CVE-2020-28476
Detail
Rejected
CVE has been marked "REJECT" in the CVE List. These CVEs are stored in the NVD, but do not show up in search results.
Current Description
Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-23336. Reason: This candidate is a reservation duplicate of CVE-2021-23336. Notes: All CVE users should reference CVE-2021-23336 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage
All versions of package tornado are vulnerable to Web Cache Poisoning by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
