- CWE-269 - Improper Privilege Management
Summary
Pi-hole is a Linux network-level advertisement and Internet tracker blocking application. Version 6.4 has a local privilege-escalation vulnerability allows code execution as root from the low-privilege pihole account. Important context: the pihole account uses nologin, so this is not a direct interactive-login issue. However, nologin does not prevent code from running as UID pihole if a Pi-hole component is compromised. In that realistic post-compromise scenario, attacker-controlled content in /etc/pihole/versions is sourced by root-run Pi-hole scripts, leading to root code execution. This vulnerability is fixed in 6.4.1.

- CWE-918 - Server-Side Request Forgery (SSRF)
Summary
Pi-hole is a DNS sinkhole that protects devices from unwanted content without installing any client-side software. A vulnerability in versions prior to 5.18.3 allows an authenticated user to make internal requests to the server via the `gravity_DownloadBlocklistFromUrl()` function. Depending on some circumstances, the vulnerability could lead to remote command execution. Version 5.18.3 contains a patch for this issue.

Summary
The Pi-hole is a DNS sinkhole that protects your devices from unwanted content without installing any client-side software. A vulnerability has been discovered in Pihole that allows an authenticated user on the platform to read internal server files arbitrarily, and because the application runs from behind, reading files is done as a privileged user.If the URL that is in the list of "Adslists" begins with "file*" it is understood that it is updating from a local file, on the other hand if it does not begin with "file*" depending on the state of the response it does one thing or another. The problem resides in the update through local files. When updating from a file which contains non-domain lines, 5 of the non-domain lines are printed on the screen, so if you provide it with any file on the server which contains non-domain lines it will print them on the screen. This vulnerability is fixed by 5.18.
