Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stack-based buffer overflow in EFS Easy File Sharing Web Server. π₯ **Consequences**: Remote attackers can send malicious login requests to `forum.ghp` to execute **arbitrary code** on the target system.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **Stack-based Buffer Overflow**. The software fails to properly validate input lengths when processing specific requests, allowing malicious data to overwrite memory.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **EFS Easy File Sharing Web Server**. Specifically **Version 7.2**. Developed by EFS Software (Netherlands). π Includes forum, file upload/download, and image sharing features.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: **Remote Code Execution (RCE)**. Hackers can gain the same privileges as the application process. This often leads to full system compromise, data theft, or botnet recruitment.
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Exploitation Threshold**: **LOW**. The attack vector is **Remote**. It targets the `forum.ghp` file via a login request.β¦
π **Public Exploit**: **YES**. Exploits are available on **Exploit-DB** (IDs 44522, 44485) and GitHub. A specific PoC exists for **Win 7 Ultimate (x86)** with **DEP bypass** techniques.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **EFS Easy File Sharing Web Server** running on port 80/443. Check for **Version 7.2**. Look for the presence of `forum.ghp` endpoints. Use vulnerability scanners targeting known EFS exploits.
π§ **Workaround**: **Disable the Web Server** if not needed. **Isolate** the server in a DMZ. **Block** external access to the forum/login endpoints via firewall rules.β¦
π₯ **Urgency**: **HIGH**. RCE vulnerabilities with public exploits are critical. Immediate action is required to patch, isolate, or disable the vulnerable service to prevent immediate compromise.
