Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Chevereto Core allows **Remote Code Execution (RCE)** via code injection. π **Consequences**: Attackers can fully compromise the server, steal data, and disrupt services. It's a critical security breach.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-94** (Code Injection). The flaw lies in improper handling of the **database table prefix** parameter. Malicious input bypasses sanitization, leading to arbitrary code execution.
Q3Who is affected? (Versions/Components)
π― **Affected**: **Chevereto** (Image Hosting Script). Specifically **Version 3.13.4 Core**. If you are running this version, you are at high risk. Check your installation immediately!
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Full **Remote Code Execution**. Hackers gain the same privileges as the web server process. They can read/write files, execute system commands, and escalate privileges.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Exploitation Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. No authentication required. No user interaction needed. Network-accessible. Extremely easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exploit**: **YES**. ExploitDB ID **47903** is available. VulnCheck advisory also confirms RCE. Wild exploitation is likely given the low barrier to entry.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Chevereto 3.13.4** signatures. Look for the specific **database table prefix** injection points in HTTP requests. Use WAF logs to detect code injection patterns targeting config files.
π§ **No Patch Workaround**: **Isolate** the server. Restrict network access to trusted IPs only. Implement strict **WAF rules** to block SQL/Code injection payloads. Disable unnecessary features.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. CVSS Score is **High** (9.8+ implied by H/H/H). Immediate action required. Patch now or isolate the system. Do not ignore this!
