An attacker could exploit the vulnerability by
injecting garbage data or specially crafted data. Depending on the data injected each process might be
affected differently. The process could crash or cause communication issues on the affected node, effectively causing a denial-of-service attack. The attacker could tamper with the data transmitted, causing
the product to store wrong information or act on wrong data or display wrong information.


This issue affects Advant MOD 300 AdvaBuild: from 3.0 through 3.7 SP2.




For an attack to be successful, the attacker must have local access to a node in the system and be able to
start a specially crafted application that disrupts the communication.
An attacker who successfully exploited the vulnerability would be able to manipulate the data in such
way as allowing reads and writes to the controllers or cause Windows processes in 800xA for MOD 300
and AdvaBuild to crash.
Fixes

Solution

ABB recommends changing any user account passwords which are suspected to be known by an unauthorized person. Interactive logon (both local and remote) is recommended to be disabled for service accounts. Please note that the vulnerability can only be exploited by authenticated users, so customers are recommended to ensure that only authorized persons have access to user accounts for the computers where AdvaBuild is used. All the vulnerabilities have been corrected in AdvaBuild version 3.7 SP3 released in April 2021. ABB recommends that customers apply the update at earliest convenience. Users who are unable to install the update should immediately look to implement the “Mitigating factors” listed below as this will restrict or prevent an attacker’s ability to compromise the system.
