Descriptions

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, Cacti calls `compat_password_hash` when users set their password. `compat_password_hash` use `password_hash` if there is it, else use `md5`. When verifying password, it calls `compat_password_verify`. In `compat_password_verify`, `password_verify` is called if there is it, else use `md5`. `password_verify` and `password_hash` are supported on PHP < 5.5.0, following PHP manual. The vulnerability is in `compat_password_verify`. Md5-hashed user input is compared with correct password in database by `$md5 == $hash`. It is a loose comparison, not `===`. It is a type juggling vulnerability. Version 1.2.27 contains a patch for the issue.

Cacti proporciona un framework de monitoreo operativo y gestión de fallas. Antes de la versión 1.2.27, Cacti llama a `compat_password_hash` cuando los usuarios establecen su contraseña. `compat_password_hash` usa `password_hash` si lo hay, de lo contrario usa `md5`. Al verificar la contraseña, llama a `compat_password_verify`. En `compat_password_verify`, se llama a `password_verify` si existe; de lo contrario, use `md5`. `password_verify` y `password_hash` son compatibles con PHP &lt; 5.5.0, siguiendo el manual de PHP. La vulnerabilidad está en `compat_password_verify`. La entrada del usuario con hash Md5 se compara con la contraseña correcta en la base de datos mediante `$md5 == $hash`. Es una comparación vaga, no `===`. Es un tipo de vulnerabilidad que hace malabarismos. La versión 1.2.27 contiene un parche para el problema.

It was discovered that Cacti did not properly apply checks to the "Package Import" feature. An attacker could possibly use this issue to perform arbitrary code execution. This issue only affected Ubuntu 24.04 LTS, Ubuntu 22.04 LTS, Ubuntu 20.04 LTS and Ubuntu 18.04 LTS. It was discovered that Cacti did not properly sanitize values when using javascript based API. A remote attacker could possibly use this issue to inject arbitrary javascript code resulting into cross-site scripting vulnerability. This issue only affected Ubuntu 24.04 LTS.
