CVE-2025-29046: Buffer Overflow Vulnerability in ALFA WiFi CampPro Router

Overview

The cybersecurity landscape is fraught with complex challenges and potential vulnerabilities. The latest to hit the scene is a Buffer Overflow vulnerability in the ALFA WiFi CampPro router, designated as CVE-2025-29046. This vulnerability has a wide-reaching impact as it affects all users of the ALFA WiFi CampPro router running the ALFA_CAMPRO-co-2.29 version, opening the door for a remote attacker to execute arbitrary code via the GAPSMinute3 key value. Given the ubiquity of ALFA WiFi CampPro routers in both domestic and commercial settings, this vulnerability could have potentially devastating effects.

How the Exploit Works

The exploit takes advantage of a Buffer Overflow vulnerability in the ALFA WiFi CampPro router. A buffer overflow occurs when more data is written to a block of memory, or buffer, than it can hold. This overflow of data can corrupt or overwrite other data, causing erratic program behavior, including memory access errors, incorrect results, or crashes.
In the case of CVE-2025-29046, a remote attacker can execute arbitrary code via the GAPSMinute3 key value. This means that an attacker could potentially gain unauthorized access to the system, leading to a system compromise, and possible data leakage.

Conceptual Example Code

Here’s a
conceptual
example of how the vulnerability might be exploited. This could be a sample HTTP request, where the malicious payload overflows the buffer:

POST /GAPSMinute3 HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "buffer_overflow_payload": "AAAAAAAAA...[continues for a large amount]" }

In this example, the string “A” is sent repeatedly to overflow the buffer and cause the vulnerability to manifest. This is a simplified representation, and actual attacks may involve more complex code and specific payloads designed to cause certain effects, such as executing specific malicious commands.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by monitoring and possibly blocking malicious traffic. However, these are only temporary solutions and cannot fully remediate the vulnerability. Applying the patch should be the priority to ensure the security of your systems.
