ProFTPD: Format string vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200508-02 (ProFTPD: Format string vulnerabilities) "infamous42md" reported that ProFTPD is vulnerable to format string vulnerabilities when displaying a shutdown message containing the name of the current directory, and when displaying response messages to the client using information retrieved from a database using mod_sql. Impact A remote attacker could create a directory with a malicious name that would trigger the format string issue if specific variables are used in the shutdown message, potentially resulting in a Denial of Service or the execution of arbitrary code with the rights of the user running the ProFTPD server. A possible hacker with control over the database contents could achieve the same result by introducing malicious messages that would trigger the other format string issue when used in server responses. Workaround Do not use the "%C", "%R", or "%U" in shutdown messages, and do not set the "SQLShowInfo" directive.
