V7.4 (All versions < V7.4 SP1 Update 23), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 17), SIMATIC WinCC V8.0 (All versions < V8.0 Update 5). The affected products do not properly handle certain requests to their web application, which may lead to the leak of privileged information. This could allow an unauthenticated remote attacker to retrieve information such as users and passwords.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces authorizations so that PII is not reachable by unauthorized actors.

AC-21 Information Sharing good match

Requires explicit verification that a recipient's authorizations match the sensitivity of shared PII.

AC-6 Least Privilege good match

Limits granted rights to the minimum needed, reducing the set of actors who can reach private data.

PT-2 Authority to Process Personally Identifiable Information good match

Documents the legal or consent basis required before any processing of PII occurs.

PT-4 Consent good match

Implements consent mechanisms that directly block access absent the individual's permission.

SC-28 Protection of Information at Rest good match

Encrypts or otherwise protects stored PII against unauthorized retrieval.

RC.CO-04 partial match
degrades

CWE-359 does not impair RC.CO-04's ability to issue approved public recovery updates, yet any resulting PII exposure can partially undermine the outcome's overall efficacy and trust.

A.8.11 Data masking mostly match
prevents

Masking or anonymizing personal identifiers limits the amount of private personal information that can be disclosed through application outputs or logs.

A.8.12 Data leakage prevention mostly match
prevents

Monitoring and quarantining outbound messages that contain personal or private data directly reduces the chance that such information will be disclosed to unauthorized recipients.

A.8.33 Test information mostly match
prevents

The explicit prohibition on copying personally identifiable information into development and test environments directly lowers the exposure of private personal data to staff or processes that should not see it.

A.5.14 Information transfer partial match
mitigates

Labeling, chain-of-custody, and access-control requirements limit the exposure of private personal information during any transfer method.

A.5.34 Privacy and protection of PII partial match
prevents

Mandating privacy procedures and a designated privacy officer helps ensure that private personal information is not disclosed without proper authorization or necessity.

A.6.6 Confidentiality or non-disclosure agreements partial match
mitigates

The agreements impose enforceable restrictions on the handling of private personal information, thereby decreasing the risk that such data will be exposed to unauthorized parties.
