Out-of-Bounds Access in Omada Switch Web Interface Enables RCE

Publication date: 2026-03-13

Last updated on: 2026-04-02

Assigner: TPLink

Description
The web interface on multiple Omada switches does not adequately validate certain external inputs, which may lead to out-of-bound memory access when processing crafted requests. Under specific conditions, this flaw may result in unintended command execution.<br>An unauthenticated attacker with network access to the affected interface may cause memory corruption, service instability, or information disclosure. Successful exploitation may allow remote code execution or denial-of-service.

Executive Summary

This vulnerability affects the web interface of multiple Omada switch models. It occurs because the interface does not properly validate certain external inputs, which can lead to out-of-bound memory access when processing specially crafted requests.

Under specific conditions, this flaw may cause unintended command execution. An unauthenticated attacker with network access to the affected interface can exploit this vulnerability to cause memory corruption, service instability, or information disclosure.

Successful exploitation could result in remote code execution or denial-of-service (DoS) attacks.

Impact Analysis

If exploited, this vulnerability can have serious impacts including:

  • Memory corruption on the affected device.
  • Service instability, potentially causing the device to crash or behave unpredictably.
  • Information disclosure, which could expose sensitive data.
  • Remote code execution, allowing an attacker to run arbitrary commands on the device.
  • Denial-of-service (DoS) attacks, making the device unavailable for legitimate use.

Mitigation Strategies

To mitigate this vulnerability, users are strongly advised to update affected Omada switch devices to the latest firmware versions that address the issue.

Devices operating in Standalone mode can update via the local web interface.

Devices operating in Controller mode (using Omada Controller or Omada app) will receive automatic update notifications and can apply updates directly through the controller.

Firmware files are also available for manual download from the Omada website for different regions (US, EN, AU).

Failure to apply these updates leaves devices vulnerable to exploitation.
