Descriptions

F-Secure Software Updater 2.20, as distributed in several F-Secure products, downloads installation packages over plain http and does not perform file integrity validation after download. Man-in-the-middle attackers can replace the file with their own executable which will be executed under the SYSTEM account. Note that when Software Updater is configured to install updates automatically, it checks if the downloaded file is digitally signed by default, but does not check the author of the signature. When running in manual mode (default), no signature check is performed.

F-Secure Software Updater 2.20, tal como se distribuye en varios productos F-Secure, descarga paquetes de instalación sobre http simple y no realiza la validación de integridad del archivo después de la descarga. Atacantes man-in-the-middle pueden reemplazar el archivo con su propio ejecutable que se ejecutará bajo la cuenta SYSTEM. Tenga en cuenta que cuando Software Updater está configurado para instalar actualizaciones automáticamente, comprueba si el archivo descargado está firmado digitalmente de forma predeterminada, pero no comprueba el autor de la firma. Cuando se ejecuta en modo manual (predeterminado), no se realiza ninguna comprobación de firma.
