CVE-2025-54134

### Summary The HAX CMS NodeJS application crashes when an authenticated attacker provides an API request lacking required URL parameters. This vulnerability affects the `listFiles` and `saveFiles` endpoints. ### Details This vulnerability exists because the application does not properly handle exceptions which occur as a result of changes to user-modifiable URL parameters. #### Affected Resources • [listFiles.js:22](https://github.com/haxtheweb/haxcms-nodejs/blob/main/src/routes/listFiles.js#L22) listFiles() • [saveFile.js:52](https://github.com/haxtheweb/haxcms-nodejs/blob/main/src/routes/saveFile.js#L52) saveFile() • system/api/listFiles • system/api/saveFile ### PoC 1. Targeting an instance of instance of [HAX CMS NodeJS](https://github.com/haxtheweb/haxcms-nodejs), send a request without parameters to `listFiles` or `saveFiles`. The following screenshot shows the request in Burp Suite.  2. The server will crash with `ERR_INVALID_ARG_TYPE`.  ### Impact An authenticated attacker can deny access to the HAX CMS NodeJS application by crashing the backend server. This prevents all users from accessing the backend system. If the backend system is hosting websites, those websites will be unavailable.

HAX CMS NodeJS permite a los usuarios gestionar su universo de micrositios con un backend NodeJS. En las versiones 11.0.8 y anteriores, la aplicación HAX CMS NodeJS se bloquea cuando un atacante autenticado proporciona una solicitud de API sin los parámetros de URL requeridos. Esta vulnerabilidad afecta a los endpoints listFiles y saveFiles. Esta vulnerabilidad existe porque la aplicación no gestiona correctamente las excepciones que se producen como resultado de cambios en los parámetros de URL modificables por el usuario. Esto se ha corregido en la versión 11.0.9.
