Mapping is CWE-to-CAPEC per MITRE CAPEC 3.9.
The Schneider Electric Quantum Ethernet Module on the NOE 771 device contains a vulnerability where the ComputePassword function generates the password for the fwupgrade account using the MAC address. This allows remote attackers to obtain access via ARP requests or Neighbor Solicitation messages, leading to full system compromise.
BSID: BS-2011-GLOBAL-089624-C • Model: Qwen/Qwen2.5-72B-Instruct-AWQ • Confidence: HIGH

The ComputePassword function in the Schneider Electric Quantum Ethernet Module on the NOE 771 device (aka the Quantum 140NOE771* module) generates the password for the fwupgrade account by performing a calculation on the MAC address, which makes it easier for remote attackers to obtain access via a (1) ARP request message or (2) Neighbor Solicitation message.
Source: NIST NVD / MITRE CVE Database
Remote attackers can exploit the vulnerability by sending an ARP request or Neighbor Solicitation message to the device. The response will contain the MAC address, which can be used to calculate the password for the fwupgrade account. Once the password is obtained, the attacker gains full control over the device.

Implement network segmentation to isolate the affected devices from untrusted networks. Use firewalls to block unauthorized access to the device's management interfaces.
No reliable network detection signature exists for this vulnerability class — apply the compensating controls above and the vendor patch. SAGE only publishes a network rule when a concrete on-the-wire signature can be grounded in the advisory.
This CVE violates CIP-007-R2 because it allows unauthorized access to the device, which could lead to the compromise of critical cyber assets.
This CVE maps to SR 7.6 because it involves a vulnerability that can be exploited to gain unauthorized access to the device, compromising the security of the industrial control system.
Virtual patch generated by CITED Relevance SAGE. Validate in isolated environment before production deployment. Compensating control only - does not replace vendor patch.
