CVE-2021-32793 1 Pi-hole 1 Pi-hole 2024-11-21 5.7 Medium
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.
CVE-2021-32706 1 Pi-hole 1 Pi-hole 2024-11-21 7.6 High
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-2021-29449 1 Pi-hole 1 Pi-hole 2024-11-21 6.3 Medium
Pi-hole is a Linux network-level advertisement and Internet tracker blocking application. Multiple privilege escalation vulnerabilities were discovered in version 5.2.4 of Pi-hole core. See the referenced GitHub security advisory for details.
CVE-2021-29448 1 Pi-hole 3 Ftldns, Pi-hole, Web Interface 2024-11-21 7.6 High
Pi-hole is a Linux network-level advertisement and Internet tracker blocking application. The Stored XSS exists in the Pi-hole Admin portal, which can be exploited by the malicious actor with the network access to DNS server. See the referenced GitHub security advisory for patch details.
CVE-2020-8816 1 Pi-hole 1 Pi-hole 2024-11-21 7.2 High
Pi-hole Web v4.3.2 (aka AdminLTE) allows Remote Code Execution by privileged dashboard users via a crafted DHCP static lease.
CVE-2020-35659 1 Pi-hole 1 Pi-hole 2024-11-21 6.1 Medium
The DNS query log in Pi-hole before 5.2.2 is vulnerable to stored XSS. An attacker with the ability to directly or indirectly query DNS with a malicious hostname can cause arbitrary JavaScript to execute when the Pi-hole administrator visits the Query Log or Long-term data Query Log page.
CVE-2020-35592 1 Pi-hole 1 Pi-hole 2024-11-21 5.4 Medium
Pi-hole 5.0, 5.1, and 5.1.1 allows XSS via the Options header to the admin/ URI. A remote user is able to inject arbitrary web script or HTML due to incorrect sanitization of user-supplied data and achieve a Reflected Cross-Site Scripting attack against other users and steal the session cookie.
CVE-2020-35591 1 Pi-hole 1 Pi-hole 2024-11-21 5.4 Medium
Pi-hole 5.0, 5.1, and 5.1.1 allows Session Fixation. The application does not generate a new session cookie after the user is logged in. A malicious user is able to create a new session cookie value and inject it to a victim. After the victim logs in, the injected cookie becomes valid, giving the attacker access to the user's account through the active session.
CVE-2020-14971 1 Pi-hole 1 Pi-hole 2024-11-21 7.8 High
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.
CVE-2020-14162 1 Pi-hole 1 Pi-hole 2024-11-21 7.8 High
An issue was discovered in Pi-Hole through 5.0. The local www-data user has sudo privileges to execute the pihole core script as root without a password, which could allow an attacker to obtain root access via shell metacharacters to this script's setdns command.
CVE-2020-12620 1 Pi-hole 1 Pi-hole 2024-11-21 7.8 High
Pi-hole 4.4 allows a user able to write to /etc/pihole/dns-servers.conf to escalate privileges through command injection (shell metacharacters after an IP address).
CVE-2020-11108 1 Pi-hole 1 Pi-hole 2024-11-21 8.8 High
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.
CVE-2019-13051 1 Pi-hole 1 Pi-hole 2024-11-21 8.8 High
Pi-Hole 4.3 allows Command Injection.
