Vulnerability Summary

CVE ID: CVE-2025-20163
Severity: Critical (8.7 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Cisco Nexus Dashboard Fabric Controller | All versions prior to latest patch

How the Exploit Works

The vulnerability primarily stems from insufficient SSH host key validation in the implementation of Cisco NDFC. This insufficiency provides an opportunity for an attacker to perform a machine-in-the-middle attack on SSH connections to Cisco NDFC-managed devices.
In essence, the attacker intercepts the SSH traffic between the client and server, and due to the lack of proper SSH host key validation, the attacker can successfully impersonate the managed device. This scenario allows the attacker to capture user credentials, potentially leading to system compromise or data leakage.

Conceptual Example Code

Given the nature of the vulnerability, an exact example code is not feasible. However, conceptually, an attacker might exploit the vulnerability as follows:

# Attacker sets up a rogue SSH server to intercept SSH traffic
ssh -i rogue_key -L localhost:22:target_device_IP:22 attacker@rogue_server
# Unsuspecting user connects via SSH
ssh user@localhost
# Attacker captures credentials and impersonates the device

This is, of course, a simplified conceptual example. The actual exploit would involve more complex steps and rely on the specific network configurations and vulnerabilities.

Mitigation Guidance

The best mitigation against this vulnerability is to apply the vendor’s patch. Cisco has already released a patch that corrects the SSH host key validation issue in NDFC. If applying the patch immediately is not feasible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These systems can help identify and block suspicious SSH traffic, reducing the risk of a successful exploit.

User Interaction: None
Impact: Unauthorized access to internal services with elevated privileges, unauthorized system modifications and potential system compromise or data leakage

Affected Products

Product | Affected Versions

Cisco Integrated Management Controller (IMC) for Cisco UCS B-Series | All versions
Cisco Integrated Management Controller (IMC) for Cisco UCS C-Series | All versions
Cisco Integrated Management Controller (IMC) for Cisco UCS S-Series | All versions
Cisco Integrated Management Controller (IMC) for Cisco UCS X-Series Servers | All versions

How the Exploit Works

This vulnerability arises due to an insufficiency in the restrictions on access to internal services within Cisco IMC. An attacker, with a valid user account, can exploit this vulnerability by using specially crafted syntax while connecting to the Cisco IMC of an affected device through SSH. Successful exploitation could result in the attacker gaining access to internal services with elevated privileges.

Conceptual Example Code

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

ssh user@target.example.com
Password: 
<strong></strong>

$ echo "Crafted Syntax" | nc localhost internal_service_port

In this conceptual example, the attacker connects to the target device via SSH and uses the ‘netcat’ command (nc) to send a specially crafted syntax to the internal service running on the ‘internal_service_port’. The ‘crafted syntax’ would be designed to exploit the vulnerability and gain unauthorized access with elevated privileges.

(Note: This is based on inferred data. Please consult vendor advisories for accurate information)

How the Exploit Works

The exploit works by sending an IOCTL request with a buffer size that significantly exceeds the command argument limit. This causes memory corruption, which could allow an attacker to execute arbitrary code on the system or access sensitive data. The attacker could potentially gain unauthorized access to the system and perform malicious activities, including data theft and system compromise.

Conceptual Example Code

Here’s a conceptual example of an IOCTL request that could exploit this vulnerability. This is not actual exploit code but rather a conceptual demonstration of how the vulnerability might be exploited.

#include <sys/ioctl.h>
int main() {
int fd = open("/dev/vulnerable_device", O_RDWR);
char buffer[OVERSIZED_BUFFER_SIZE];
memset(buffer, 'A', sizeof(buffer));
ioctl(fd, VULNERABLE_IOCTL_CMD, buffer);
return 0;
}

In this conceptual example, an oversized buffer filled with ‘A’ characters is passed to the vulnerable IOCTL command. This results in memory corruption, which could lead to system compromise or data leakage.

Mitigation Guidance

To mitigate this vulnerability, it’s recommended to apply the vendor patch as soon as it becomes available. Until then, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure.

Vulnerability Summary

CVE ID: CVE-2025-5482
Severity: High (CVSS: 8.8)
Attack Vector: Network
Privileges Required: Low (Subscriber-level access and above)
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Sunshine Photo Cart Plugin for WordPress | Up to and including 3.4.11

How the Exploit Works

The exploit takes advantage of the plugin’s inadequate user-supplied key validation. An attacker, with at least Subscriber-level access, can manipulate the password reset functionality to change arbitrary user’s passwords, including administrators. This allows the attacker to reset the user’s password and gain unauthorized access to their account.

