DiGi Web Server allows remote attackers to cause a denial of service (CPU consumption) via an HTTP GET request that contains a large number of / (slash) characters, which consumes resources when DiGi converts the slashes to \ (backslash) characters.

IP-in-IP protocol allows a remote, unauthenticated attacker to route arbitrary network traffic

IP-in-IP protocol specifies IP Encapsulation within IP standard (RFC 2003, STD 1) that decapsulate and route IP-in-IP traffic is vulnerable to spoofing, access-control bypass and other unexpected behavior due to the lack of validation to verify network packets before decapsulation and routing.

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 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 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.

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.

Digi ConnectPort X2D

An attacker may be able to execute malicious actions due to the lack of device access protections and device permissions when using the web application. This could lead to uploading python files which can be later executed.

Digi RealPort Protocol Use of Password Hash Instead of Password for Authentication

Digi RealPort Protocol is vulnerable to a replay attack that may allow an attacker to bypass authentication to access connected equipment.

Digi Passport Firmware through 1.5.1,1 is affected by a buffer overflow. An attacker can supply a string in the page parameter for reboot.asp endpoint, allowing him to force an overflow when the string is concatenated to the HTML body.

Digi Passport Firmware through 1.5.1,1 is affected by a buffer overflow in the function for building the Location header string when an unauthenticated user is redirected to the authentication page.

Digi PortServer TS 16 Improper Authentication

Properly formatted POST requests to multiple resources on the HTTP and HTTPS web servers of the Digi PortServer TS 16 Rack device do not require authentication or authentication tokens. This vulnerability could allow an attacker to enable the SNMP service and manipulate the community strings to achieve further control in.

An issue was discovered on Digi TransPort Gateway devices through 5.2.13.4. They do not set the Secure attribute for sensitive cookies in HTTPS sessions, which could cause the user agent to send those cookies in cleartext over an HTTP session.

An issue was discovered on Digi TransPort devices through 2021-07-21. An authenticated attacker may load customized firmware (because the bootloader does not verify that it is authentic), changing the behavior of the gateway.

An issue was discovered on Digi TransPort devices through 2021-07-21. An authenticated attacker may read a password file (with reversible passwords) from the device, which allows decoding of other users' passwords.

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 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 TransPort DR64, SR44 VC74, and WR. The ZING protocol allows arbitrary remote command execution with SUPER privileges. This allows an attacker (with knowledge of the protocol) to execute arbitrary code on the controller including overwriting firmware, adding/removing users, disabling the internal firewall, etc.

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 TransPort WR21 5.2.2.3, WR44 5.1.6.4, and WR44v2 5.1.6.9 devices allow stored XSS in the web application.

Digi International ConnectPort LTS 32 MEI, Firmware Version 1.4.3 (82002228_K 08/09/2018), bios Version 1.2. Successful exploitation of this vulnerability could allow an attacker to upload a malicious file to the application.
