How do I patch CVE-2024-7262?

Apply the kingsoft wps office security patch or hotfix for CVE-2024-7262 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2024-7262 across my infrastructure?

Inventory every kingsoft wps office deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2024-7262 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2024-7262?

O3 detects and blocks CVE-2024-7262 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2024-7262 actively exploited in the wild?

Yes. There are 2 known exploit references for CVE-2024-7262, including 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2024-7262?

CVE-2024-7262 has an EPSS (Exploit Prediction Scoring System) score of 1.8%, placing it in the 76th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Is CVE-2024-7262 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2024-7262 (Kingsoft WPS Office Path Traversal Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2024-09-03. CISA required all US federal civilian agencies to remediate this vulnerability by 2024-09-24. The required action was: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2024-7262?

CVE-2024-7262 is classified as Path Traversal (CWE-22). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2024-7262?
