A stored cross-site scripting (XSS) vulnerability exists in the management web interface of WatchGuard Firebox and XTM appliances. A remote attacker can potentially execute arbitrary JavaScript code in the management web interface by sending crafted requests to exposed management ports. This is fixed in Fireware OS 12.8.1, 12.5.10, and 12.1.4.

WatchGuard Firebox and XTM appliances allow a local attacker (that has already obtained shell access) to elevate their privileges and execute code with root permissions. This is fixed in Fireware OS 12.8.1, 12.5.10, and 12.1.4.

WatchGuard Firebox and XTM appliances allow an unauthenticated remote attacker to retrieve sensitive authentication server settings by sending a malicious request to exposed authentication endpoints. This is fixed in Fireware OS 12.8.1, 12.5.10, and 12.1.4.

An integer overflow in WatchGuard Firebox and XTM appliances allows an unauthenticated remote attacker to trigger a buffer overflow and potentially execute arbitrary code by sending a malicious request to exposed management ports. This is fixed in Fireware OS 12.8.1, 12.5.10, and 12.1.4.

WatchGuard Firebox and XTM appliances allow an authenticated remote attacker with unprivileged credentials to modify privileged management user credentials. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

WatchGuard Firebox and XTM appliances allow an unauthenticated remote attacker to delete arbitrary files from a limited set of directories on the system. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

WatchGuard Firebox and XTM appliances allow an authenticated remote attacker with unprivileged credentials to upload files to arbitrary locations. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

A systemd stack-based buffer overflow in WatchGuard Firebox and XTM appliances allows an authenticated remote attacker to potentially execute arbitrary code by initiating a firmware update with a malicious upgrade image. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

A wgagent stack-based buffer overflow in WatchGuard Firebox and XTM appliances allows an authenticated remote attacker to potentially execute arbitrary code by initiating a firmware update with a malicious upgrade image. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

An integer overflow in WatchGuard Firebox and XTM appliances allows an authenticated remote attacker to trigger a heap-based buffer overflow and potentially execute arbitrary code by initiating a firmware update with a malicious upgrade image. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

WatchGuard Firebox and XTM appliances allow an authenticated remote attacker with unprivileged credentials to retrieve certificate private keys. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2.

The authentication applet in Watchguard Fireware 11.11 Operating System has reflected XSS (this can also cause an open redirect).

A Cross-site Scripting (XSS) vulnerability exists in WatchGuard XTM 11.8.3 via the poll_name parameter in the firewall/policy script.
