Official description
If misconfigured, alpitronic Hypercharger EV charging devices can expose a web interface protected by authentication. If the default credentials are not changed, an attacker can use public knowledge to access the device as an administrator.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Use of Default Credentials
The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality.
How developers prevent this class of flaw
- Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
- Force the administrator to change the credential upon installation.
- The product administrator could change the defaults upon installation or during operation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
