Name of the Vulnerable Software and Affected Versions SEPPmail Secure Email Gateway versions prior to 15.0.3 Description SEPPmail Secure Email Gateway versions before 15.0.3 are susceptible to an issue that allows an attacker to forge a GINA-encrypted email. Recommendations Update to version 15.0.3 or later.

Name of the Vulnerable Software and Affected Versions SEPPmail Secure Email Gateway versions prior to 15.0.3 Description SEPPmail Secure Email Gateway does not properly authenticate the inner message of S/MIME-encrypted MIME entities, potentially allowing an attacker to control trusted headers. Recommendations Update to version 15.0.3 or later.

**Name of the Vulnerable Software and Affected Versions** SEPPmail Secure Email Gateway versions prior to 15.0.3 **Description** The SEPPmail Secure Email Gateway allows an attacker who has gained access to a victim's GINA account to circumvent a second-password verification and access protected email messages. **Recommendations** Update to version 15.0.3 or later.

**Name of the Vulnerable Software and Affected Versions** SEPPmail Secure Email Gateway versions prior to 15.0.3 **Description** SEPPmail Secure Email Gateway before version 15.0.3 allows an attacker to upload PGP keys where the User ID (UID) does not correspond to the email address associated with the key. This could potentially lead to misuse of the email system. **Recommendations** Update SEPPmail Secure Email Gateway to version 15.0.3 or later.

**Name of the Vulnerable Software and Affected Versions** SEPPmail Secure Email Gateway versions prior to 15.0.3 **Description** SEPPmail Secure Email Gateway before version 15.0.3 has an issue where an external user can modify GINA webdomain metadata, leading to a bypass of per-domain restrictions. **Recommendations** Update SEPPmail Secure Email Gateway to version 15.0.3 or later.

Name of the Vulnerable Software and Affected Versions SEPPmail Secure Email Gateway versions prior to 15.0.3 Description SEPPmail Secure Email Gateway versions before 15.0.3 are susceptible to a flaw where an attacker can create a specially crafted password-tag to circumvent subject sanitization. Recommendations Update to version 15.0.3 or later.

**Name of the Vulnerable Software and Affected Versions** SEPPmail Secure Email Gateway versions prior to 15.0.1 **Description** The SEPPmail Secure Email Gateway does not properly handle PDF encryption passwords, potentially allowing for operating system command execution. The issue arises from insufficient neutralization of the password. **Recommendations** Update to version 15.0.1 or later.

**Name of the Vulnerable Software and Affected Versions** SEPPmail Secure Email Gateway versions prior to 15.0.1 **Description** The GINA web interface does not properly validate attachment filenames within GINA-encrypted emails. This allows an attacker to potentially access files on the gateway. The issue resides in the handling of filenames during the decryption process. The vulnerable component is the GINA web interface. **Recommendations** Update SEPPmail Secure Email Gateway to version 15.0.1 or later.

**Name of the Vulnerable Software and Affected Versions** SEPPmail Secure Email Gateway versions prior to 15.0.1 **Description** The SEPPmail Secure Email Gateway does not correctly handle headers within S/MIME protected MIME entities. This allows an attacker to manipulate trusted headers.
