"value": "Chamilo is a learning management system. Prior to version 1.11.30, a stored cross-site scripting (XSS) vulnerability exists due to insufficient sanitization of CSV filenames. An attacker can upload a maliciously named CSV file (e.g., \u003cimg src=q onerror=prompt(8)\u003e.csv) that leads to JavaScript execution when viewed by administrators or users with access to import logs or file views. This issue has been patched in version 1.11.30."

Antes de la versi\u00f3n 1.11.30, existe una vulnerabilidad de secuencias de comandos entre sitios (XSS) almacenada debido a una desinfecci\u00f3n insuficiente de los nombres de los archivos CSV. Un atacante puede cargar un archivo CSV con un nombre malicioso (por ejemplo, .csv) que provoca la ejecuci\u00f3n de JavaScript cuando lo ven los administradores o usuarios con acceso a los registros de importaci\u00f3n o a la visualizaci\u00f3n de archivos. Este problema se ha solucionado en la versi\u00f3n 1.11.30."

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.
