SmarterTools SmarterMail 16.x through 100.x before 100.0.7803 allows XSS.

SmarterTools SmarterMail 16.x before build 6985 allows deserialization of untrusted data. An unauthenticated attacker could run commands on the server when port 17001 was remotely accessible. This port is not accessible remotely by default after applying the Build 6985 patch.

SmarterTools SmarterMail 16.x before build 6985 has hardcoded secret keys. An unauthenticated attacker could access other users’ emails and file attachments. It was also possible to interact with mailing lists.

SmarterTools SmarterMail 16.x before build 6995 has stored XSS. JavaScript code could be executed on the application by opening a malicious email or when viewing a malicious file attachment.

SmarterTools SmarterMail 16.x before build 6985 allows directory traversal. An authenticated user could delete arbitrary files or could create files in new folders in arbitrary locations on the mail server. This could lead to command execution on the server for instance by putting files inside the web directories.

Unspecified vulnerability in SmarterMail Web Server (SMWebSvr.exe) in SmarterMail 5.0.2999 allows remote attackers to cause a denial of service (service termination) via a long HTTP (1) GET, (2) HEAD, (3) PUT, (4) POST, or (5) TRACE request. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Cross-site scripting (XSS) vulnerability in SmarterTools SmarterMail Enterprise 4.3 allows remote attackers to inject arbitrary web script or HTML via a STYLE attribute of an element in the Subject field of an e-mail message.

SmarterTools SmarterMail before 13.3.5535 was vulnerable to stored XSS by bypassing the anti-XSS mechanisms. It was possible to run JavaScript code when a victim user opens or replies to the attacker's email, which contained a malicious payload. Therefore, users' passwords could be reset by using an XSS attack, as the password reset page did not need the current password.

An issue was discovered in SmarterTools SmarterMail through 100.0.7537. Meddler-in-the-middle attackers can pipeline commands after a POP3 STLS command, injecting plaintext commands into an encrypted user session.

SmarterTools SmarterMail 16.x through 100.x before 100.0.7803 allows remote code execution.

SmarterTools SmarterMail before Build 7776 allows XSS.

SmarterTools SmarterMail 8495 through 8664 before 8747 allows stored XSS by using image/svg+xml and an uploaded SVG document. This occurs because the application tries to allow youtube.com URLs, but actually allows youtube.com followed by an @ character and an attacker-controlled domain name.

SmarterTools SmarterMail 8495 through 8664 before 8747 allows stored XSS via a crafted description of a Calendar appointment.

SmarterTools SmarterMail 8495 through 8664 before 8747 allows stored DOM XSS because an XSS protection mechanism is skipped when messageHTML and messagePlainText are set in the same request.
