CVE-2025-57205 (GCVE-0-2025-57205)

Vulnerability from cvelistv5 – Published: 2025-09-22 00:00 – Updated: 2025-09-24 19:06

Summary
iNiLabs School Express (SMS Express) 6.2 is affected by a Stored Cross-Site Scripting (XSS) vulnerability in the content-management features available to authenticated admin users. The vulnerability resides in POSTed editor parameters submitted to the /posts/edit/{id} endpoint (and similarly in Notice and Pages editors). Due to insufficient input sanitization and output encoding, attackers can inject HTML/JS payloads. The payload is saved and later rendered unsanitized, resulting in JavaScript execution in other users' browsers when they access the affected content. This issue allows an authenticated attacker to execute arbitrary JavaScript in the context of another user, potentially leading to session hijacking, privilege escalation, data exfiltration, or administrative account takeover. The application does not enforce a restrictive Content Security Policy (CSP) or adequate filtering to prevent such attacks.

La vulnerabilidad reside en los par\u00e1metros de editor POSTeados enviados al endpoint /posts/edit/{id} (y de manera similar en los editores de Avisos y P\u00e1ginas). Debido a una sanitizaci\u00f3n de entrada y codificaci\u00f3n de salida insuficientes, los atacantes pueden inyectar cargas \u00fatiles HTML/JS. La carga \u00fatil se guarda y luego se renderiza sin sanitizar, lo que resulta en la ejecuci\u00f3n de JavaScript en los navegadores de otros usuarios cuando acceden al contenido afectado. Este problema permite a un atacante autenticado ejecutar JavaScript arbitrario en el contexto de otro usuario, lo que podr\u00eda llevar a secuestro de sesi\u00f3n, escalada de privilegios, exfiltraci\u00f3n de datos o toma de control de la cuenta administrativa.

The vulnerability resides in POSTed editor parameters submitted to the /posts/edit/{id} endpoint (and similarly in Notice and Pages editors). Due to insufficient input sanitization and output encoding, attackers can inject HTML/JS payloads. The payload is saved and later rendered unsanitized, resulting in JavaScript execution in other users\u0027 browsers when they access the affected content. This issue allows an authenticated attacker to execute arbitrary JavaScript in the context of another user, potentially leading to session hijacking, privilege escalation, data exfiltration, or administrative account takeover. The application does not enforce a restrictive Content Security Policy (CSP) or adequate filtering to prevent such attacks."

Taxonomy of the tags.




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.
