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.

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.

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.
