In Digi RealPort through 4.10.490, authentication relies on a challenge-response mechanism that gives access to the server password, making the protection ineffective. An attacker may send an unauthenticated request to the server. The server will reply with a weakly-hashed version of the server's access password. The attacker may then crack this hash offline in order to successfully login to the server.
An issue was discovered in Digi RealPort for Windows through 4.8.488.0. A buffer overflow exists in the handling of ADDP discovery response messages. This could result in arbitrary code execution.
Digi RealPort Protocol is vulnerable to a replay attack that may allow an attacker to bypass authentication to access connected equipment.
An issue was discovered in Digi ConnectPort LTS before 1.4.12. A Privilege Escalation vulnerability exists in the file upload feature. It allows an attacker on the local area network (with specific permissions) to upload and execute malicious files, potentially leading to unauthorized system access.
An issue was discovered in the web services of Digi ConnectPort LTS before 1.4.12. It allows an attacker on the local area network to achieve unauthorized manipulation of resources, which may lead to remote code execution when combined with other issues.
An issue was discovered in Digi ConnectPort LTS before 1.4.12. A Directory Traversal vulnerability exists in WebFS. This allows an attacker on the local area network to manipulate URLs to include traversal sequences, potentially leading to unauthorized access to data.
An issue was discovered in Digi RealPort through 4.8.488.0. The 'encrypted' mode is vulnerable to man-in-the-middle attacks and does not perform authentication.
An issue was discovered in Digi ConnectPort LTS before 1.4.12. A vulnerability in the file upload handling of a web application allows manipulation of file paths via POST requests. This can lead to arbitrary file uploads within specific directories, potentially enabling privilege escalation when combined with other vulnerabilities.
