https://notcve.org/view.php?id=CVE-2021-24002
When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. Cuando un usuario hacía clic en una URL de FTP conteniendo caracteres de nueva línea codificados (%0A y %0D), las nuevas líneas se interpretaban como tales y permitían que comandos arbitrarios fueran enviados al servidor FTP. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 78.10, Thunderbird versiones anteriores a 78.10 y Firefox versiones anteriores a 88 • https://bugzilla.mozilla.org/show_bug.cgi?id=1702374 https://www.mozilla.org/security/advisories/mfsa2021-14 https://www.mozilla.org/security/advisories/mfsa2021-15 https://www.mozilla.org/security/advisories/mfsa2021-16 https://access.redhat.com/security/cve/CVE-2021-24002 https://bugzilla.redhat.com/show_bug.cgi?id=1951369 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •
