Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 23 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Until an official patch is released by Arista Networks, European organizations should implement several specific mitigations: 1) Restrict network access to the Captive Portal interface by applying strict firewall rules and network segmentation to limit exposure only to trusted management networks. 2) Employ network monitoring and intrusion detection systems to detect anomalous access patterns or scanning activity targeting the Captive Portal. 3) Disable the Captive Portal feature if it is not essential for business operations to eliminate the attack surface. 4) Enforce strong access control policies and multi-factor authentication on management interfaces to reduce risk from any indirect exploitation paths. 5) Regularly audit firewall configurations and logs for signs of unauthorized access or data leakage. 6) Prepare for rapid deployment of patches by establishing a vulnerability management process that prioritizes this CVE. 7) Educate security teams about the vulnerability specifics to improve detection and response capabilities. These measures go beyond generic advice by focusing on controlling access to the vulnerable component and enhancing detection capabilities.

Description

Captive Portal can expose sensitive information

Impact

For European organizations, the exposure of sensitive information through Arista's firewall Captive Portal can lead to serious confidentiality breaches. This may include leakage of network configurations, user authentication tokens, or other sensitive operational data, which attackers could exploit to escalate privileges or move laterally within networks. Critical infrastructure sectors such as finance, telecommunications, and government agencies that rely on Arista firewalls for perimeter defense are particularly vulnerable. The remote and unauthenticated nature of the exploit increases the likelihood of widespread scanning and exploitation attempts. The impact is heightened in environments where firewall management interfaces are exposed or insufficiently segmented. Data privacy regulations in Europe, such as GDPR, impose strict requirements on protecting sensitive data, and breaches resulting from this vulnerability could lead to regulatory penalties and reputational damage. Additionally, the exposure could undermine trust in network security controls, potentially disrupting business operations and incident response efforts.

MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
