Vulnerability from csaf_abb - Published: 2025-04-10 08:30 - Updated: 2025-04-10 08:30Summary
ABB MV Drives Affected by CODESYS RTS (Runtime System) Vulnerabilities
Notes
Summary
Multiple vulnerabilities regarding the CODESYS Runtime System from CODESYS Group have been publicly reported. CODESYS Runtime System v.3.5.15.0 is utilized in the firmware of ABB MV ACS6080 and ACS5000 drives to provide IEC 61131 programming capabilities.
These vulnerabilities could lead to out-of-bound memory access. A successful exploit may result in a denial-of-service condition or arbitrary code execution.
Firmware updates are available to address the vulnerabilities in products listed as affected in this advisory.
Mitigating factors
To exploit these vulnerabilities, a successful login to the affected product is required. This can be achieved by one of the following methods:
• Connecting a computer to the Drive, that is running Drive Automation Builder (Automation Builder | ABB) or Drive Composer (Drive Composer - Software tools | ABB).
• Having access to the local network where the drive is located. In this case, an attacker could send mal-formed packets directly to the drive.
To make the attack more difficult and less likely to succeed, provide network isolation where the drive is located and ensure that no computer running Drive Automation Builder or Drive Composer is connected to the drive without proper security controls. Please refer to “General security recommendations” for further advise on how to keep drive secure.
Refer to the “General Security Recommendations” section at the end of this document for further mitigation actions.
Workarounds
For situations where the “Recommended immediate actions” are not feasible, ABB proposes the following workaround to mitigate this threat:
• Set bit 2 "Disable file download” to TRUE in the "96.102 User lock functionality" parameter.
Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. Please refer to “Impact of workaround” section to understand possible reduced functionality of the drive.
IMPORTANT: Contact a qualified and certified ABB personnel if you need more information about the parameter handling of the affected products.
Impact of workaround
This workaround restricts the updating of IEC programs, but existing IEC programs on Drives can still be used. To update an IEC program, the operator must unlock the user lock and enable file download in a protected network environment. It is highly recommended to disable file download, as vulnerabilities are more easily exploitable when file download is enabled.
WARNING: The user lock cannot be opened even by ABB if the pass code is lost.
General security recommendations
For any installation of software-related ABB products we strongly recommend the following (non-exhaustive) list of cyber security practices:
• Isolate special purpose networks (e.g. for automation systems) and remote devices behind firewalls and separate them from any general-purpose network (e.g. office or home networks).
• Install physical controls so no unauthorized personnel can access your devices, components, peripheral equipment, and networks.
• Never connect programming software or computers containing programing software to any network other than the network for the devices that it is intended for.
• Scan all data imported into your environment before use to detect potential malware infections.
• Minimize network exposure for all applications and endpoints to ensure that they are not accessible from the Internet unless they are designed for such exposure and the intended use requires such.
• Ensure all nodes are always up to date in terms of installed software, operating system, and firmware patches as well as anti-virus and firewall.
• When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). 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.
• Install the drive in a secure location that is only accessible to authorized persons.
• Install physical controls so only authorized personnel can access devices connected to the drive (computers, peripheral equipment, and networks).
• Avoid connecting computers containing Drive Automation Builder programing software to any network other than the network for the devices that it is intended for.
• Ensure security controls are followed on computers connected to the Drive. For example, updated security patches, firewall, anti-virus are installed, and only authorized Software is running. It is customer responsibility to ensure these conditions.
More information on recommended practices can be found in the reference section document: Protecting operations through cyber security: ABB Drives solutions.

ABB has addressed the CODESYS Runtime System vulnerabilities by disabling the IEC online programming communication by default. As a result, CODESYS communication between affected products and the ABB Automation Builder or ABB Drive Application Builder tools is disabled.\nIt should be noted that the CODESYS application continues to run on the Drive and if it is necessary to establish communication with CODESYS RTS, for example to debug the CODESYS application, this is possible through the drive parameter configuration. Open the user lock via the \"96.02 Pass code\" parameter and make sure that bit 9 \"Enable online IEC programming\" is set to TRUE in the \"96.102 User lock functionality\" parameter.\n\n\nIMPORTANT: After this task, be sure to disable CODESYS communication by setting the bit back to FALSE.\nA future firmware update is planned to update the CODESYS RTS library, which will further strengthen defenses for the vulnerabilities mentioned above.\n\n\nFor situations where firmware update is not feasible, please refer to \u201cWorkarounds\u201d section.",
