FKIE_CVE-2016-4027

Vulnerability from fkie_nvd - Published: 2016-12-15 06:59 - Updated: 2026-06-17 00:46
Summary
An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev10. App Suite frontend offers to control whether a user wants to store cookies that exceed the session duration. This functionality is useful when logging in from clients with reduced privileges or shared environments. However the setting was incorrectly recognized and cookies were stored regardless of this setting when the login was performed using a non-interactive login method. In case the setting was enforced by middleware configuration or the user went through the interactive login page, the workflow was correct. Cookies with authentication information may become available to other users on shared environments. In case the user did not properly log out from the session, third parties with access to the same client can access a user's account.

El frontend App Suite ofrece controlar si un usuario quiere almacenar cookies que exceden la duraci\u00f3n de sesi\u00f3n. Esta funcionalidad es \u00fatil cuando se inicia sesi\u00f3n desde clientes con privilegios reducidos o entornos compartidos. Sin embargo la configuraci\u00f3n fue reconocida incorrectamente y las cookies fueron almacenadas independientemente de estos ajustes cuando el inicio de sesi\u00f3n fue realizado usando un m\u00e9todo de inicio de sesi\u00f3n no interactivo. En caso de que el ajuste fuera forzado por la configuraci\u00f3n de middleware o el usuario pas\u00f3 por la p\u00e1gina de inicio de sesi\u00f3n interactiva, el flujo de trabajo era correcto. Las cookies con informaci\u00f3n de autenticaci\u00f3n pueden estar disponibles para otros usuarios en entornos compartidos. En caso de que el usuario no se haya desconectado correctamente de la sesi\u00f3n, los terceros con acceso al mismo cliente pueden acceder a la cuenta de un usuario."

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.

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.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

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.
