CVSS: 6.1EPSS: 0%CPEs: 91EXPL: 1CVE-2021-28509 – TerminAttr streams MACsec sensitive data in clear text to other authorized users in CVP
https://notcve.org/view.php?id=CVE-2021-28509
This advisory documents the impact of an internally found vulnerability in Arista EOS state streaming telemetry agent TerminAttr and OpenConfig transport protocols. The impact of this vulnerability is that, in certain conditions, TerminAttr might leak MACsec sensitive data in clear text in CVP to other authorized users, which could cause MACsec traffic to be decrypted or modified by other authorized users on the device. Este aviso documenta el impacto de una vulnerabilidad encontrada internamente en los protocolos de transporte TerminAttr y OpenConfig del agente de telemetría de transmisión de estados de Arista EOS. El impacto de esta vulnerabilidad es que, en determinadas condiciones, TerminAttr podría filtrar datos confidenciales MACsec en texto sin cifrar en CVP a otros usuarios autorizados, lo que podría causar que el tráfico MACsec sea descifrado o modificado por otros usuarios autorizados en el dispositivo • https://www.arista.com/en/support/advisories-notices/security-advisories/15484-security-advisory-0077 • CWE-255: Credentials Management Errors CWE-319: Cleartext Transmission of Sensitive Information •
