A stored cross-site scripting (XSS) vulnerability in the web management interface of the Digi PortServer TS, Digi One SP, Digi One SP IA, and Digi One IA allows a remote, authenticated administrator to inject script into certain system configuration fields. The script subsequently executes in the browser of a user who views the affected pages (CWE-79).
Improper authentication handling was identified in a set of HTTP POST requests affecting the following product families:
Digi PortServer TS - prior to and including 82000747AA, build date 06/17/2022
Digi One SP/Digi One SP IA/Digi One IA - prior to and including 82000774Z, build date 10/19/2020
Digi One IAP – prior to and including 82000770 Z, build date 10/19/2020
A specially crafted POST request to the device’s web interface may allow an unauthenticated attacker to modify configuration settings.
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 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.
