An issue was discovered in SolarWinds N-Central 12.3.0.670. The AdvancedScripts HTTP endpoint allows Relative Path Traversal by an authenticated user of the N-Central Administration Console (NAC), leading to execution of OS commands as root.
An issue was discovered in SolarWinds N-Central 12.3.0.670. The sudo configuration has incorrect access control because the nable web user account is effectively able to run arbitrary OS commands as root (i.e., the use of root privileges is not limited to specific programs listed in the sudoers file).
An issue was discovered in SolarWinds N-Central 12.3.0.670. The SSH component does not restrict the Communication Channel to Intended Endpoints. An attacker can leverage an SSH feature (port forwarding with a temporary key pair) to access network services on the 127.0.0.1 interface, even though this feature was only intended for user-to-agent communication.
SolarWinds Database Performance Analyzer (DPA) 11.1.468 and 12.0.3074 have several persistent XSS vulnerabilities, related to logViewer.iwc, centralManage.cen, userAdministration.iwc, database.iwc, alertManagement.iwc, eventAnnotations.iwc, and central.cen.
SolarWinds N-central through 2020.1 allows session hijacking and requires user interaction or physical access. The N-Central JSESSIONID cookie attribute is not checked against multiple sources such as sourceip, MFA claim, etc. as long as the victim stays logged in within N-Central. To take advantage of this, cookie could be stolen and the JSESSIONID can be captured. On its own this is not a surprising result; low security tools allow the cookie to roam from machine to machine. The JSESSION cookie can then be used on the attackers’ workstation by browsing to the victim’s NCentral server URL and replacing the JSESSIONID attribute value by the captured value. Expected behavior would be to check this against a second source and enforce at least a reauthentication or multi factor request as N-Central is a highly privileged service.
SolarWinds N-Central version 12.3 GA and lower does not set the JSESSIONID attribute to HTTPOnly. This makes it possible to influence the cookie with javascript. An attacker could send the user to a prepared webpage or by influencing JavaScript to the extract the JESSIONID. This could then be forwarded to the attacker.
Stored XSS (Cross-Site Scripting) exists in the SolarWinds Orion Platform before before 2020.2.1 on multiple forms and pages. This vulnerability may lead to the Information Disclosure and Escalation of Privileges (takeover of administrator account).
