An issue in Vanderbilt Industries, Acre Security SPC5300.000 Main Board v.3.14.1 allows a physically proximate attacker to cause a denial of service via spoofed TCP FIN packets without validating the sequence or acknowledgment numbers.
AnalysisAI
TCP connection teardown handling in the Vanderbilt/Acre Security SPC5300.000 Main Board firmware v.3.14.1 accepts spoofed TCP FIN packets without validating sequence or acknowledgment numbers, enabling an attacker in physical or network proximity to forcibly terminate active TCP sessions and cause a denial of service. The affected device is a physical access control security panel, meaning exploitation could disrupt building access control operations. No public exploit code has been identified at time of analysis, and EPSS remains at the 4th percentile, reflecting minimal observed exploitation activity.
Technical ContextAI
The SPC5300.000 is a security panel main board manufactured by Vanderbilt Industries under the Acre Security brand, used in commercial physical access control systems. The vulnerability resides in the device's TCP/IP stack, which fails to validate sequence and acknowledgment numbers when processing TCP FIN (connection teardown) packets - a form of TCP session hijacking or injection. An attacker who can deliver crafted TCP FIN packets to the device can spoof the end of a legitimate TCP connection, causing the panel to tear down active sessions without the legitimate endpoint's consent. CWE-294 (Authentication Bypass by Capture-Replay) is the assigned weakness, though this classification is imprecise; the root cause is closer to CWE-940 (Improper Verification of Source of a Communication Channel) or CWE-290 (Authentication Bypass by Spoofing), since no credential replay is involved - merely packet-level forgery. The NVD CPE entry is unhelpfully listed as 'n/a:n/a', so affected product scope is derived from the description alone.
RemediationAI
No vendor-released patch has been identified at time of analysis - the references point to advisory registration and NVD entries but do not specify a fixed firmware version. Organizations should contact Vanderbilt Industries or Acre Security directly to obtain a patched firmware release for the SPC5300.000 Main Board. As a compensating control, restrict network access to the SPC5300 management interface using firewall rules or VLAN segmentation so that only authorized management stations can reach the device's TCP services - this raises the bar for delivering spoofed FIN packets. Deploying the panel behind a stateful firewall or intrusion prevention system capable of enforcing TCP sequence number validation can also block FIN-injection attacks. Monitor the panel's network interface for anomalous TCP teardown patterns. Note that physical network isolation is particularly effective given the 'physically proximate' language in the description.
