CVE-2024-6326

An exposure of sensitive information vulnerability exists in the Rockwell Automation FactoryTalk® System Service. A malicious user could exploit this vulnerability by starting a back-up or restore process, which temporarily exposes private keys, passwords, pre-shared keys, and database folders when they are temporarily copied to an interim folder. This vulnerability is due to the lack of explicit permissions set on the backup folder. If private keys are obtained by a malicious user, they could impersonate resources on the secured network.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Affected Software

Potential Mitigations

• Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
• Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
