Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Zerobyte (v<0.18.5 & v<0.19.0) has a critical auth bypass flaw. π **Consequences**: Attackers can access sensitive backup data without credentials. Total loss of confidentiality & integrity! π₯
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-305 (Auth Bypass). π **Flaw**: The authentication middleware was **not correctly applied** to specific API endpoints. π« Security check was skipped!
Q3Who is affected? (Versions/Components)
π₯ **Affected**: Users of **Nico (nicotsx)**'s Zerobyte software. π¦ **Versions**: All versions **before 0.18.5** AND all versions **before 0.19.0**. β οΈ Check your version immediately!
Q4What can hackers do? (Privileges/Data)
π **Hacker Power**: Full **Authentication Bypass**. π **Privileges**: Can act as an admin/user. π **Data**: High risk of reading/storing backup files. CVSS Score: **High** (C:H, I:H).
π« **Public Exp?**: No PoC provided in data. π **Refs**: GitHub Issue #161 & GHSA advisory exist. π΅οΈββοΈ **Status**: Theoretical/Confirmed, but no wild exploit code yet. Stay alert!
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Zerobyte API endpoints. π§ͺ **Test**: Try accessing backup APIs without tokens. π‘ **Indicator**: If API responds without 401/403, you are vulnerable! π¨
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed?**: Yes! π οΈ **Patch**: Update to **v0.18.5+** or **v0.19.0+**. π **Commit**: See commit `13e080a` for the fix. π₯ Upgrade NOW!
Q9What if no patch? (Workaround)
π§ **No Patch?**: Block external access to API ports. π **WAF**: Filter requests lacking valid auth headers. ποΈ **Isolate**: Segment the network hosting Zerobyte. π‘οΈ Mitigate risk!
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. π¨ **Priority**: P1. π’ **Action**: Patch immediately. CVSS is High, and auth bypass is a top-tier threat. Don't wait! β³
