Multiple vulnerabilities have been identified in Eserv, which could be exploited by attackers to bypass security restrictions and gain knowledge of sensitive information.
The first issue is due to directory traversal errors in the IMAP service that does not validate user-supplied arguments passed to the "CREATE", "SELECT", "DELETE", "RENAME", "COPY" and "APPEND" commands, which could be exploited by authenticated users to manipulate arbitrary files and directories.
The second flaw is due to an input validation error when handling a specially crafted filename extension containing dot, space and slash characters, which could be exploited by remote attackers to display the source code of arbitrary files (e.g. PHP) instead of an expected HTML response.
