SEPPmail Secure Email Gateway before version 15.0.1 insufficiently neutralizes the PDF encryption password, allowing OS command execution.

The GINA web interface in SEPPmail Secure Email Gateway before version 15.0.1 does not properly check attachment filenames in GINA-encrypted emails, allowing an attacker to access files on the gateway.

SEPPmail Secure Email Gateway before 15.0.7 contains a command injection vulnerability that allows authenticated administrators to execute commands with elevated privileges.

SEPPmail Secure Email Gateway before 15.0.6 deserializes attacker-controlled data in a privileged REST import workflow without adequate validation. An attacker with a privileged API token can execute arbitrary commands with "nobody" privileges.

SEPPmail Secure Email Gateway before version 15.0.1 does not properly sanitize the headers from S/MIME protected MIME entities, allowing an attacker to control trusted headers.

SEPPmail Secure Email Gateway before version 15.0.1 improperly validates S/MIME certificates issued for email addresses containing whitespaces, allowing signature spoofing.

SEPPmail Secure Email Gateway before version 15.0.1 incorrectly interprets email addresses in the email headers, causing an interpretation conflict with other mail infrastructure that allows an attacker to fake the source of the email or decrypt it.

SEPPmail Secure Email Gateway before version 15.0.3 allows account takeover by abusing GINA account initialization to reset a victim account password.

SEPPmail Secure Email Gateway before version 15.0.3 does not properly authenticate the inner message of S/MIME-encrypted MIME entities, allowing an attacker to control trusted headers.

SEPPmail Secure Email Gateway before version 15.0.3 allows an attacker to bypass subject sanitization and forge security tags using Unicode lookalike characters.

SEPPmail Secure Email Gateway before version 15.0.3 allows an attacker to cause attacker-controlled certificates to be used for future encryption to a victim by adding the certificates to S/MIME signatures.

SEPPmail Secure Email Gateway before version 15.0.3 allows an attacker to bypass subject sanitization and forge tags such as [signed OK].

SEPPmail Secure Email Gateway before 15.0.7 creates a fully privileged session before required multi-factor authentication enrollment is completed. An attacker with the password for an MFA-required but unenrolled account can access protected functionality without providing a second factor.

SEPPmail Secure Email Gateway before version 15.0.1 decrypts inline PGP messages without isolating them from surrounding unencrypted content, allowing exposure of sensitive information to an unauthorized actor.

SEPPmail Secure Email Gateway before version 15.0.1 does not properly verify that a PGP signature was generated by the expected key, allowing signature spoofing.

SEPPmail Secure Email Gateway before version 15.0.1 does not properly communicate PGP signature verification results, leaving users unable to detect forged emails.

SEPPmail Secure Email Gateway before version 15.0.3 allows an attacker with access to a victim's GINA account to bypass a second-password check and read protected emails.

SEPPmail Secure Email Gateway before version 15.0.3 allows attackers with a specially crafted email address to claim another user's PGP signature as their own.
