Pi-Hole: >> Pi-Hole >> 4.3.4 Security Vulnerabilities
The Gravity updater in Pi-hole through 4.4 allows an authenticated adversary to upload arbitrary files. This can be abused for Remote Code Execution by writing to a PHP file in the web directory. (Also, it can be used in conjunction with the sudo rule for the www-data user to escalate privileges to root.) The code error is in gravity_DownloadBlocklistFromUrl in gravity.sh.
