InfraSuite Device Master: Insufficiently Protected Credentials
CVE-2023-1137 is a high-severity insufficiently protected credentials vulnerability in InfraSuite Device Master from Delta Electronics, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.0.5 as the first without the flaw, so updating InfraSuite Device Master to that release or later removes the exposure. There is no confirmed exploitation so far.

The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
