KEV: No
Impact: Remote command execution on network device
Action: Patch if available
AI Analysis

Impact

A command injection flaw in the TDDP module of the Deco BE11000 allows an attacker with adjacent network access to send a specially crafted UDP packet that is interpreted by the device’s operating system, enabling arbitrary command execution with root privileges. The flaw is classified as CWE‑78, and successful exploitation may lead to complete device compromise, including unauthorized command execution, modification of device settings, and loss of confidentiality, integrity, and availability.

Affected Systems

TP‑Link Systems Inc. Deco BE11000 V2 is affected. No specific firmware versions are listed, but any device running the current TDDP module is vulnerable.

Risk and Exploitability

The CVSS score of 7.7 indicates high severity, and because the attack is executed from a nearby network using a UDP packet, the required conditions are minimal. The EPSS score of 4% reflects a low but non‑zero exploitation probability, and catalog, suggesting no widespread active exploitation is currently observed. Nonetheless, the potential impact of uncontrolled root access makes the risk significant.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the Deco BE11000 firmware to the latest version that removes the TDDP command injection flaw.
  • Configure the device’s firewall or router to block or restrict UDP traffic destined for the vulnerable port and ensure the TDDP service is not exposed beyond the local network.
  • If a patch is not yet released, isolate the device from untrusted local networks or apply MAC‑based access restrictions to prevent attackers from reaching the vulnerable service.
