Evidence used

  • CISA confirms exploitation in the wild.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 14.03% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Cisco Identity Services Engine and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  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: Within 3 daysRemediation target: Within 90 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.

CISA KEV mirrored by ENISA

A vulnerability in an API of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to bypass authentication. This vulnerability is due to insufficient authentication control on an API endpoint. An attacker could exploit this vulnerability by sending a crafted request to an affected API endpoint. A successful exploit could allow the attacker to gain unauthorized access to the affected device by bypassing the web-based management interface.

01

What, why and how

Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) contain an incorrect use of privileged APIs vulnerability that could allow an unauthenticated, remote attacker to gain unauthorized access to the affected device by bypassing the web-based management interface.

What

Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) contain an incorrect use of privileged APIs vulnerability that could allow an unauthenticated, remote attacker to gain unauthorized access to the affected device by bypassing the web-based management interface.

Why

The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Cisco Identity Services Engine Incorrect Use of Privileged APIs Vulnerability

Official advisory ↗
NCSC-NL · Dutch · NCSC-2026-0382Kwetsbaarheden verholpen in Cisco Identity Services Engine (ISE)

De kwetsbaarheden betreffen verschillende beveiligingsproblemen in Cisco ISE en ISE-PIC, waaronder mogelijkheden voor niet-geauthenticeerde en laaggeprivilegieerde kwaadwillenden om via netwerktoegang ongeautoriseerde acties uit te voeren. De kwetsbaarheden hebben CVSS-scores variërend van middel tot kritiek. Van de in totaal 21 kwetsbaarheden zijn 13 als kritiek aangemerkt. Op basis van de door Cisco gepubliceerde CVSS-scores kunnen vier kwetsbaarheden zonder authenticatie op afstand worden misbruikt. Succesvol misbruik kan onder meer leiden tot het omzeilen van authenticatie- en autorisatiecontroles, het verkrijgen en wijzigen van gevoelige configuratie- en identiteitsgegevens, het uitvoeren van willekeurige code of commando's met rootrechten, SQL-injectie, het uitlezen van bestanden en het verstoren van de beschikbaarheid van getroffen systemen. Sommige kwetsbaarheden vereisen voorafgaande administratieve toegangsrechten of een specifieke configuratie, terwijl andere volledig op afstand en zonder authenticatie kunnen worden misbruikt. Van de 13 kwetsbaarheden die als kritiek zijn aangemerkt, hebben meerdere een CVSS-score van 9,8 of hoger. Vier kwetsbaarheden, CVE-2026-20130, CVE-2026-20192, CVE-2026-76423 en CVE-2026-76460, hebben een CVSS-score van 10,0. De kwetsbaarheid met kenmerk CVE-2026-76423 betreft een kwetsbaarheid in de REST API waarmee een niet-geauthenticeerde kwaadwillende administratieve toegang kan verkrijgen tot Cisco ISE en ISE-PIC. De kwetsbaarheid met kenmerk CVE-2026-76460 betreft een authenticatieomzeiling in een API van Cisco ISE en ISE-PIC waarmee een niet-geauthenticeerde kwaadwillende toegang tot het getroffen systeem kan verkrijgen. Cisco meldt dat deze kwetsbaarheid actief wordt misbruikt. Na succesvolle exploitatie kunnen kwaadwillenden volgens Cisco commando's met rootrechten uitvoeren. De kwetsbaarheden met kenmerk CVE-2026-20130 en CVE-2026-20192 betreffen door Cisco gegroepeerde kwetsbaarheden op het gebied van respectievelijk onvoldoende neutralisatie van invoer en onjuiste toegangscontrole. Cisco heeft voor deze hardening-release meerdere onderliggende kwetsbaarheden per CWE-klasse onder één CVE-ID samengebracht. De CVSS-score vertegenwoordigt daarbij de hoogst scorende onderliggende kwetsbaarheid. Het NCSC adviseert om de beveiligingsupdates voor de kritieke kwetsbaarheden met voorrang toe te passen.

Restrict access to management interfaces through access control lists (ACL), network segmentation, and trusted administration networks where feasible. If compromise is suspected, re-image affected nodes and restore from known-good backups, as attackers may obtain elevated privileges and remove evidence of exploitation.

Affected product Affected releases Fixed releases Cisco Identity Services Engine (ISE) or ISE-PIC releases prior to 3.0 Migrate to a fixed release Cisco Identity Services Engine (ISE) or ISE-PIC release 3.1 3.1 Patch 12 Cisco Identity Services Engine (ISE) or ISE-PIC release 3.2 3.2 Patch 11 Cisco Identity Services Engine (ISE) or ISE-PIC release 3.3 3.3 Patch 12 Cisco Identity Services Engine (ISE) or ISE-PIC release 3.4 3.4 Patch 7 Cisco Identity Services Engine (ISE) or ISE-PIC release 3.5 3.5 Patch 4 The Cyber Centre also recommends organizations to: Apply vendor-provided security updates immediately. Cisco has released fixes for all three vulnerabilities. Prioritize remediation of CVE-2026-76460 due to confirmed in-the-wild exploitation. Review access logs for indicators of compromise (IoC), particularly suspicious usernames and unexpected API activity. Restrict access to management interfaces through access control lists (ACL), network segmentation, and trusted administration networks where feasible. If compromise is suspected, re-image affected nodes and restore from known-good backups, as attackers may obtain elevated privileges and remove evidence of exploitation. Monitor firewall, network, and authentication logs for anomalous activity associated with affected systems. Note: Organizations operating Common Criteria Footnote 10 evaluated configurations should review Cisco's advisory and apply the recommended updates in accordance with their change management and certification requirements.
