Technical Details for CVE-2021-47760
Vulnerability Analysis
This CVE entry has been rejected by its CVE Numbering Authority (CNA) because it was determined to be a duplicate of an existing CVE. When a CVE is marked as rejected with "duplicate" status, it indicates that the same vulnerability was already assigned a different CVE identifier, and that original identifier should be used for all tracking, patching, and remediation activities.
Rejected CVEs are maintained in the database for historical reference and to prevent confusion, but they should not be used for vulnerability assessment or compliance reporting. Security teams encountering this CVE in scan results or advisories should investigate to find the canonical CVE that describes the same underlying issue.
Root Cause
The root cause of this CVE rejection is administrative in nature. During the CVE assignment process, the same vulnerability was inadvertently assigned multiple CVE identifiers. To maintain the integrity of the CVE system and prevent duplicate tracking, the CNA withdrew this entry in favor of the original assignment.
Attack Vector
Since this CVE has been rejected as a duplicate, no attack vector analysis is applicable. Security teams should locate the canonical CVE identifier that supersedes this entry to understand the actual attack vector and exploitation methods for the underlying vulnerability.
