CVE-2026-20209ciscocatalyst_sd-wan_manager+1
EPSS score0.19%
A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an authenticated, remote attacker with read-only permissions to elevate their privileges from low to high and perform actions as a high-privileged user.
This vulnerability exists because sensitive session information is recorded in audit logs. An attacker could exploit this vulnerability by elevating their read-only permissions in Cisco Catalyst SD-WAN Manager to those of a high-privileged user. A successful exploit could allow the attacker to perform actions as a high-privileged user.CVE-2026-20262ciscocatalyst_sd-wan_manager+1KEVEPSS score28.17%
A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an authenticated, remote attacker to create a file or overwrite any file on the filesystem of an affected system.
This vulnerability exists because the affected software does not properly validate user-supplied input during a file upload process. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected API endpoint of the affected system. A successful exploit could allow the attacker to create or overwrite any file on the underlying operating system. This file could later be used to elevate to root. To exploit this vulnerability, the attacker must have valid credentials with at least a lower-privileged, single-task user account.CVE-2026-20128ciscocatalyst_sd-wan_manager+1KEVEPSS score7.22%
A vulnerability in the Data Collection Agent (DCA) feature of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to gain DCA user privileges on an affected system.
This vulnerability is due to the presence of a credential file for the DCA user on an affected system. An attacker could exploit this vulnerability by sending a crafted HTTP request and reading the file that contains the DCA password from that affected system. A successful exploit could allow the attacker to access another affected system and gain DCA user privileges.
Note: Cisco Catalyst SD-WAN Manager releases 20.18 and later are not affected by this vulnerability.CVE-2026-20133ciscocatalyst_sd-wan_manager+1KEVEPSS score32.43%
A vulnerability in Cisco Catalyst SD-WAN Software could allow an unauthenticated, remote attacker to view sensitive information on an affected system.
This vulnerability is due to insufficient file system restrictions. An authenticated attacker with netadmin privileges could exploit this vulnerability by accessing the vshell of an affected system. A successful exploit could allow the attacker to read sensitive information on the underlying operating system.CVE-2026-20182ciscocatalyst_sd-wan_manager+4KEVEPSS score91.82%
May 2026: This security advisory provides the details and fix information for a vulnerability that was discovered and fixed after the was disclosed in February 2026. This new advisory is for a new vulnerability in the control connection handshaking. The section of this advisory includes Show Control Connections guidance to help with system checks.
A vulnerability in the peering authentication in Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative privileges on an affected system.
This vulnerability exists because the peering authentication mechanism in an affected system is not working properly. An attacker could exploit this vulnerability by sending crafted requests to the affected system. A successful exploit could allow the attacker to log in to an affected Cisco Catalyst SD-WAN Controller as an internal, high-privileged, non-root user account. Using this account, the attacker could access NETCONF, which would then allow the attacker to manipulate network configuration for the SD-WAN fabric.CVE-2026-76504ciscocatalyst_sd-wan_manager+1KEVEPSS score1.82%
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.
This 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.CVE-2023-20262ciscocatalyst_sd-wan_manager+4EPSS score1.00%
A vulnerability in the SSH service of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to cause a process crash, resulting in a DoS condition for SSH access only. This vulnerability does not prevent the system from continuing to function, and web UI access is not affected.
This vulnerability is due to insufficient resource management when an affected system is in an error condition. An attacker could exploit this vulnerability by sending malicious traffic to the affected system. A successful exploit could allow the attacker to cause the SSH process to crash and restart, resulting in a DoS condition for the SSH service.CVE-2023-20214ciscocatalyst_sd-wan_manager+2EPSS score0.92%
A vulnerability in the request authentication validation for the REST API of Cisco SD-WAN vManage software could allow an unauthenticated, remote attacker to gain read permissions or limited write permissions to the configuration of an affected Cisco SD-WAN vManage instance.
This vulnerability is due to insufficient request validation when using the REST API feature. An attacker could exploit this vulnerability by sending a crafted API request to an affected vManage instance. A successful exploit could allow the attacker to retrieve information from and send information to the configuration of the affected Cisco vManage instance. This vulnerability only affects the REST API and does not affect the web-based management interface or the CLI.CVE-2023-20098ciscocatalyst_sd-wan_manager+2EPSS score0.51%
A vulnerability in the CLI of Cisco SDWAN vManage Software could allow an authenticated, local attacker to delete arbitrary files.
This vulnerability is due to improper filtering of directory traversal character sequences within system commands. An attacker with administrative privileges could exploit this vulnerability by running a system command containing directory traversal character sequences to target an arbitrary file. A successful exploit could allow the attacker to delete arbitrary files from the system, including files owned by root.CVE-2023-20253ciscocatalyst_sd-wan_manager+2EPSS score0.17%
A vulnerability in the command line interface (cli) management interface of Cisco SD-WAN vManage could allow an authenticated, local attacker to bypass authorization and allow the attacker to roll back the configuration on vManage controllers and edge router device.
This vulnerability is due to improper access control in the cli-management interface of an affected system. An attacker with low-privilege (read only) access to the cli could exploit this vulnerability by sending a request to roll back the configuration on for other controller and devices managed by an affected system. A successful exploit could allow the attacker to to roll back the configuration on for other controller and devices managed by an affected system.CVE-2023-20261ciscocatalyst_sd-wan_manager+1EPSS score0.71%
A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager could allow an authenticated, remote attacker to retrieve arbitrary files from an affected system.
This vulnerability is due to improper validation of parameters that are sent to the web UI. An attacker could exploit this vulnerability by logging in to Cisco Catalyst SD-WAN Manager and issuing crafted requests using the web UI. A successful exploit could allow the attacker to obtain arbitrary files from the underlying Linux file system of an affected system. To exploit this vulnerability, the attacker must be an authenticated user.CVE-2023-20252ciscocatalyst_sd-wan_manager+1EPSS score1.09%
A vulnerability in the Security Assertion Markup Language (SAML) APIs of Cisco Catalyst SD-WAN Manager Software could allow an unauthenticated, remote attacker to gain unauthorized access to the application as an arbitrary user.
This vulnerability is due to improper authentication checks for SAML APIs. An attacker could exploit this vulnerability by sending requests directly to the SAML API. A successful exploit could allow the attacker to generate an authorization token sufficient to gain access to the application.
