Vulnerability Summary

CVE ID: CVE-2025-47945
Severity: Critical (CVSS score 9.1)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Full account takeover, potential system compromise, and data leakage

Affected Products

Product | Affected Versions

Donetick | Prior to version 0.1.44

How the Exploit Works

The vulnerability arises from the application’s use of JSON Web Tokens (JWT) for user authentication. In versions of the application prior to 0.1.44, the JWT signing secret has a weak default value. The onus is on the system administrator to change this value to something more secure. However, this approach is inadequate and has led to the vulnerability being present in the live version of the app. If an attacker can predict or brute force the JWT signing key, they can generate valid JWTs and impersonate any user of the application, leading to a potential full account takeover.

Conceptual Example Code

The following is a conceptual example of how an attacker might exploit this vulnerability:

POST /user/login HTTP/1.1
Host: vulnerable-donetick.com
Content-Type: application/json
{ "username": "victim", "jwt": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c" }

In this example, the attacker sends a POST request to the login endpoint of the vulnerable Donetick application. The attacker supplies a malicious JWT (in this case, a JWT they have generated using the weak default signing secret) in place of a legitimate JWT, allowing them to impersonate the victim.

Mitigation and Conclusion

The vulnerability has been addressed in version 0.1.44 of Donetick, and it is strongly recommended that users update to this version as soon as possible. As a temporary mitigation, Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can be used to monitor and block malicious traffic. However, these measures should not replace the need for patching and updating the application. By staying current with updates and adopting strong cybersecurity practices, users can significantly reduce the risk posed by vulnerabilities such as CVE-2025-47945.

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Account takeover, potential system compromise, and data leakage

Affected Products

Product | Affected Versions

RAGFlow | 0.18.1 and below

How the Exploit Works

The exploit takes advantage of a key vulnerability in the email verification process of RAGFlow. Specifically, the system generates six-digit codes for account registration, login, and password reset actions. An attacker can conduct successful brute-force attacks against these codes, as there is no rate limiting in place to limit the number of attempts that can be made. This lack of rate limiting allows attackers to attempt all possible six-digit combinations until they find the correct code, facilitating unauthorized access to user accounts.

Conceptual Example Code

The following pseudocode provides a conceptual example of how an attacker might exploit this vulnerability:

for attempt in range(1000000):  # A six-digit code has one million possibilities
verification_code = str(attempt).zfill(6)  # Pad with leading zeros
response = requests.post(
'https://target.example.com/verify',
data={'verification_code': verification_code},
)
if response.status_code == 200:
print(f'Success! The verification code is {verification_code}.')
break

In this example, the attacker iteratively generates and sends verification codes from 000000 to 999999 to the verification endpoint until they receive a successful response.

Mitigation Guidance

Users of RAGFlow are strongly advised to update to the latest version of the software, which contains a patch addressing this vulnerability. In situations where immediate patching is not feasible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. These systems can be configured to detect and block abnormal amounts of verification attempts, thereby preventing successful brute-force attacks. However, these measures are not a substitute for patching the underlying vulnerability.

Affected Products

Product | Affected Versions

Crawlomatic Multipage Scraper Post Generator Plugin for WordPress | Up to and including 2.6.8.1

How the Exploit Works

The vulnerability stems from the lack of file type validation in the `crawlomatic_generate_featured_image()` function of the Crawlomatic Multipage Scraper Post Generator plugin. This oversite allows unauthenticated users to upload arbitrary files to the server where the WordPress site is hosted.
Armed with this loophole, an attacker could upload a malicious file, for instance, a PHP script, which when executed, may enable them to gain control over the system or leak sensitive data.

Conceptual Example Code

A potential exploit could involve a malicious HTTP POST request. The attacker would send a request to upload a file to the server, which, due to the lack of validation, gets accepted and saved on the server. The conceptual example code might look like this:

POST /wp-content/plugins/crawlomatic/upload.php HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.php"
Content-Type: application/x-php
<?php
// Malicious PHP code here...
?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In this example, a malicious PHP file is uploaded via a multipart/form-data POST request to the vulnerable plugin’s upload endpoint. The malicious PHP file could contain code designed to compromise the system or exfiltrate data.
