CVE-2026-29041
HighSummary
Chamilo to system zarządzania nauczaniem, który przed wersją 1.11.34 był podatny na zdalne wykonanie kodu przez uwierzytelnionego użytkownika. Problem wynikał z niewłaściwej walidacji przesyłanych plików, polegającej jedynie na weryfikacji typu MIME, co umożliwiało przesyłanie plików z kodem wykonywalnym.
Risk Assessment
Organizacja może być narażona na zdalne wykonanie dowolnych poleceń na serwerze przez uwierzytelnionych użytkowników o niskich uprawnieniach, co może prowadzić do poważnych naruszeń bezpieczeństwa.
Recommendation
Zaleca się aktualizację Chamilo LMS do wersji 1.11.34 lub nowszej, aby usunąć tę podatność oraz wdrożenie dodatkowych mechanizmów walidacji przesyłanych plików.

Original NVD description (English source)
Chamilo is a learning management system. Prior to version 1.11.34, Chamilo LMS is affected by an authenticated remote code execution vulnerability caused by improper validation of uploaded files. The application relies solely on MIME-type verification when handling file uploads and does not adequately validate file extensions or enforce safe server-side storage restrictions. As a result, an authenticated low-privileged user can upload a crafted file containing executable code and subsequently execute arbitrary commands on the server. This issue has been patched in version 1.11.34.
