Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Quarkus framework has a security flaw in the `quarkus-security-webauthn` module. ๐ **Consequences**: Default REST endpoints remain enabled, leading to potential **arbitrary user login** attacks.โฆ
๐ก๏ธ **Root Cause**: **CWE-288** (Authentication Bypass). The specific flaw is the **default REST endpoint not being disabled** in the WebAuthn security module. โ ๏ธ Misconfiguration by default!
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: Applications using the **Quarkus** framework, specifically those utilizing the `quarkus-security-webauthn` module. ๐ณ Cloud-native Java apps on Linux containers are at risk.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: Hackers can bypass authentication mechanisms. ๐ญ They can achieve **arbitrary user login**, gaining unauthorized access to user accounts and sensitive data without valid credentials.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **LOW**. ๐ 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)
๐ฆ **Public Exploit**: **No**. The `pocs` field is empty in the provided data. ๐ซ No public Proof-of-Concept or wild exploitation code is currently available based on this record.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Quarkus apps using the `quarkus-security-webauthn` module. ๐ Verify if the default WebAuthn REST endpoints are exposed and **not disabled** in the configuration.
Q8Is it fixed officially? (Patch/Mitigation)
๐ฉน **Official Fix**: **Yes**. Red Hat has acknowledged the issue (RHBZ#2330484). ๐ Published on 2025-05-06. Users should check for official patches or updates from the vendor.
Q9What if no patch? (Workaround)
๐ **No Patch Workaround**: Manually **disable the default REST endpoints** in the `quarkus-security-webauthn` module configuration. ๐ Restrict network access to these endpoints if possible.
Q10Is it urgent? (Priority Suggestion)
โก **Urgency**: **HIGH**. ๐ฅ CVSS Score implies High Confidentiality & Integrity impact. With low exploitation complexity and no auth required, immediate patching or mitigation is critical!
