Eos Security Vulnerabilities

CVE-2023-3646

On affected platforms running Arista EOS with mirroring to multiple destinations configured, an internal system error may trigger a kernel panic and cause system...

CVE-2023-24548

On affected platforms running Arista EOS with VXLAN configured, malformed or truncated packets received over a VXLAN tunnel and forwarded in hardware can cause egress ports to be unable to forward packets. The device will continue to be susceptible to the issue until remediation is in...

CVE-2023-24510

On the affected platforms running EOS, a malformed DHCP packet might cause the DHCP relay agent to...

CVE-2023-24509

On affected modular platforms running Arista EOS equipped with both redundant supervisor modules and having the redundancy protocol configured with RPR or SSO, an existing unprivileged user can login to the standby supervisor as a root user, leading to a privilege escalation. Valid user...

CVE-2023-24545

On affected platforms running Arista CloudEOS an issue in the Software Forwarding Engine (Sfe) can lead to a potential denial of service attack by sending malformed packets to the switch. This causes a leak of packet buffers and if enough malformed packets are received, the switch may eventually...

CVE-2023-24511

On affected platforms running Arista EOS with SNMP configured, a specially crafted packet can cause a memory leak in the snmpd process. This may result in the snmpd processing being terminated (causing SNMP requests to time out until snmpd is automatically restarted) and potential memory resource.....

CVE-2023-24513

On affected platforms running Arista CloudEOS an issue in the Software Forwarding Engine (Sfe) can lead to a potential denial of service attack by sending malformed packets to the switch. This causes a leak of packet buffers and if enough malformed packets are received, the switch may eventually...

CVE-2023-0451

Econolite EOS versions prior to 3.2.23 lack a password requirement for gaining “READONLY” access to log files and certain database and configuration files. One such file contains tables with MD5 hashes and usernames for all defined users in the control software, including administrators and...

CVE-2023-0452

Econolite EOS versions prior to 3.2.23 use a weak hash algorithm for encrypting privileged user credentials. A configuration file that is accessible without authentication uses MD5 hashes for encrypting credentials, including those of administrators and...

CVE-2021-28510

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...

CVE-2021-28511

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.....

CVE-2021-28508

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...

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.....

CVE-2021-28505

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...

CVE-2021-28504

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...

CVE-2022-26300

EOS v2.1.0 was discovered to contain a heap-buffer-overflow via the function...

CVE-2021-28503

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...

CVE-2021-28500

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...

CVE-2021-28507

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...

CVE-2021-28506

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...

CVE-2021-28496

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...
