CVE-2024-10498
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 · uneditedCWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists that could allow an unauthorized attacker to modify configuration values outside of the normal range when the attacker sends specific Modbus write packets to the device which could result in invalid data or loss of web interface functionality.
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 confidenceThis is a CWE-119 buffer boundary vulnerability in the Modbus protocol handler. Attackers can send specially crafted Modbus write packets that bypass bounds checking, allowing modification of configuration values outside their intended memory locations. This memory corruption leads to invalid data and can cause complete loss of web interface functionality.

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.
-
Confirm Modbus service is runningCheck system processes or services for Modbus daemon (e.g., 'ps aux | grep modbus' or check service manager for modbus-related services)Affected if Modbus service is actively running and handling protocol requests
-
Verify Modbus write operations are permittedInspect Modbus configuration files or runtime settings for write function codes (0x06, 0x10) - check for any allowlist or restrictions on write operationsAffected if Modbus write operations are enabled without proper restrictions
-
Check for unauthenticated Modbus accessReview Modbus access control configuration (often in config files like modbus.conf, /etc/modbus/, or device web interface settings) for authentication requirementsAffected if Modbus protocol accepts write requests without authentication or network segmentation
-
Assess network exposure of Modbus interfaceCheck firewall rules, network bindings, or device network configuration to determine if Modbus TCP/UDP port (typically 502) is exposed to untrusted networksAffected if Modbus port is accessible from untrusted network segments
-
Identify product version for patch comparisonQuery installed product firmware/software version through device interface, system information command, or version file (common paths: /etc/version, web UI status page, 'uname -a', or vendor-specific command)Affected if Installed version has not been patched for CVE-2024-10498
User is affected if Modbus protocol handler is enabled and accepts unauthenticated write operations without bounds validation on configuration writes.

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 dataImplement proper bounds checking and input validation on all Modbus write operations to ensure configuration values remain within their defined memory boundaries. Restrict Modbus access through authentication or network segmentation to prevent unauthorized packets.
