CVE-2024-56316
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 · uneditedIn AXESS ACS (Auto Configuration Server) through 5.2.0, unsanitized user input in the TR069 API allows remote unauthenticated attackers to cause a permanent Denial of Service via crafted TR069 requests on TCP port 9675 or 7547. Rebooting does not resolve the permanent Denial of Service.
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 · high confidenceThe AXESS ACS (Auto Configuration Server) versions up to 5.2.0 contain an unsanitized user input vulnerability in the TR069 API. Remote unauthenticated attackers can send crafted TR069 requests to TCP ports 9675 or 7547, causing a permanent Denial of Service that cannot be resolved by rebooting the system.

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 AXESS ACS is installedCheck running processes or installed software for 'axess' or 'acs' components. Look for service entries, installed packages, or application directories related to AXESS ACS.Affected if AXESS ACS software is found running or installed on the system
-
Determine the installed AXESS ACS versionQuery the ACS service for its version information, typically via administrative console, service banner, or version file in the installation directory.Affected if The installed version is 5.2.0 or any earlier version (versions up to 5.2.0 are affected)
-
Check if TR069 API ports are listeningScan TCP ports 9675 and 7547 using netstat, nmap, or similar network tools to determine if these TR069 management ports are open and accepting connections.Affected if Port 9675 or 7547 is open and listening on the system
-
Verify TR069 service is enabledInspect the ACS configuration to confirm the TR069 service module is active. Check configuration files or management interface for TR069/ACS service status.Affected if TR069 API service is enabled and operational on the affected ports
-
Assess network exposure of TR069 portsDetermine if ports 9675 and 7547 are accessible from untrusted networks. Review firewall rules, network ACLs, and determine if these ports are exposed to unauthenticated remote attackers.Affected if Ports 9675 or 7547 are accessible from unauthenticated remote network sources without proper access controls
A user is affected if AXESS ACS version 5.2.0 or earlier is installed, the TR069 API is enabled, and ports 9675 or 7547 are exposed to unauthenticated network access.

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 dataRestrict network access to ports 9675 and 7547 through firewall rules or network segmentation to prevent unauthenticated access. Contact the vendor for a patched version addressing the input validation issue in the TR069 API.