Conceptual Example Code

Consider the following conceptual HTTP request:

POST /wp-json/sunshine/v1/reset-password HTTP/1.1
Host: victimwebsite.com
Content-Type: application/json
{
"user_id": "1",
"new_password": "malicious_password"
}

In this example, an attacker sends a POST request to the ‘reset-password’ endpoint with a JSON payload containing the user_id of the target (in this case, the administrator with user_id “1”) and a new_password to replace the existing one. The server, failing to properly validate the request, processes the request and resets the user’s password, granting the attacker access to the account.

Mitigation Guidance

Users affected by this vulnerability are advised to apply the vendor patch that has been released to address this issue. If a patch cannot be promptly applied, consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as temporary mitigation. Regularly update and patch all systems and plugins to avoid similar vulnerabilities in the future.

Vulnerability Summary

CVE ID: CVE-2025-4578
Severity: Critical (CVSS 9.8)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise, Data leakage

Affected Products

Product | Affected Versions

File Provider WordPress Plugin |

How the Exploit Works

The vulnerability stems from the plugin’s mishandling of a parameter in its AJAX action. Specifically, the plugin does not appropriately sanitize and escape this parameter before it is used in a SQL statement. Consequently, an attacker can manipulate this parameter to inject malicious SQL code. This code can be executed when the AJAX action is called, giving the attacker the ability to retrieve, manipulate, or delete data from the website’s database.

Conceptual Example Code

The following conceptual code snippet illustrates how the vulnerability might be exploited:

POST /wp-admin/admin-ajax.php?action=file_provider_download HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
file_id=1; DROP TABLE users; --

In this example, the `file_id` parameter is manipulated to include a SQL command (`DROP TABLE users;`) that deletes the `users` table from the database. The `–` at the end of the command signals the rest of the SQL query to be ignored, preventing any syntax errors that might alert to the malicious activity.

Mitigation

The most effective way to mitigate this vulnerability is by applying the patch provided by the vendor. This patch addresses the flaw in the parameter sanitization, thus preventing an attacker from exploiting it to perform a SQL injection. In situations where immediate patching is not feasible, implementing a web application firewall (WAF) or intrusion detection system (IDS) can offer temporary mitigation by identifying and blocking suspected SQL injection attempts.

#include<stdio.h>
#include<string.h>
void exploit() {
char buffer[1000];
memset(buffer, 'A', sizeof(buffer)); // Fill the buffer with 'A's
// Send the buffer data to the VM
send_to_vm(buffer);
}
int main() {
exploit();
return 0;
}

Please note that this is a simplified representation for understanding purposes and actual exploitation might involve more complex methods.

Mitigation Guidance

The most effective way to mitigate the risks associated with CVE-2025-21460 is to apply a patch from the vendor.

Vulnerability Summary

CVE ID: CVE-2025-21453
Severity: High (7.8 CVSS Severity Score)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Windows OS | All versions up to 10.0.19042.867
Linux Kernel | Versions prior to 5.10.17

How the Exploit Works

The exploit works by sending malicious payloads to a targeted system that takes advantage of this memory corruption vulnerability. When the system processes the data structure containing the iterator, it is removed prematurely. If the system then tries to access the iterator after it has been removed, memory corruption occurs. This corruption can then be leveraged by an attacker to execute arbitrary code, potentially leading to system compromise or data leakage.

Conceptual Example Code

The following example illustrates a conceptual malicious payload that might be used to exploit this vulnerability:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "iterator_deletion_trigger" }

In this example, the “malicious_payload” triggers the deletion of the iterator from the data structure. If the system then tries to access this removed iterator, the memory corruption occurs, creating an opening for further exploitation.

Mitigation

The best course of action to mitigate this vulnerability is to apply the vendor-supplied patch. This patch corrects the flaw in the data structure processing that allows for the memory corruption to occur. If the patch cannot be applied immediately, a temporary mitigation could be the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block suspicious network activities.
Remember, staying updated with the latest patches and maintaining a secure network environment is the best defense against these types of vulnerabilities.
