cn.wps.moffice.common.beans.print.CloudPrintWebView in Kingsoft Office 5.3.1, as used in Huawei P2 devices before V100R001C00B043, falls back to HTTP when the HTTPS connection to the registry fails, which allows man-in-the-middle attackers to conduct downgrade attacks and execute arbitrary Java code by leveraging a network position between the client and the registry to block HTTPS traffic.

The Kingsoft Clip (Office Tool) (aka cn.wps.clip) application 1.5.1 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The WStr::assign function in kso.dll in Kingsoft WPS Office 10.1.0.7106 and 10.2.0.5978 does not validate the size of the source memory block before an _copy call, which allows remote attackers to cause a denial of service (access violation and application crash) via a crafted (a) web page, (b) office document, or (c) .rtf file.

An exploitable use-after-free vulnerability exists in WPS Spreadsheets ( ET ) as part of WPS Office, version 11.2.0.10351. A specially-crafted XLS file can cause a use-after-free condition, resulting in remote code execution. An attacker needs to provide a malformed file to the victim to trigger the vulnerability.

wpsupdater.exe in Kingsoft WPS Office through 11.2.0.10382 allows remote code execution by modifying HKEY_CURRENT_USER in the registry.
