Vulnerability from fkie_nvd - Published: 2025-04-09 12:15 - Updated: 2025-07-15 19:08
Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
Improper Input Validation vulnerability in Apache POI. The issue affects the parsing of OOXML format files like xlsx, docx and pptx. These file formats are basically zip files and it is possible for malicious users to add zip entries with duplicate names (including the path) in the zip. In this case, products reading the affected file could read different data because 1 of the zip entries with the duplicate name is selected over another but different products may choose a different zip entry. This issue affects Apache POI poi-ooxml before 5.4.0. poi-ooxml 5.4.0 has a check that throws an exception if zip entries with duplicate file names are found in the input file. Users are recommended to upgrade to version poi-ooxml 5.4.0, which fixes the issue. Please read https://poi.apache.org/security.html for recommendations about how to use the POI libraries securely.

En este caso, los productos que lean el archivo afectado podr\u00edan leer datos diferentes, ya que se selecciona una de las entradas zip con el nombre duplicado en lugar de otra, pero otros productos podr\u00edan elegir una entrada zip diferente. Este problema afecta a Apache POI poi-ooxml anterior a la versi\u00f3n 5.4.0. poi-ooxml 5.4.0 tiene una comprobaci\u00f3n que genera una excepci\u00f3n si se encuentran entradas zip con nombres de archivo duplicados en el archivo de entrada.
