CVE-2024-13980
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedH3C Intelligent Management Center (IMC) versions up to and including E0632H07 contains a remote command execution vulnerability in the /byod/index.xhtml endpoint. Improper handling of JSF ViewState allows unauthenticated attackers to craft POST requests with forged javax.faces.ViewState parameters, potentially leading to arbitrary command execution. This flaw does not require authentication and may be exploited without session cookies. An affected version range is undefined. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-08-28 UTC.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceH3C IMC contains an unauthenticated remote command execution vulnerability in the /byod/index.xhtml endpoint. Attackers can exploit improper JSF ViewState handling by crafting POST requests with forged javax.faces.ViewState parameters, achieving arbitrary command execution without authentication or session cookies.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if H3C IMC is presentCheck your inventory or running services for H3C IMC (also known as H3C Intelligent Management Center). Look for processes listening on common IMC ports (typically 8080, 8443, or 443) or check for IMC web application files on the system.Affected if H3C IMC software is installed and running on the system
-
Determine the installed IMC versionAccess the IMC web interface and look for version information usually found in the About page, help menu, or footer. Alternatively, check version files in the IMC installation directory if accessible.Affected if The installed version is E0632H07 or any version lower than E0632H07 (the summary indicates versions up to E0632H07 are affected)
-
Verify if /byod endpoint is accessibleSend an HTTP GET request to https://<imc-host>/byod/index.xhtml (or http if HTTP is used). Check if the page loads or responds with a 200 OK status.Affected if The /byod/index.xhtml endpoint responds and is reachable from the network
-
Confirm network exposure of IMC management interfaceReview firewall rules, access control lists, or network segmentation to determine if the IMC web interface (port 8080, 8443, or 443) is exposed to untrusted networks or the internet.Affected if The IMC management interface is directly accessible from untrusted networks without VPN or firewall restriction
A system is affected if H3C IMC version E0632H07 or lower is installed and the /byod/index.xhtml endpoint is network-accessible, allowing unauthenticated attackers to exploit the ViewState parameter forgery for remote command execution.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch when available; as interim measures, disable or restrict access to the /byod endpoint, implement WAF rules blocking malicious ViewState payloads, and segment affected systems from untrusted networks.
