[原文]Rockliffe MailSite Express before 6.1.22, with the option to save login information enabled, saves user passwords in plaintext in cookies, which allows local users to obtain passwords by reading the cookie file, or remote attackers to obtain the cookies via cross-site scripting (XSS) vulnerabilities.
MailSite Express contains a flaw that may lead to an unauthorized information disclosure. The issue is that the user's password is stored in a cookie file in plaintext. This can allow local users to obtain passwords by reading the cookie file, or can be used in conjunction with the XSS vulnerability (OSVDB ID 20488) to steal the user's password remotely, resulting in a loss of confidentiality.
Upgrade to version 6.1.22 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
