Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Unauthenticated PHP code injection in MetInfo CMS. ๐ฅ **Consequences**: Remote attackers can execute arbitrary code, leading to **complete server takeover**.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: CWE-94 (Improper Control of Generation of Code). โ ๏ธ **Flaw**: Insufficient input neutralization allows malicious PHP code injection via crafted requests.
๐ **Privileges**: Remote code execution (RCE) with no authentication required. ๐ **Data**: Full control over the server, access to all data, and potential lateral movement.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **LOW**. โ๏ธ **Config**: No authentication (PR:N), low complexity (AC:L), no user interaction (UI:N). Easily exploitable remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Exploit**: Yes. Public PoC available via Nuclei templates. ๐ **Status**: Exploitation requires crafting specific HTTP requests with malicious PHP payloads.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for MetInfo CMS versions 7.9-8.1. ๐งช **Test**: Use Nuclei template `CVE-2026-29014.yaml` to detect unauthenticated injection points.
Q8Is it fixed officially? (Patch/Mitigation)
๐ฉน **Patch**: Update to a patched version immediately. ๐ **Note**: Official vendor site (metinfo.cn) should be checked for security advisories.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If unpatched, restrict web server access to trusted IPs only. ๐ **Mitigate**: Implement WAF rules to block PHP code injection patterns in input fields.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**. ๐ **Priority**: CVSS 9.8 (High). Immediate action required due to ease of exploitation and severe impact (RCE).
