CVE-2025-8264 โ€” AI Deep Analysis Summary

CVSS 9.0 ยท Critical

Q1What is this vulnerability? (Essence + Consequences)

๐Ÿšจ **Essence**: Z-Push < 2.7.6 suffers from **SQL Injection** due to unparameterized queries. ๐Ÿ“‰ **Consequences**: Full database compromise, data theft, or system takeover via S:C (Scope Change) impact.

Q2Root Cause? (CWE/Flaw)

๐Ÿ›ก๏ธ **Root Cause**: **CWE-89** (SQL Injection). The flaw lies in using raw SQL strings instead of prepared statements/parameterized queries in the backend logic. ๐Ÿ’”

Q3Who is affected? (Versions/Components)

๐Ÿ“ฆ **Affected**: **Z-Push** versions **prior to 2.7.6**. ๐Ÿข **Product**: `z-push/z-push-dev` by Z-Hub. ๐Ÿ“… **Published**: July 29, 2025.

Q4What can hackers do? (Privileges/Data)

๐Ÿ’€ **Attacker Capabilities**: Read/Modify/Delete any DB data. ๐Ÿ”„ **Privileges**: High impact on Confidentiality, Integrity, and Availability. Can potentially escalate to remote code execution depending on DB config.

Q5Is exploitation threshold high? (Auth/Config)

๐Ÿ”“ **Threshold**: **Low**. CVSS shows **PR:N** (No Privileges Required) and **AV:N** (Network Access). ๐ŸŒ No user interaction needed. Just network access to the Z-Push endpoint.

Q6Is there a public Exp? (PoC/Wild Exploitation)

๐Ÿงช **Exploit Status**: **No public PoC** listed in data. ๐Ÿ“ However, detailed analysis exists in vendor PRs and security blogs (Snyk, Xbow). โš ๏ธ Exploitation logic is likely known/trivial for SQLi.

Q7How to self-check? (Features/Scanning)

๐Ÿ” **Self-Check**: Scan for **Z-Push** endpoints. ๐Ÿ› Look for SQLi patterns in `backend/imap/user_identity.php` (Line ~211). ๐Ÿ“ก Use SQLi scanners against sync endpoints.

Q8Is it fixed officially? (Patch/Mitigation)

โœ… **Fix**: **Yes**. Patched in **Z-Push 2.7.6**. ๐Ÿ“ฅ **Mitigation**: Upgrade immediately. ๐Ÿ“Ž Reference: GitHub PR #161.

Q9What if no patch? (Workaround)

๐Ÿšง **No Patch?**: Implement **WAF rules** to block SQLi payloads. ๐Ÿ›‘ Restrict network access to Z-Push ports. ๐Ÿงน Manually sanitize inputs in `user_identity.php` if source access is available.

Q10Is it urgent? (Priority Suggestion)

๐Ÿ”ฅ **Urgency**: **HIGH**. CVSS is high (likely 8.0+). ๐Ÿšจ **S:C** means impact spreads. ๐Ÿƒโ€โ™‚๏ธ **Action**: Patch NOW. Do not wait for PoC release.
