PHP remote file inclusion vulnerability in modules/mail/main.php in Inter7 vHostAdmin 1.0 allows remote attackers to execute arbitrary PHP code via a URL in the MODULES_DIR parameter.
vpopmail 5.4.14 and 5.4.15, with cleartext passwords enabled, allows remote attackers to authenticate to an account that does not have a cleartext password set by using a blank password to (1) SMTP AUTH or (2) APOP.
Buffer overflow in qmailadmin.c in QmailAdmin before 1.2.10 allows remote attackers to execute arbitrary code via a long PATH_INFO environment variable.
Cross-site scripting (XSS) vulnerability in SqWebMail 5.0.4 allows remote attackers to inject arbitrary web script or HTML via an e-mail message containing Internet Explorer "Conditional Comments" such as "[if]" and "[endif]".
Cross-site scripting (XSS) vulnerability in SqWebMail 5.0.4 and possibly other versions allows remote attackers to inject arbitrary web script or HTML via an HTML e-mail containing tags with strings that contain ">" or other special characters, which is not properly sanitized by SqWebMail.
Cross-site scripting (XSS) vulnerability in SqWebMail 5.0.4 allows remote attackers to inject arbitrary web script or HTML via a file attachment that is processed by the Display feature. NOTE: the severity of this issue has been disputed by the developer.
SqWebMail allows remote attackers to inject arbitrary web script or HTML via CRLF sequences in the redirect parameter followed by the desired script or HTML.
Format string vulnerability in vsybase.c in vpopmail 5.4.2 and earlier has unknown impact and attack vectors. NOTE: in a followup post, it was observed that the source code used constants that, when compiled, became static format strings. Thus this is not a vulnerability
Inter7 SqWebMail 3.4.1 through 3.6.1 generates different error messages for incorrect passwords versus correct passwords on non-mail-enabled accounts (such as root), which allows remote attackers to guess the root password via brute force attacks.
