Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Grav CMS v1.7.48 has a critical flaw. π **Consequences**: Attackers can achieve **Remote Code Execution (RCE)**. This means total server compromise via malicious plugin uploads.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Flaw in `/admin/tools/direct-install`. β οΈ **Flaw**: The system allows uploading and executing arbitrary PHP code without sufficient validation. It bypasses security checks for authenticated users.
π **Hacker Power**: Execute **Arbitrary PHP Code**. π **Impact**: Full control over the server. They can steal data, install backdoors, or take down the site completely.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **Medium**. π **Requirement**: Requires **Authenticated Administrator** access. You cannot exploit this anonymously. You need valid admin credentials.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π» **Exploit Status**: **Yes**. π **PoC Available**: Public Proof-of-Concept exists on GitHub (binneko/CVE-2025-50286). Wild exploitation is possible if admin creds are leaked.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: 1. Check Grav version (v1.7.48). 2. Check Admin Plugin (v1.10.48). 3. Verify if `/admin/tools/direct-install` is accessible. 4. Scan for known PoC signatures.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Fix Status**: **Pending/Unknown** in provided data. β³ **Action**: Check Grav CMS official updates immediately. The vendor page (grav.com) is the source of truth for patches.
Q9What if no patch? (Workaround)
π§ **Workaround**: **Disable Direct Install**. π« **Mitigation**: Restrict access to `/admin/tools/direct-install`. Remove admin credentials if compromised. Use WAF rules to block plugin uploads.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. π¨ **Priority**: Patch immediately if admin accounts are exposed. Even with auth requirement, RCE is critical. Monitor for credential leaks.
