Vulnerabilities

An issue in wps office before v.19302 allows a local attacker to obtain sensitive information via a crafted file.

CVE-2024-7262 is a path traversal flaw (CWE-22) caused by improper path validation in promecefpluginhost.exe in Kingsoft WPS Office for Windows, affecting versions from 12.2.0.13110 up to but not including 12.2.0.16412. It is triggered with a single user action: opening a deceptive, weaponized spreadsheet document causes the vulnerable component to load an arbitrary Windows library chosen by the attacker. Loading an attacker-controlled library yields code execution within WPS Office, making this an effective one-click remote code execution vector on Windows. Any Windows user running WPS Office in the affected version range is exposed, and the flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2024-09-03 with a required action of applying vendor mitigations or discontinuing use. Exploitation has been observed in the wild: ESET (the assigning CNA) and news coverage report that the APT-C-60 group used the then-zero-day in campaigns deploying the SpyGlace backdoor, with targeting linked to South Korea.

Do: Upgrade WPS Office for Windows to version 12.2.0.16412 or later, since all builds from 12.2.0.13110 up to (but excluding) that version are vulnerable, and follow Kingsoft's vendor guidance; per CISA KEV, apply vendor mitigations or discontinue use if patching is not possible. Treat unsolicited spreadsheet documents as a delivery vector, and hunt for signs of APT-C-60/SpyGlace activity such as unexpected library loads by promecefpluginhost.exe.

An uninitialized pointer use vulnerability exists in the functionality of WPS Office 11.2.0.11537 that handles Data elements in an Excel file. A specially crafted malformed file can lead to remote code execution. An attacker can provide a malicious file to trigger this vulnerability.

Thinking Software Efence login function has insufficient validation for user input. An unauthenticated remote attacker can exploit this vulnerability to inject arbitrary SQL commands to access, modify or delete database.

OS command injection vulnerability exists in WPS Office version 10.8.0.6186. If a remote attacker who can conduct a man-in-the-middle attack connects the product to a malicious server and sends a specially crafted data, an arbitrary OS command may be executed on the system where the product is installed.

Efence login function has insufficient validation for user input. An unauthenticated remote attacker can exploit this vulnerability to inject arbitrary SQL commands to access, modify or delete database.

WPS Presentation 11.8.0.5745 insecurely load d3dx9_41.dll when opening .pps files('current directory type' DLL loading).

The installer of WPS Office Version 10.8.0.5745 insecurely load shcore.dll, allowing an attacker to execute arbitrary code with the privilege of the user invoking the installer.

The kernel mode driver kwatch3 of KINGSOFT Internet Security 9 Plus Version 2010.06.23.247 fails to properly handle crafted inputs, leading to stack-based buffer overflow.

The installer of WPS Office for Windows versions prior to v11.2.0.10258 fails to configure properly the ACL for the directory where the service program is installed.

GdiDrawHoriLineIAlt in Kingsoft WPS Office before 11.2.0.9403 allows remote heap corruption via a crafted PLTE chunk in PNG data within a Word document. This is related to QBrush::setMatrix in gui/painting/qbrush.cpp in Qt 4.x.

wpsmain.dll in Kingsoft WPS Office 2016 and Jinshan PDF 10.1.0.6621 allows remote attackers to cause a denial of service via a crafted pdf file.

A NULL pointer dereference bug in the function ObReferenceObjectByHandle in the Kingsoft Internet Security 9+ kernel driver KWatch3.sys allows local non-privileged users to crash the system via IOCTL 0x80030030.

Kingsoft WPS Office Free 10.2.0.5978 allows local users to gain privileges or cause a denial of service by impersonating all the pipes through a use of \\.\pipe\WPSCloudSvr\WpsCloudSvr -- an "insecurely created named pipe." Ensures full access to Everyone users group.

The WStr::_alloc_iostr_data() function in kso.dll in Kingsoft WPS Office 10.1.0.7106 and 10.2.0.5978 allows remote attackers to cause a denial of service (application crash) via a crafted (a) web page, (b) office document, or (c) .rtf file.
