๐ก๏ธ **Root Cause**: Insecure handling of leftover installation artifacts. ๐ **Flaw**: Access to `installer.php` and `installer-backup.php` allows input manipulation during DB setup.โฆ
๐ฏ **Target**: WordPress sites using Snap Creek Duplicator. ๐ฆ **Affected Versions**: All versions **before 1.2.42**. ๐ซ **Fixed**: Version 1.2.42 and later are safe.
Q4What can hackers do? (Privileges/Data)
๐ **Privileges**: Full control via RCE. ๐พ **Data**: Can read/write any file, execute system commands, and steal database credentials. ๐ธ๏ธ **Impact**: Complete site compromise.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Auth**: No authentication required. ๐ **Config**: Only requires access to the leftover installer URLs (`/installer.php`, `/installer-backup.php`). ๐ **Threshold**: **LOW**. Easy to exploit if files remain.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **PoC**: Yes, public PoCs exist on GitHub (cved-sources) and Nuclei templates. ๐ **Wild Exploitation**: High risk. Automated scanners can detect and exploit this easily.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for existence of `installer.php` or `installer-backup.php`. ๐ ๏ธ **Tool**: Use Nuclei templates (`http/cves/2018/CVE-2018-17207.yaml`). ๐ **Manual**: Try accessing these URLs directly in the browser.
Q8Is it fixed officially? (Patch/Mitigation)
