CVE-2023-34927

Casdoor through 4.4.0 fails to properly mask the instance-wide built-in certificate private key in /api/get-certs and /api/get-cert endpoints, allowing organization administrators to retrieve it. Attackers can use the exposed private key to forge JWT tokens for any user in any organization, including global administrators.

A vulnerability in Casdoor up to version 4.0.0 affects an unknown function in the file controllers/resource.go of the upload-resource API component. This manipulation leads to missing authentication, and the attack can be launched remotely. The exploit has been publicly disclosed, and the vendor deleted the GitHub issue without explanation and did not respond to email contact.

Development and test API endpoints that mirror production functionality are present in the application. This means they may be accessible in the production environment, posing a risk of unauthorized access.

Casdoor 2.356.0 has a server-side request forgery (SSRF) vulnerability in the Webhook URL Handler component. The attack can be launched remotely without authentication.

In Casdoor version 2.356.0, the dangerouslySetInnerHTML function is vulnerable to cross-site scripting via manipulation of the formCss, formCssMobile, or formSideHtml arguments. The attack can be launched remotely, and the exploit has been publicly released. The vendor did not respond.

A vulnerability was identified in Casdoor 2.356.0 in the OAuth Authorization Request Handler. Manipulation of the redirect_uri argument leads to an open redirect. The attack can be performed remotely and the exploit is publicly available.

In Casdoor version 2.26.0 and earlier, a vulnerability in the permission verification module and organization/application editing interface allows remote authenticated administrators of any organization to bypass the system's permission verification mechanism by directly concatenating URLs after login. The issue is fixed in version 2.63.0.
