Official description
SODOLA SL902-SWTGW124AS firmware versions through 200.1.20 contain a default credentials vulnerability that allows remote attackers to obtain administrative access to the management interface. Attackers can authenticate using the hardcoded default credentials without password change enforcement to gain full administrative control of the device.
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: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
