This advisory documents the impact of an internally found vulnerability in Arista EOS for security ACL bypass. The impact of this vulnerability is that the security ACL drop rule might be bypassed if a NAT ACL rule filter with permit action matches the packet flow. This could allow a host with an IP address in a range that matches the range allowed by a NAT ACL and a range denied by a Security ACL to be forwarded incorrectly as it should have been denied by the Security ACL. This can enable an ACL bypass. Este aviso documenta el impacto de una vulnerabilidad encontrada internamente en Arista EOS para omitir las ACL de seguridad. • https://www.arista.com/en/support/advisories-notices/security-advisory/15862-security-advisory-0078 • CWE-284: Improper Access Control •
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 •

On affected Arista EOS platforms, if a VXLAN match rule exists in an IPv4 access-list that is applied to the ingress of an L2 or an L3 port/SVI, the VXLAN rule and subsequent ACL rules in that access list will ignore the specified IP protocol. En las plataformas Arista EOS afectadas, si se presenta una regla de coincidencia VXLAN en una lista de acceso IPv4 que es aplicada a la entrada de un puerto/SVI L2 o L3, la regla VXLAN y las reglas ACL posteriores en esa lista de acceso ignorarán el protocolo IP especificado • https://www.arista.com/en/support/advisories-notices/security-advisories/15267-security-advisory-0073 • CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
