": "T-MAC Plus" } ], "category": "vendor", "name": "ABB" } ] }, "vulnerabilities": [ { "cve": "CVE-2025-14771", "cwe": { "id": "CWE-552", "name": "Files or Directories Accessible to External Parties" }, "notes": [ { "category": "description", "text": "File Disclosure in ABB T-MAC Plus web application allows authenticated users to exfiltrate files containing sensitive information via crafted HTTP GET request.", "title": "CVE description" } ], "product_status": { "fixed": [ "FX1" ], "known_affected": [ "AV1" ] }, "references": [ { "category": "external", "summary": "NVD - CVE-2025-14771", "url": "https://nvd.nist.gov/vuln/detail/CVE-2025-14771" } ], "remediations": [ { "category": "vendor_fix", "details": "ABB has investigated these vulnerabilities to provide adequate protection to customers.
