title: Drive Composer Link Following Local Privilege Escalation Vulnerability
description: Vulnerabilities in the Drive Composer allow a low privileged attacker to create and write to a file anywhere on the file system as SYSTEM with arbitrary content as long as the file does not already exist. The Drive Composer installer file allows a low-privileged user to run a "repair" operation on the product.

workarounds: ABB has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. When a workaround reduces functionality, this is identified below as “Impact of workaround”.
With ABB Automation Builder it is possible to change the version of Drive Composer used so it is not mandatory to update that application immediately. Steps:
1) Install or upgrade Drive Composer pro version to 2.7.1
2) In ABB Automation Builder Options, select External tools.
3) At Drive composer pro-line, select Custom and select the installed Drive Composer pro version 2.7.1 executable typically in C:\Program Files (x86)\DriveWare\Drive Composer pro\2.7
Alternatively, users are able to remove the vulnerable Drive Composer for ABB Automation Builder. This can be done either from ABB Automation Builder Installation manager or from Windows Settings: Apps & features.
