WLAN AP Driver | All prior versions to the patch

How the Exploit Works

The vulnerability resides in the WLAN AP driver, where an incorrect bounds check may lead to an out-of-bounds write. This error could be exploited by a malicious user already inside the system to escalate their privileges without any required interaction from other users. This privilege escalation could potentially lead to a full system compromise, including data leakage.

Conceptual Example Code

While it’s impossible to provide an exact exploit without risk of misuse, we can conceptually understand how a potential exploit might look. When bounds checking is not properly implemented, a malicious user can inject code that might look something like this:

$ echo "malicious_code" > /dev/wlan0

In this conceptual example, the “malicious_code” is written directly to the device driver file, potentially leading to an overflow due to incorrect bounds checking.

Mitigation and Prevention

The best course of action to prevent exploitation of this vulnerability is to apply the vendor-supplied patch, identified as Patch ID: WCNCR00416937. For temporary mitigation, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may help detect and prevent attempts to exploit this vulnerability. Regular patching and security reviews are integral to maintaining a secure system environment and preventing future vulnerabilities.

Affected Products

Product | Affected Versions

WLAN AP Drivers | All versions prior to patch WCNCR00416936

How the Exploit Works

The vulnerability lies within the bounds check of the WLAN AP driver. An attacker with user-level access could manipulate the bounds check to write data outside of the intended memory area. This error would allow an attacker to perform a privilege escalation, taking control of the system or potentially leading to data leakage. The exploit does not require any user interaction, making it a silent and efficient attack method.

Conceptual Example Code

The following is a pseudocode representation of how the vulnerability might be exploited. Note that this is a conceptual example and does not represent actual exploit code.

# Assumed to have user-level access
def exploit():
driver = connect_to_driver("WLAN AP")
malicious_data = generate_malicious_data()
# Overwrite the bounds check
driver.bounds_check = False
# Write data outside the normal bounds
write_data(driver, malicious_data)

This pseudocode demonstrates the core concepts behind the exploit. It connects to the WLAN AP driver, generates malicious data, disables the bounds check, and then writes the malicious data outside of the normal bounds. This leads to a possible local escalation of privileges, granting the attacker control over the system.

Mitigation and Prevention

The vendor has issued a patch (WCNCR00416936) that addresses this vulnerability. All users of the affected WLAN AP drivers should apply this patch as soon as possible to mitigate the risk. In the interim, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to provide temporary mitigation.
Remember, staying up to date with patches and security updates is one of the most effective methods of preventing cybersecurity vulnerabilities. Regularly check for updates and apply them promptly to ensure the highest level of security for your systems.

Affected Products

Product | Affected Versions

LuaJIT | Up to and including 2.1

How the Exploit Works

The vulnerability in LuaJIT stems from an out-of-bounds read error in the stack-overflow handler within lj_state.c. This essentially means that the software reads data past the end, or before the beginning, of the intended buffer. Such behavior can lead to the program crashing, or worse, an attacker gaining the ability to execute arbitrary code, steal data or cause a Denial of Service (DoS).

Conceptual Example Code

This is a conceptual example illustrating how an attacker could potentially exploit the vulnerability. An attacker might send a specially crafted payload to the LuaJIT interpreter, causing it to read out-of-bounds and thus leading to unintended behavior.

-- Malicious Lua code causing stack overflow
function stack_overflow()
return stack_overflow()
end
stack_overflow()

This code, when run on a vulnerable LuaJIT system, would cause a stack overflow, triggering the problematic behavior in the stack-overflow handler.
Please note that this example is highly simplified for illustrative purposes and actual exploitation of this vulnerability would likely require a more sophisticated approach.

Prevention and Mitigation

The best way to mitigate this vulnerability is to apply the vendor-supplied patch. If a patch is not immediately available or cannot be applied straight away, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as a temporary mitigation measure. These systems can be configured to detect and block attempts to exploit this vulnerability, providing an additional layer of security while the patch is being prepared or deployed.

Product | Affected Versions

WeGIA Web Manager | Versions prior to 3.4.3

How the Exploit Works

The vulnerability lies in the /html/funcionario/profile_funcionario.php endpoint of the WeGIA web application. More specifically, the ‘id_funcionario’ parameter isn’t properly sanitized or validated before being used in a SQL query. As a result, an attacker can manipulate this parameter to inject arbitrary SQL commands. Since no authentication is required, this vulnerability is easily exploitable.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. In this case, the attacker is injecting an SQL statement (`OR ‘1’=’1`) into the ‘id_funcionario’ field:

GET /html/funcionario/profile_funcionario.php?id_funcionario=' OR '1'='1 HTTP/1.1
Host: vulnerable-website.com

When this request is processed by the web server, the SQL statement `OR ‘1’=’1` is inserted into the SQL query, potentially allowing the attacker to bypass authentication mechanisms, view sensitive data, or even execute commands on the underlying system.

Mitigation and Solution

The vulnerability has been fixed in version 3.4.3 of the WeGIA web manager. Users are strongly advised to update to this version or later. As an interim solution, deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help mitigate the potential attack, but these are not long-term solutions and should only be used temporarily until the patch can be applied.

Affected Products

Product | Affected Versions

WeGIA Web Manager |

How the Exploit Works

The vulnerability lies in the ‘almox’ parameter of the /controle/relatorio_geracao.php endpoint of the WeGIA Web Manager. By injecting malicious SQL queries via this parameter, an attacker can manipulate the application’s database, leading to unauthorized access to sensitive data. Given the time-based nature of the SQL Injection, the attacker can infer whether the injection was successful based on the response time of the web application, making it a stealthy and dangerous vulnerability.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited.

POST /controle/relatorio_geracao.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
almox=1; WAITFOR DELAY '00:00:10'--

In this example, the ‘almox’ parameter is set to a malicious SQL query that causes the database to delay its response by 10 seconds. If the web application responds after a noticeable delay, the attacker can infer that the SQL Injection was successful.

Mitigation

The vulnerability has been rectified in WeGIA Web Manager version 3.4.1. Users are strongly encouraged to update their applications to the latest version immediately. As a temporary mitigation, users can also employ Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) to block or alert on suspicious SQL queries. However, these measures are not foolproof and updating the application to a patched version is the best course of action.
