Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A code injection flaw in Rejetto HTTP File Server (HFS).โฆ
๐ก๏ธ **Root Cause**: Improper handling of **null bytes** (`%00`) in `parserLib.pas`. <br>๐ **Flaw**: The `findMacroMarker` function fails to sanitize input, allowing command injection. โ ๏ธ
๐ป **Capabilities**: Attackers gain the ability to **execute arbitrary programs**. <br>๐ **Privileges**: Remote Code Execution (RCE) without authentication. ๐ต๏ธโโ๏ธ
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **LOW**. <br>๐ **Auth**: No authentication required. <br>๐ก **Config**: Exploitable via remote search operations containing `%00`. ๐
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Public Exp**: **YES**. <br>๐ **PoCs**: Multiple Python scripts available on GitHub (e.g., `cve-2014-6287.py`). <br>๐ง **Metasploit**: Module exists. ๐ฅ
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for Rejetto HFS services. <br>๐งช **Test**: Look for version **2.3c** or lower. <br>๐ **Indicator**: Check for `parserLib.pas` usage in server responses. ๐ต๏ธโโ๏ธ
Q8Is it fixed officially? (Patch/Mitigation)
๐ ๏ธ **Fix**: Upgrade to a version **newer than 2.3c**. <br>โ **Official**: Patch released by vendor. ๐ฆ
Q9What if no patch? (Workaround)
๐ง **Workaround**: If unpatched, **disable** the HFS service or restrict network access via firewall. <br>๐ซ **Block**: Prevent external access to port 80/443. ๐
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**. <br>โก **Priority**: High. <br>๐ข **Reason**: Easy remote exploitation with no auth needed. Immediate action required! ๐โโ๏ธ
