        "text": "A vulnerability in the API session-based authentication management of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to access an affected system with privileges of the admin user.\r\n\r\nThis vulnerability is due to improper handling of URI encoding in an HTTP request, which allows the request to bypass an authentication rule that is intended to restrict access to a specific API endpoint. An attacker could exploit this vulnerability by sending a crafted HTTP request to the API of the affected system. A successful exploit could allow the attacker to bypass authentication and gain access to the API as the admin user.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\n",

In some instances, these indicators of compromise (IOCs) may occur during standard operations. Therefore, they must be assessed against normal network posture to identify and avoid false positives.\r\n\r\nImportant: These IOC examples show the use of %6a as the URI encoded character j in the request. This is only an example, and the vulnerability will allow any one character that is encoded in the request to be used to exploit this.\r\n\r\nCustomers are encouraged to audit the serviceproxy-access.log file, located at /var/log/nms/containers/service-proxy/serviceproxy-access.log, for entries that are related to j_security_check from unknown or unauthorized IP addresses, as shown in the following example:\r\n\r\n\r\n[2026-09-29T23:11:13.948-05:00] \"POST /%6a_security_check HTTP/1.1\" 200 - 48 0 4 - \"10.10.10.47,192.168.1.174\" \"Mozilla/5.0\" \"92980fc6-bb3c-4b67-8a6d-af5ceb236d4c\" \"vmanage-9999.example.com\" \"127.0.0.1:8080\"\r\n\r\nCustomers are encouraged to audit the vmanage-server.log file, located at /var/log/nms/vmanage-server.log, for entries that are related to j_security_check from unknown or unauthorized IP addresses, specifically being called for users that include names starting with viptela-reserved-, as shown in the following example:\r\n\r\n\r\n29-Sep-2026 23:11:13,952 CDT [] [vManage-new] [UserUtils] (default task-127462) |default| Request Stored in Map is (/%6a_security_check) for user (viptela-reserved-..)\r\n\r\nFor help determining if Cisco Catalyst SD-WAN Manager has been compromised, customers may open a case with the Cisco Technical Assistance Center (TAC).

Before opening a new TAC case, customers are encouraged to use the request admin-tech command from the Cisco Catalyst SD-WAN Manager (vManage) in the SD-WAN deployment so that the admin-tech file can be provided to the Cisco TAC for review.\r\n\r\nThe viptela-reserved system service accounts are documented in the Authentication, Authorization, and Accounting [\"https://www.cisco.com/c/en/us/td/docs/routers/sdwan/17-x/systems-interfaces/systems-interfaces-guide-17-x/authentication.html?bookSearch=true#aaa-using-config-group\"] section of the Cisco Catalyst SD-WAN Systems and Interfaces Configuration Guide.",

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 web 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\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\nWhen using SSL/TLS, obtain an SSL certificate from a certificate authority (CA).\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\"].",
