9.1CVE-2021-28500arista networksarista eos+1
EPSS score
0.81%
An issue has recently been discovered in Arista EOS where the incorrect use of EOS's AAA API’s by the OpenConfig and TerminAttr agents could result in unrestricted access to the device for local users with nopassword configuration.
6.8CVE-2021-28508arista networksarista eos+3
EPSS score
0.52%
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 IPsec sensitive data in clear text in CVP to other authorized users, which could cause IPsec traffic to be decrypted or modified by other authorized users on the device.
9.8CVE-2021-28503arista networksarista eos+1
EPSS score
0.73%
The impact of this vulnerability is that Arista's EOS eAPI may skip re-evaluating user credentials when certificate based authentication is used, which allows remote attackers to access the device via eAPI.
9.1CVE-2021-28501arista networksterminattr+1
EPSS score
0.84%
An issue has recently been discovered in Arista EOS where the incorrect use of EOS's AAA API’s by the OpenConfig and TerminAttr agents could result in unrestricted access to the device for local users with nopassword configuration.
9.4CVE-2021-28506arista networkseos+1
EPSS score
1.42%
An issue has recently been discovered in Arista EOS where certain gNOI APIs incorrectly skip authorization and authentication which could potentially allow a factory reset of the device.
7.5CVE-2021-28510arista networkseos+1
EPSS score
1.00%
For certain systems running EOS, a Precision Time Protocol (PTP) packet of a management/signaling message with an invalid Type-Length-Value (TLV) causes the PTP agent to restart. Repeated restarts of the service will make the service unavailable.
7.5CVE-2021-28505arista networkseos+1
EPSS score
0.88%
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.
7.5CVE-2021-28504arista networkseos+1
EPSS score
0.73%
On Arista Strata family products which have “TCAM profile” feature enabled when Port IPv4 access-list has a rule which matches on “vxlan” as protocol then that rule and subsequent rules ( rules declared after it in ACL ) do not match on IP protocol field as expected.
6.5CVE-2021-28511arista networkseos+1
EPSS score
0.58%
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.
6.1CVE-2021-28509arista networksarista eos+3
EPSS score
0.47%
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.
6.5CVE-2021-28496arista networksarista eos+1
EPSS score
0.43%
On systems running Arista EOS and CloudEOS with the affected release version, when using shared secret profiles the password configured for use by BiDirectional Forwarding Detection (BFD) will be leaked when displaying output over eAPI or other JSON outputs to other authenticated users on the device. The affected EOS Versions are: all releases in 4.22.x train, 4.23.9 and below releases in the 4.23.x train, 4.24.7 and below releases in the 4.24.x train, 4.25.4 and below releases in the 4.25.x train, 4.26.1 and below releases in the 4.26.x train
7.1CVE-2021-28507arista networkseos+1
EPSS score
0.67%
An issue has recently been discovered in Arista EOS where, under certain conditions, the service ACL configured for OpenConfig gNOI and OpenConfig RESTCONF might be bypassed, which results in the denied requests being forwarded to the agent.
7.5CVE-2025-54546arista networksdanz monitoring fabric
EPSS score
0.24%
On affected platforms, restricted users could use SSH port forwarding to access host-internal services
5.3CVE-2025-54547arista networksdanz monitoring fabric
EPSS score
0.11%
On affected platforms, if SSH session multiplexing was configured on the client side, SSH sessions (e.g, scp, sftp) multiplexed onto the same channel could perform file-system operations after a configured session timeout expired
5.9CVE-2025-54549arista networksdanz monitoring fabric
EPSS score
0.09%
Cryptographic validation of upgrade images could be circumventing by dropping a specifically crafted file into the upgrade ISO

4.3CVE-2025-54548arista networksdanz monitoring fabric
EPSS score
0.22%
On affected platforms, restricted users could view sensitive portions of the config database via a debug API (e.g., user password hashes)
5.3CVE-2025-2796arista networkseos
EPSS score
0.19%
On affected platforms with hardware IPSec support running Arista EOS with IPsec enabled and anti-replay protection configured, EOS may exhibit unexpected behavior in specific cases. Received duplicate encrypted packets, which should be dropped under normal anti-replay protection, will instead be forwarded due to this vulnerability. Note: this issue does not affect VXLANSec or MACSec encryption functionality.
2.6CVE-2025-2826arista networkseos
EPSS score
0.52%
n affected platforms running Arista EOS, ACL policies may not be enforced. IPv4 ingress ACL, MAC ingress ACL, or IPv6 standard ingress ACL enabled on one or more ethernet or LAG interfaces may result in ACL policies not being enforced for ingress packets. This can cause incoming packets to incorrectly be allowed or denied. The two symptoms of this issue on the affected release and platform are: * Packets which should be permitted may be dropped and, * Packets which should be dropped may be permitted.
7.7CVE-2025-1259arista networkseos
EPSS score
0.35%
On affected platforms running Arista EOS with OpenConfig configured, a gNOI request can be run when it should have been rejected. This issue can result in users retrieving data that should not have been available
