https://notcve.org/view.php?id=CVE-2020-15658
The code for downloading files did not properly take care of special characters, which led to an attacker being able to cut off the file ending at an earlier position, leading to a different file type being downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. El código para descargar archivos no toma cuidado apropiadamente de los caracteres especiales, lo que conllevaba a que un atacante sea capaz de cortar el archivo que terminaba en una posición anterior, conllevando a que sea descargado un tipo de archivo diferente al mostrado en el cuadro de diálogo. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 78.1, Firefox versiones anteriores a 79 y Thunderbird versiones anteriores a 78.1 • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html https://bugzilla.mozilla.org/show_bug.cgi?id=1637745 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-32 https://www.mozilla.org/security/advisories/mfsa2020-33 https://access.redhat.com/security/cve/CVE-2020-15658 https://bugzilla.redhat.com/show_bug.cgi?id=1861647 • CWE-138: Improper Neutralization of Special Elements CWE-754: Improper Check for Unusual or Exceptional Conditions •
