Huatian Dynamic OA8000 collaborative office system contains an unauthenticated path traversal vulnerability in /OAapp/jsp/trace/ntkodownload.jsp, where the filename request parameter is used to locate a file without restricting access to an intended directory or rejecting traversal sequences. Attackers can supply ../ sequences to read arbitrary files from the server, such as the Tomcat configuration at ROOT/WEB-INF/web.xml, exposing sensitive configuration, source, and credential material that can enable further compromise. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-11-20.
Exploitation: PoC · Automatable: yes · Technical impact: partial, assessed 2026-11-13. From CISA's Vulnrichment in the CVE List: whether it is exploited, whether exploiting it can be automated, and how much control it gives.

Show the promptExplain CVE-2024-58406 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2024-58406?via=ask-ai-copy and https://cve.bz/cve/CVE-2024-58406?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2024-58406 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.
