The Web server password authentication mechanism used by the products is vulnerable to a MitM and Replay attack. Successful exploitation of this vulnerability will allow unauthorized access of the product’s Web server to view and alter product configuration and diagnostics information.
Rockwell Automation EtherNet/IP products; 1756-ENBT, 1756-EWEB, 1768-ENBT, and 1768-EWEB communication modules; CompactLogix L32E and L35E controllers; 1788-ENBT FLEXLogix adapter; 1794-AENTR FLEX I/O EtherNet/IP adapter; ControlLogix 18 and earlier; CompactLogix 18 and earlier; GuardLogix 18 and earlier; SoftLogix 18 and earlier; CompactLogix controllers 19 and earlier; SoftLogix controllers 19 and earlier; ControlLogix controllers 20 and earlier; GuardLogix controllers 20 and earlier; and MicroLogix 1100 and 1400
Security readout for executives and security teams
This vulnerability affects Rockwell Automation industrial control products with vulnerable web server password authentication. An attacker who can intercept and replay authentication traffic could gain unauthorized access to the device web server and change configuration or diagnostics information. The business risk is high because affected systems may support production or safety-adjacent operations. Exposure is most likely in OT environments running listed Rockwell modules or controllers with their web server reachable from untrusted, shared, or poorly segmented networks. Treat this as urgent for any exposed or production-critical Rockwell environment. Prioritize asset discovery, network restriction, and vendor guidance review before routine maintenance windows. Mitigation focus: Identify affected Rockwell products and firmware generations in asset inventory.; Review Rockwell and CISA advisories for product-specific updates or mitigations.; Restrict web server access to trusted engineering workstations and management networks..

CWE-287: Credential and account abuse lookup
Authentication and credential weaknesses can make valid-account abuse and credential telemetry useful review starting points. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Authentication
Improper Authentication represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
