Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.64% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Cisco Cisco Enterprise NFV Infrastructure Software and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

EUVD-2026-53466

No EUVD known-exploited evidence

A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with Admin privileges to execute arbitrary commands on the underlying operating system of an affected system and elevate privileges to root.  This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted inputs to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.  Cisco has assigned this vulnerability a SIR of High rather than Medium as the score indicates because additional security implications could occur when the attacker becomes root.

01

What, why and how

A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with Admin privileges to execute arbitrary commands on the underlying operating system of an affected system and elevate privileges to root.  This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted inputs to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.  Cisco has assigned this vulnerability a SIR of High rather than Medium as the score indicates because additional security implications could occur when the attacker becomes root.

A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.  Cisco has assigned this vulnerability a SIR of High rather than Medium as the score indicates because additional security implications could occur when the attacker becomes root.

Why

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as expression or command delimiters when they are sent to a downstream component.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Neutralization of Expression/Command Delimiters → execute code or commands in the affected security context
Attack surface
Network
Privileges required
High: elevated access is required
User interaction

Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-146 ↗

CWE-146: Improper Neutralization of Expression/Command Delimiters. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as expression or command delimiters when they are sent to a downstream component.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.ANoneAvailability impact: No direct loss is represented by this metric.
Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.

CSIRT Italia · Italian · risolte-vulnerabilita-in-prodotti-cisco-29Risolte vulnerabilità in prodotti Cisco

Cisco ha rilasciato aggiornamenti di sicurezza che risolvono molteplici vulnerabilità, tra cui 5 con gravità "critica" e 11 con gravità “alta”, riguardanti vari prodotti. In particolare si evidenziano la CVE-2026-20316 che risulta attivamente sfruttata in rete e la CVE-2026-20200 , per la quale è disponibile un Proof of Concept (PoC). Di seguito i dettagli: CVE-2026-20316 , di tipo "Static Credential" e con score CVSS v3.1 pari a 5.3, interessa l'interfaccia web di Cisco Secure Firewall Management Center (FMC): la presenza di credenziali statiche associate a un account a basso privilegio consente a un attaccante remoto non autenticato di utilizzare tale account per effettuare il log-in sul sistema e ottenere l'accesso a dati sensibili presenti sul dispositivo; CVE-2026-20200 , di tipo "Argument Injection" e con score CVSS v3.1 pari a 8.8, interessa l'interfaccia di gestione web di Cisco Integrated Management Controller (IMC) ed è dovuta ad una non corretta gestione dell'input fornito dall'utente: un attaccante remoto autenticato con bassi privilegi potrebbe sfruttare tale vulnerabilità, tramite l'invio di input appositamente predisposti all'interfaccia di gestione web, per eseguire comandi arbitrari, con privilegi elevati, sul sistema operativo sottostante.
