Vulnerability Data

OctoPrint provides a web interface for controlling consumer 3D printers. In versions up to and including 1.10.3, OctoPrint has a vulnerability that allows an attacker to bypass the login redirect and directly access the rendered HTML of certain frontend pages.…

more

The primary risk lies in potential future modifications to the codebase that might incorrectly rely on the vulnerable internal functions for authentication checks, leading to security vulnerabilities. This issue has been patched in version 1.11.0.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authentication and authorization decisions before allowing access to protected frontend pages, blocking the login-redirect bypass.

prevent

Requires successful identification and authentication of users prior to granting access to OctoPrint's web interface resources.

prevent

Ensures access-control decisions are made by a trusted, non-bypassable mechanism rather than the vulnerable redirect logic.

PR.AA-04 full match
prevents

Protecting, conveying, and verifying identity assertions specifically prevents the spoofing that enables authentication bypass.

PR.AA-03 mostly match
prevents

Requiring authentication of users/services/hardware directly counters spoofing-based bypass when strong methods are used.

PR.AA-02 partial match
prevents

Proofing and binding identities reduces spoofing opportunities during enrollment but does not address runtime authentication implementation flaws.

degrades

Secure authentication control directly mitigates authentication bypass by spoofing.

degrades

Authentication information management directly addresses credential handling that prevents spoofing.

detects

Security testing can detect spoofing vulnerabilities but does not prevent them by itself.

prevents

Access control policy reduces spoofing opportunities but does not prescribe authentication mechanisms.

prevents

Identity management supports unique identities but does not guarantee resistance to spoofing.

prevents

Access rights assignment limits exposure but does not enforce authentication strength.
