Description
Multiple Broken Authentication security issues exist in the affected product. The security issues are due to missing authentication checks on critical functions. These could result in potential denial-of-service, admin account takeover, or NAT rule modifications. Devices would no longer be able to communicate through NATR as a result of denial-of-service or NAT rule modifications. NAT rule modification could also result in device communication to incorrect endpoints. Admin account takeover could allow modification of configuration and require physical access to restore.

- Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
- Authentication (AT): None (N) - No authentication is required to exploit the vulnerability.
- Privileges Required (PR): None (N) - No special privileges are needed.
- User Interaction (UI): None (N) - No user interaction is required.
- Confidentiality (VC): High (H) - There is a high impact on confidentiality.
- Integrity (VI): High (H) - There is a high impact on integrity.
- Availability (VA): High (H) - There is a high impact on availability.
- Scope (SC): Not Changed (N) - The scope of the vulnerability does not change.
- Scope Integrity (SI): Not Changed (N) - The scope integrity does not change.
- Scope Availability (SA): High (H) - There is a high impact on scope availability.
2. Potential Attack Vectors and Exploitation Methods
The vulnerability can be exploited through the following attack vectors:
- Denial-of-Service (DoS): An attacker could exploit the missing authentication checks to cause a DoS condition, rendering the device unable to communicate through NATR.
- Admin Account Takeover: By exploiting the vulnerability, an attacker could gain control of the admin account, allowing them to modify configurations and potentially lock out legitimate users.
- NAT Rule Modifications: An attacker could alter NAT rules, leading to device communication with incorrect endpoints, which could result in data leakage or unauthorized access.
3. Affected Systems and Software Versions
The affected product is Rockwell Automation Comms - 1783-NATR, specifically versions 1.006 and prior. Organizations using these versions are at risk and should prioritize updating or applying mitigations.
4. Recommended Mitigation Strategies
To mitigate the risks associated with this vulnerability, the following strategies are recommended:
- Update Software: Upgrade to a patched version of the Comms - 1783-NATR product as soon as it becomes available.
- Network Segmentation: Implement network segmentation to isolate critical systems and reduce the attack surface.
- Access Controls: Enforce strict access controls and monitor for unauthorized access attempts.
- Monitoring and Logging: Enable comprehensive logging and monitoring to detect and respond to suspicious activities promptly.
- Intrusion Detection Systems (IDS): Deploy IDS to identify and alert on potential exploitation attempts.
- Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address potential weaknesses.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to European organizations, particularly those in critical infrastructure sectors such as manufacturing, energy, and utilities, where Rockwell Automation products are commonly used.
