Title
Pi-Hole AdminLTE Whitelist (now 'Web Allowlist') Remote Command Execution
Summary
An authenticated command injection vulnerability exists in Pi-hole versions up to 3.3. When adding a domain to the allowlist via the web interface, the domain parameter is not properly sanitized, allowing an attacker to append OS commands to the domain string. These commands are executed on the underlying operating system with the privileges of the Pi-hole service user.
This behavior was present in the legacy AdminLTE interface and has since been patched in later versions.
Severity ?

Summary
Pi-hole before 6 allows unauthenticated admin/api.php?setTempUnit= calls to change the temperature units of the web dashboard. NOTE: the supplier reportedly does "not consider the bug a security issue" but the specific motivation for letting arbitrary persons change the value (Celsius, Fahrenheit, or Kelvin), seen by the device owner, is unclear.

CVE-2024-28247 (GCVE-0-2024-28247)

Title
Pihole Authenticated Arbitrary File Read with root privileges
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.

Title
Stored XSS Vulnerability in the Pi-hole Webinterface
Summary
Pi-hole's Web interface provides a central location to manage a Pi-hole instance and review performance statistics. Prior to Pi-hole Web interface version 5.5.1, the function to add domains to blocklists or allowlists is vulnerable to a stored cross-site-scripting vulnerability. User input added as a wildcard domain to a blocklist or allowlist is unfiltered in the web interface. Since the payload is stored permanently as a wildcard domain, this is a persistent XSS vulnerability. A remote attacker can therefore attack administrative user accounts through client-side attacks. Pi-hole Web Interface version 5.5.1 contains a patch for this vulnerability.
Severity ?
5.7 (Medium)
CWE
- CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Title
(Authenticated) Remote Code Execution Possible in Web Interface 5.5
Summary
Pi-hole's Web interface provides a central location to manage a Pi-hole instance and review performance statistics. Prior to Pi-hole Web interface version 5.5.1, the `validDomainWildcard` preg_match filter allows a malicious character through that can be used to execute code, list directories, and overwrite sensitive files. The issue lies in the fact that one of the periods is not escaped, allowing any character to be used in its place. A patch for this vulnerability was released in version 5.5.1.

CVE-2020-14971 (GCVE-0-2020-14971)
Vulnerability from nvd – Published: 2020-06-23 13:41 – Updated: 2024-08-04 13:00
VLAI?
Summary
Pi-hole through 5.0 allows code injection in piholedhcp (the Static DHCP Leases section) by modifying Teleporter backup files and then restoring them. This occurs in settings.php. To exploit this, an attacker would request a backup of limited files via teleporter.php. These are placed into a .tar.gz archive. The attacker then modifies the host parameter in dnsmasq.d files, and then compresses and uploads these files again.
Severity ?
No CVSS data available.

CVE-2025-34087 (GCVE-0-2025-34087)
Vulnerability from cvelistv5 – Published: 2025-07-03 19:46 – Updated: 2025-11-19 14:36

Title
Pi-Hole AdminLTE Whitelist (now 'Web Allowlist') Remote Command Execution
Summary
An authenticated command injection vulnerability exists in Pi-hole versions up to 3.3. When adding a domain to the allowlist via the web interface, the domain parameter is not properly sanitized, allowing an attacker to append OS commands to the domain string. These commands are executed on the underlying operating system with the privileges of the Pi-hole service user.
This behavior was present in the legacy AdminLTE interface and has since been patched in later versions.
Severity ?
CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Title
Pihole Authenticated Arbitrary File Read with root privileges
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.

CVE-2021-32793 (GCVE-0-2021-32793)

Title
Stored XSS Vulnerability in the Pi-hole Webinterface
Summary
Pi-hole's Web interface provides a central location to manage a Pi-hole instance and review performance statistics. Prior to Pi-hole Web interface version 5.5.1, the function to add domains to blocklists or allowlists is vulnerable to a stored cross-site-scripting vulnerability. User input added as a wildcard domain to a blocklist or allowlist is unfiltered in the web interface. Since the payload is stored permanently as a wildcard domain, this is a persistent XSS vulnerability. A remote attacker can therefore attack administrative user accounts through client-side attacks. Pi-hole Web Interface version 5.5.1 contains a patch for this vulnerability.
Severity ?
5.7 (Medium)
CWE
- CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Title
(Authenticated) Remote Code Execution Possible in Web Interface 5.5
Summary
Pi-hole's Web interface provides a central location to manage a Pi-hole instance and review performance statistics. Prior to Pi-hole Web interface version 5.5.1, the `validDomainWildcard` preg_match filter allows a malicious character through that can be used to execute code, list directories, and overwrite sensitive files. The issue lies in the fact that one of the periods is not escaped, allowing any character to be used in its place. A patch for this vulnerability was released in version 5.5.1.

CVE-2020-14971 (GCVE-0-2020-14971)
Vulnerability from cvelistv5 – Published: 2020-06-23 13:41 – Updated: 2024-08-04 13:00
VLAI?
Summary
Pi-hole through 5.0 allows code injection in piholedhcp (the Static DHCP Leases section) by modifying Teleporter backup files and then restoring them. This occurs in settings.php. To exploit this, an attacker would request a backup of limited files via teleporter.php. These are placed into a .tar.gz archive. The attacker then modifies the host parameter in dnsmasq.d files, and then compresses and uploads these files again.
Severity ?
No CVSS data available.
