CVE-2020-10112Public exploitNetwork attack vector

Disputed cache poisoning via parameter-insensitive caching

Published Mar 6, 2020 · Updated Aug 4, 2024

Cache poisoning in Citrix Gateway 11.1, 12.0, and 12.1 allows remote attackers to serve cached responses across parameter values. The reported caching path reuses the first response for later requests to the same URL even when submitted parameter values differ. A victim must request that URL during its cache lifetime; Citrix disputes any security impact because default caching covers only static-content paths.
