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.
Support: For additional instructions and support please contact your local ABB service organization. For contact information, see www.abb.com/contactcenters.

Purpose: 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.
When 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.
The 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.
The 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.
Frequently asked questions: What causes the vulnerability?
- Refer to section “Vulnerability severity and details“.
What is Wibu CodeMeter?
- Wibu CodeMeter is a technology of Wibu-Systems providing secure protection and effective license management of software and digital content.
What are the affected ABB tools (Automation Builder, Drive Application Builder, Virtual Drive, Virtual DrivePlus)?
- All mentioned tools are using Wibu CodeMeter for implementation of license enforcement:
- Automation Builder is the programming and commissioning tool mainly for the ABB PLC AC500 and the operator panels CP600.
- Drive Application Builder is the programming and commissioning tool ABB’s IEC programmable Drives (mainly ACS880 series).
- Virtual Drive enhances Drive Composer Pro by enabling offline configuration of ABB drives without requiring physical hardware. Supported drives include ACS380, ACS380-E, ACS480, ACS580 and ACS880 primary control program.
- ACS880 Virtual DrivePlus is a digital twin of ACS880 product series, running on a desktop in virtual time and designed for high-fidelity EMT (Electromagnetic Transient) simulations of a drive or drive systems.
What might an attacker use the vulnerability to do?
- An attacker who successfully exploited these vulnerabilities could
- allow arbitrary files to be deleted with system privileges (CVE-2026-81572),
- read potentially sensitive configuration data and overwrite selected values in Server.ini (CVE-2026-81573),
- crash CodeMeter and disclose sensitive information such as process memory and stack canaries (CVE-2026-81574),
- crash CodeMeter (CVE-2026-81575), or
- read potentially sensitive license information (CVE-2026-81576).
How could an attacker exploit the vulnerability?
- Refer to section “Vulnerability severity and details“.
Could the vulnerability be exploited remotely?
- Yes, an attacker who has network access to an affected system node could exploit the vulnerabilities. Recommended practices include that process control systems are physically protected, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed.
When this security advisory was issued, had this vulnerability been publicly disclosed?
- Yes, the vulnerabilities have been publicly disclosed.
When this security advisory was issued, had ABB received any reports that this vulnerability was being exploited?
- No, ABB had not received any information indicating that this vulnerability had been exploited when this security advisory was originally issued
cmu.exe --create-io --file C: creates a predictable temporary file under C:\CM-Stick. The directory and file paths are not properly checked for NTFS reparse points, such as junctions or symbolic links, before file operations are performed. A local attacker can create a junction at the temporary file that points to an arbitrary system path. Because CodeMeter Runtime runs with System privileges, this could allow arbitrary files to be deleted with System privileges and potentially enable local privilege escalation.

If CodeMeter Runtime is configured as a server, the configuration command handler does not enforce networkorigin restrictions. Commands intended only for local or same-network clients can therefore be executed by arbitrary remote peers. An attacker can read potentially sensitive configuration data and overwrite selected values in Server.ini. This does include the hash of the credentials for the CodeMeter WebAdmin, enabling WebAdmin takeover. CodeMeter Runtime is only affected by the vulnerabilities listed below if it is configured as a server. This is not the default. To verify the setting, check the profiling value IsNetworkServer: - IsNetworkServer=1: configured as a server (affected). - IsNetworkServer=0: not configured as a server.
CWE-59 - Improper Link Resolution Before File Access ('Link Following')Affected products

CVE-2026-81572
Known affected
4 products, the same list as for
CVE-2026-81572
The logger does not sanitize input strings in certain cases, allowing an attacker to inject printf-style format specifiers. This can be used to reliably crash CodeMeter and disclose sensitive information such as process memory and stack canaries. The attack works locally, for example by using cmu --set-proxy to set the proxy value, and remotely when combined with CVE-2026-81573 by setting General.ProxyServer and then triggering this vulnerability. CodeMeter Runtime is only affected by the vulnerabilities listed below if it is configured as a server. This is not the default. To verify the setting, check the profiling value IsNetworkServer: - IsNetworkServer=1: configured as a server (affected). - IsNetworkServer=0: not configured as a server
CWE-134 - Use of Externally-Controlled Format StringAffected products
Fixed
1 product, the same list as for
CVE-2026-81572
Known affected
4 products, the same list as for
CVE-2026-81572
If configured as a server, CodeMeter Runtime accepts requests with opcode 0x5e, which contain the data length and the data itself. Missing bounds checking on the data length value can lead to out of bounds reads, causing a segmentation fault that ultimately crashes the CodeMeter Runtime. CodeMeter Runtime is only affected by the vulnerabilities listed below if it is configured as a server. This is not the default. To verify the setting, check the profiling value IsNetworkServer: - IsNetworkServer=1: configured as a server (affected). - IsNetworkServer=0: not configured as a server.
CWE-130 - Improper Handling of Length Parameter InconsistencyAffected products
Fixed
1 product, the same list as for
CVE-2026-81572
Known affected
4 products, the same list as for
CVE-2026-81572
If configured as a server, CodeMeter Runtime issues handles per connection and relies on a cryptographically weak SID as sole authenticator. An attacker can brute-force the SID, recover another session's handle number, and read license information belonging to another handle. CodeMeter Runtime is only affected by the vulnerabilities listed below if it is configured as a server. This is not the default. To verify the setting, check the profiling value IsNetworkServer: - IsNetworkServer=1: configured as a server (affected). - IsNetworkServer=0: not configured as a server
