    Impact: Local Escalation of Privileges leading to potential system compromise or data leakage

    Affected Products

    Product | Affected Versions

    [Product A] | [Version X]
    [Product B] | [Version Y]

    How the Exploit Works

    The vulnerability stems from the lack of proper input validation in the wl_update_hidden_ap_ie() function of wl_cfgscan.c. It allows an attacker to write out of the bounds of an allocated data structure, which could lead to local escalation of privilege. Although no additional execution privileges are needed, the exploit could potentially compromise the system or cause data leakage.

    Conceptual Example Code

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

    #include <stdio.h>
#include <string.h>
void wl_update_hidden_ap_ie(int index, char *data, int length){
char buffer[256];
if(length > 256) { // Improper validation
printf("Data length too long\n");
return;
}
memcpy(buffer, data, length); // Out of bounds write if length > 256
}
int main(){
char malicious_data[300];
memset(malicious_data, 'A', 300);
wl_update_hidden_ap_ie(0, malicious_data, 300); // Exploiting the vulnerability
return 0;
}

    This code attempts to copy more data to the buffer than it can hold, leading to an out-of-bounds write, which is where the vulnerability lies.

    Mitigation Guidance

    The best remedy against this exploit is to apply a vendor patch if one is available. If not, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Implementing proper input validation and boundary checks can also help to prevent such vulnerabilities.

    Here is a conceptual example of how the vulnerability might be exploited. This is a representation of a malicious file that could be used to trigger the vulnerability.

    import java.io.*;
import java.util.*;
public class Exploit{
public static void main(String[] args) {
try {
ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/c", "your malicious command");
Process p = pb.start();
} catch (IOException e) {
e.printStackTrace();
}
}
}

    This Java code would be serialized into a file, which would then be imported into FRENIC-Loader 4. The deserialization vulnerability would allow the execution of the arbitrary code contained within the file.

    Mitigation

    Users are urged to apply the latest patch provided by the vendor, Fuji Electric, which addresses this vulnerability. As a temporary mitigation measure, users can also employ Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) to detect and prevent attempted exploits.
