FKIE_CVE-2025-34171
Vulnerability from fkie_nvd - Published: 2026-01-02 17:15 - Updated: 2026-10-07 11:10
Severity
Summary
CasaOS versions up to and including 0.4.15 expose multiple unauthenticated endpoints that allow remote attackers to retrieve sensitive configuration files and system debug information. The /v1/users/image endpoint can be abused with a user-controlled path parameter to access files under /var/lib/casaos/1/, which reveals installed applications and configuration details. Additionally, /v1/sys/debug discloses host operating system, kernel, hardware, and storage information. The endpoints also return distinct error messages, enabling file existence enumeration of arbitrary paths on the underlying host filesystem. This information disclosure can be used for reconnaissance and to facilitate targeted follow-up attacks against services deployed on the host.

El punto final /v1/users/image puede ser explotado con un par\u00e1metro de ruta controlado por el usuario para acceder a archivos bajo /var/lib/casaos/1/, lo que revela aplicaciones instaladas y detalles de configuraci\u00f3n. Adem\u00e1s, /v1/sys/debug revela informaci\u00f3n del sistema operativo del host, kernel, hardware y almacenamiento. Los puntos finales tambi\u00e9n devuelven mensajes de error distintos, lo que permite la enumeraci\u00f3n de existencia de archivos de rutas arbitrarias en el sistema de archivos del host subyacente. Esta revelaci\u00f3n de informaci\u00f3n puede utilizarse para reconocimiento y para facilitar ataques de seguimiento dirigidos contra servicios desplegados en el host."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
