In the ProFTPD FTP server identified<\/a><\/noindex> a dangerous vulnerability (CVE-2019-12815<\/a><\/noindex>), which allows copying files within the server without authentication using the commands \u00absite cpfr\u00bb and \u00absite cpto\u00bb. The issue has been assigned<\/a><\/noindex> a severity level of 9.8 out of 10, as it can be exploited for remote code execution if anonymous FTP access is provided.<\/p>\n

The vulnerability is caused by<\/a><\/noindex> incorrect access control checks for reading and writing data (Limit READ and Limit WRITE) in the mod_copy module, which is enabled by default and included in the proftpd packages for most distributions. Notably, the vulnerability results from a not fully resolved similar issue, discovered<\/a><\/noindex> in 2015, for which new attack vectors have now been identified. Moreover, the issue was reported to developers back in September of last year, but the patch was prepared<\/a><\/noindex> only released a few days ago.<\/p>\n

The problem also manifests in the latest stable releases of ProFTPd 1.3.6 and 1.3.5d. A fix is available in the form of a patch<\/a><\/noindex>. As a workaround, it is recommended to disable mod_copy in the configuration. The vulnerability has currently been fixed only in Alpine<\/a><\/noindex> and remains unfixed in Debian<\/a><\/noindex>, Arch<\/a><\/noindex>, Ubuntu<\/a><\/noindex>, FreeBSD<\/a><\/noindex>, EPEL-7<\/a><\/noindex> (ProFTPD is not supplied in the main RHEL repository, and the package from EPEL-6 is not affected by the issue as it does not include mod_copy).<\/p>\n
