Official description
Dell Secure Connect Gateway (SCG) Policy Manager, versions prior to 5.34.00.16, contains a Not Failing Securely ('Failing Open') vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Not Failing Securely
When the product encounters an error condition or failure, its design requires it to fall back to a state that is less secure than other options that are available, such as selecting the weakest encryption algorithm or using the most permissive access control restrictions.
How developers prevent this class of flaw
- Subdivide and allocate resources and components so that a failure in one part does not affect the entire product.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
