Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Quarkus framework has a security flaw in the `quarkus-security-webauthn` module. π **Consequences**: Default REST endpoints remain enabled, leading to potential **arbitrary user login** attacks.β¦
π‘οΈ **Root Cause**: **CWE-288** (Authentication Bypass). The specific flaw is the **default REST endpoint not being disabled** in the WebAuthn security module. β οΈ Misconfiguration by default!
Q3Who is affected? (Versions/Components)
π₯ **Affected**: Applications using the **Quarkus** framework, specifically those utilizing the `quarkus-security-webauthn` module. π³ Cloud-native Java apps on Linux containers are at risk.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Hackers can bypass authentication mechanisms. π They can achieve **arbitrary user login**, gaining unauthorized access to user accounts and sensitive data without valid credentials.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **LOW**. π CVSS Vector shows `AV:N` (Network), `AC:L` (Low Complexity), `PR:N` (No Privileges Required), `UI:N` (No User Interaction). Easy to exploit remotely!
Q6Is there a public Exp? (PoC/Wild Exploitation)
π¦ **Public Exploit**: **No**. The `pocs` field is empty in the provided data. π« No public Proof-of-Concept or wild exploitation code is currently available based on this record.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Quarkus apps using the `quarkus-security-webauthn` module. π Verify if the default WebAuthn REST endpoints are exposed and **not disabled** in the configuration.
π **No Patch Workaround**: Manually **disable the default REST endpoints** in the `quarkus-security-webauthn` module configuration. π Restrict network access to these endpoints if possible.
Q10Is it urgent? (Priority Suggestion)
β‘ **Urgency**: **HIGH**. π₯ CVSS Score implies High Confidentiality & Integrity impact. With low exploitation complexity and no auth required, immediate patching or mitigation is critical!
