Observed Examples

References	Description
CVE-2002-1976	Linux kernel 2.2 and above allow promiscuous mode using a different method than previous versions, and ifconfig is not aware of the new method (alternate path property).
CVE-2005-1711	Product uses defunct method from another product that does not return an error code and allows detection avoidance.
CVE-2003-0411	chain: Code was ported from a case-sensitive Unix platform to a case-insensitive Windows platform where filetype handlers treat .jsp and .JSP as different extensions. JSP source code may be read because .JSP defaults to the filetype "text".

Vulnerability Mapping Notes

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
