CVE-2025-25053: OS command injection vulnerability in Wi-Fi AP UNIT ‘AC-WPS-11ac series

Overview

In this blog post, we will discuss a significant cybersecurity threat that has surfaced recently. The vulnerability, dubbed CVE-2025-25053, affects the Wi-Fi AP UNIT ‘AC-WPS-11ac series’. This flaw could be exploited by a remote attacker who has login access to the product, and could potentially lead to the execution of arbitrary OS commands. Given the widespread use of Wi-Fi AP UNITs, this vulnerability has the potential to affect a significant number of systems with serious consequences such as system compromise or data leakage.

Vulnerability Summary

How the Exploit Works

The exploit works by taking advantage of an OS command injection vulnerability in the WEB UI (the setting page) of the Wi-Fi AP UNIT. When an attacker with login access sends a crafted request to the WEB UI, they can inject arbitrary OS commands. These commands are then executed by the system, potentially leading to unauthorized access, data leakage, or system compromise.

Conceptual Example Code

Let’s illustrate this vulnerability with a conceptual example. An attacker could potentially send a malicious HTTP POST request like the one below. The “malicious_payload” in this case could be an arbitrary OS command.

POST /settings HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer [Attacker's Token]
{ "os_command": "rm -rf /" }

In this example, the “rm -rf /” command is a Unix command that, if executed, would delete all files in the system. This is an extreme example and actual attacks might be more sophisticated, but it illustrates the potential severity of this vulnerability.

Mitigation

The vendor has released a patch to address this vulnerability, which should be applied immediately. As a temporary mitigation, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to block or detect malicious requests. However, these are only temporary solutions and won’t completely protect against this vulnerability. Therefore, it is strongly recommended to apply the vendor patch as soon as possible.
