CVE-2026-8173: CWE-209 Generation of Error Message Containing Sensitive Information in Murrelektronik Xelity 4TX M GE
CVE-2026-8173 is a medium severity vulnerability in the Murrelektronik Xelity 4TX M GE switch version 2.1.0. The web GUI improperly generates error messages that expose MAC addresses logged from the device's MAC address table. An unauthenticated attacker with network access to the web interface can retrieve these MAC addresses via browser developer tools by exploiting the 'Copy learned MAC Addresses' function.
AI Analysis
Technical Summary
The vulnerability arises from improper error message generation in the web GUI of Murrelektronik Xelity 4TX M GE switches (version 2.1.0). When an authenticated administrator uses the 'Copy learned MAC Addresses' function, MAC addresses are logged. Due to CWE-209 (generation of error message containing sensitive information), an unauthenticated attacker with network access to the web interface can access these logged MAC addresses through browser developer tools, potentially leaking sensitive network information.
Potential Impact
An unauthenticated attacker with network access to the device's web interface can obtain MAC addresses from the device's MAC address table. This information disclosure could aid in network reconnaissance but does not directly allow system compromise or denial of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict network access to the device's web interface to trusted administrators only.
