Arbitrary Code Execution in WPS Office
Noroxi assessment
Priority: This week (action score 68/100)
- CISA has confirmed exploitation in the wild (Sep 3, 2024). Remediation deadline for US federal agencies: Sep 24, 2024.
- Probability of exploitation in the next 30 days: 2.9% (FIRST EPSS); higher than 86.7% of all records.
- Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Improper path validation in promecefpluginhost.exe in Kingsoft WPS Office version ranging from 12.2.0.13110 to 12.2.0.16412 (exclusive) on Windows allows an attacker to load an arbitrary Windows library. The vulnerability was found weaponized as a single-click exploit in the form of a deceptive spreadsheet document

Actively exploited in the wild
CISA added this to its Known Exploited Vulnerabilities catalog on Sep 3, 2024. That signals real attacks, not theory.
Remediation deadline for government agencies: Sep 24, 2024.
