Official Description

Improper path validation in promecefpluginhost.exe in Kingsoft WPS Office version ranging from 12.2.0.13110 to 12.2.0.17115 (exclusive) on Windows allows an attacker to load an arbitrary Windows library.

The patch released in version 12.1.0.17119 to mitigate CVE-2024-7262 was not restrictive enough. Another parameter was not properly sanitized which leads to the execution of an arbitrary Windows library.

Technical Analysis

CVE-2024-7263 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
