CVE-2014-2271Network attack vector

Arbitrary Java execution via HTTPS downgrade

Published Jan 14, 2020 · Updated Aug 6, 2024

Improper transport validation in Kingsoft Office 5.3.1 allows man-in-the-middle attackers to execute arbitrary Java code. CloudPrintWebView retries a failed HTTPS registry connection over plaintext HTTP and accepts attacker-modified Google Cloud Printing content. Exploitation requires control of the network path to block HTTPS, and the injected code runs with the application's permissions on Huawei P2 firmware before V100R001C00B043.
