An attacker could exploit this vulnerability by sending a crafted request to the API of an affected system. A successful exploit could allow the attacker to execute commands with the privileges of the netadmin role.\r\n\r\nNote: Cisco Catalyst SD-WAN Manager releases 20.18 and later are not affected by this vulnerability.\r\n\r\nCisco has released software updates that address this vulnerability.

An attacker could exploit this vulnerability by sending a request to the REST API of the affected system. A successful exploit could allow the attacker to gain root privileges on the underlying operating system.\r\n\r\nCisco has released software updates that address this vulnerability.

If internet access to the system is required, restrict system access to only known, trusted hosts on ports/protocols that are included in the user guides.\r\nProtect Cisco Catalyst SD-WAN Control Components behind a filtering device such as a firewall, and filter traffic to and from the systems while allowing only known, trusted hosts to send traffic to the systems. Using a two-layer firewall can provide flexibility in network planning so that end users do not connect directly to the outer DMZ. See the Deployment sections of the User Guides for Cisco Catalyst SD-WAN software [\"https://www.cisco.com/c/en/us/td/docs/solutions/CVD/SDWAN/cisco-sdwan-design-guide.html#DeploymentPlanning\"].\r\nRegularly monitor log traffic for any unexpected traffic to and from systems. Logging should be sent to an external server, if possible, and kept for a long enough duration so that post-event investigations can be performed with sufficient log data.\r\nDisable HTTP for the Cisco Catalyst SD-WAN Manager web UI administrator portal.\r\nDisable any network services that are not required, including HTTP and FTP. For more information about specific service functionality, see the Cisco Catalyst SD-WAN user guides.\r\nUpgrade the system to the latest version of Cisco Catalyst SD-WAN Software.\r\nChange the default administrator password to a more secure variant. Restrict access to the administrator account by creating user accounts based on necessary access requirements. In addition, create operator accounts for all administrators.\r\nUse SSL/TLS, obtain an SSL certificate from a certificate authority (CA), or create a self-signed certificate.\r\n\r\nFor more information, review the Cisco Catalyst SD-WAN Hardening Guide [\"https://sec.cloudapps.cisco.com/security/center/resources/Cisco-Catalyst-SD-WAN-HardeningGuide\"].",

        "text": "De kwetsbaarheden bevinden zich in de peering authenticatiemechanismen van de Cisco Catalyst SD-WAN Controller en Manager producten. Deze kwetsbaarheden stellen een niet-geauthenticeerde externe aanvaller in staat om het authenticatieproces te omzeilen, waardoor administratieve privileges op de getroffen systemen kunnen worden verkregen. Daarnaast kunnen aanvallers root-level privileges verkrijgen, wat kan leiden tot ongeautoriseerde toegang tot gevoelige informatie en de mogelijkheid om willekeurige bestanden te overschrijven, wat kan resulteren in verdere exploitatie of systeeminstabiliteit.\n\nDe meest ernstige kwetsbaarheid, met kenmerk CVE-2026-20127, kan door een ongeauthenticeerde kwaadwillende worden misbruikt om op afstand willekeurige code uit te voeren met hoge administratieve rechten. Cisco geeft aan dat actief misbruik van deze kwetsbaarheid bekend is.\n\nNa misbruik van deze kwetsbaarheid zou de kwaadwillende de kwetsbaarheid met kenmerk CVE-2022-20775 gebruiken om de rechten te escaleren tot root. Dit doet de actor door het systeem te downgraden naar een versie waarin CVE-2022-20775 niet verholpen is, de rechten middels deze kwetsbaarheid te verhogen naar root en vervolgens het systeem weer terug te zetten in de oorspronkelijke versie.\n\nEr is publieke Proof-of-Concept-code (PoC) verschenen die de kwetsbaarheid met kenmerk CVE-2026-20127 aantoont en mogelijk misbruikt. De kans op grootschalig misbruik neemt hierdoor toe en het NCSC verwacht een significante toename in scan- en misbruikverkeer. Het NCSC adviseert met klem de update zo spoedig mogelijk te installeren.\n\nOok van de kwetsbaarheden met kenmerk CVE-2026-20122 en CVE-2026-20128 meldt Cisco berichten te ontvangen dat deze actief worden misbruikt. Voor deze kwetsbaarheden is (nog) geen publieke Proof-of-Concept-code of exploit beschikbaar.",
