Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Unauthenticated Path Traversal in HSC Mailinspector. ๐ **Consequences**: Attackers can read arbitrary files on the server, potentially exposing sensitive data like credentials or configs.โฆ
๐ก๏ธ **CWE**: CWE-22 (Path Traversal). ๐ **Flaw**: The `/public/loader.php` file fails to sanitize the `path` parameter. It doesn't verify if the requested file is within the webroot, allowing `../` traversal.
Q3Who is affected? (Versions/Components)
๐ข **Vendor**: HSC Cybersecurity. ๐ฆ **Product**: HC Mailinspector (Cloud Email Security). ๐ **Affected Versions**: 5.2.17-3 through 5.2.18. โ ๏ธ **Scope**: All versions up to 5.2.18 are vulnerable.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Action**: Read any file accessible by the web server process. ๐ **Data**: OS files, config files, source code. ๐ **Privileges**: No authentication required. Low barrier to entry for data theft.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: LOW. ๐ช **Auth**: None required (Unauthenticated). โ๏ธ **Config**: Standard web access is enough. ๐ฏ **Ease**: Simple payload injection (`../`) makes it easy to exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฅ **Exploit**: YES. ๐ **PoC**: Multiple public PoCs on GitHub (e.g., osvaldotenorio, bigb0x). ๐ ๏ธ **Tools**: Bulk scanners and automated tools (CVEHunter) are available for mass exploitation.โฆ
๐ **Check**: Send request to `/mailinspector/public/loader.php` with `path=../../../../etc/passwd`. ๐ **Scan**: Use Python scripts from GitHub repos to scan single or bulk targets.โฆ
๐ก๏ธ **Fix**: Upgrade to version > 5.2.18. ๐ **Patch**: Official patch released by HSC Cybersecurity. โ **Status**: Fixed in newer versions. ๐ **Action**: Immediate update recommended.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If patching is delayed, restrict access to `/public/loader.php` via WAF or firewall rules. ๐ซ **Block**: Block external access to this specific endpoint.โฆ
