Summary
Cisco heeft 21 kwetsbaarheden verholpen in Cisco Identity Services Engine (ISE) en Cisco ISE Passive Identity Connector (ISE-PIC).
Details
Interpretaties
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.
Oplossingen
Cisco heeft updates uitgebracht voor Cisco Identity Services Engine (ISE) en Cisco ISE Passive Identity Connector (ISE-PIC) om de kwetsbaarheden te verhelpen.
Cisco heeft voor de kwetsbaarheid met kenmerk CVE-2026-76460 een IoC opgenomen in de betreffende advisory. Omdat een kwaadwillende na succesvolle exploitatie rootrechten kan verkrijgen en sporen van misbruik kan verwijderen of verbergen, adviseert Cisco ook externe netwerk- en firewalllogs te controleren. Wanneer aanwijzingen voor misbruik worden aangetroffen, adviseert Cisco om de getroffen nodes opnieuw te installeren en indien nodig de configuratie vanuit een back-up te herstellen. Zie bijgevoegde advisory voor meer informatie.
Voor de kwetsbaarheden met kenmerk CVE-2026-20130 en CVE-2026-20192 heeft Cisco daarnaast software-hardeningupdates uitgebracht. Raadpleeg de bijgevoegde advisories voor meer informatie.
