Vulnerability Summary

CVE ID: CVE-2025-40682
Severity: Critical (CVSS: 9.8)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Human Resource Management System | Version 1.0

How the Exploit Works

The exploit takes advantage of the lack of proper input validation for the “city” and “state” parameters in the /controller/ccity.php endpoint. An attacker can input malicious SQL code into these parameters, which the system then executes. This allows the attacker to interact directly with the database, enabling them to retrieve, create, update, and delete database entries.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This could be a sample HTTP request:
```
POST /controller/ccity.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
city=NewYork';DROP TABLE Employees;--&state=NY
```
In the above example, the attacker uses the SQL Injection attack to delete the “Employees” table from the database. The semicolon (;) is used to end the original SQL statement, and the ‘–‘ symbol indicates the start of a comment, effectively ignoring the rest of the actual query.

Recommended Mitigation

The most effective mitigation measure is to apply the vendor’s patch. If the patch is not available, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these should be seen as stop-gap measures, and the patch should be applied as soon as it is available to ensure long-term security.

Vulnerability Summary

CVE ID: CVE-2025-6504
Severity: High (CVSS: 8.4)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

HDP Server | Versions below 4.6.2.2978

How the Exploit Works

The exploit hinges on the X-Forwarded-For (XFF) header, a de facto standard for identifying the originating IP address of a client connecting to a web server through an HTTP proxy. This header is client-controlled, meaning that an attacker could spoof it, and if the spoofed IP matches a whitelisted range, unauthorized access could be granted. Therefore, despite IP restrictions, the system becomes vulnerable to potential unauthorized access.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited:
```
GET /restricted/resource HTTP/1.1
Host: vulnerable-server.com
X-Forwarded-For: <spoofed IP>
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64)
Authorization: Bearer <valid user token>
```
In this example, the attacker is using a spoofed IP address in the X-Forwarded-For header to trick the server into thinking the request is coming from a trusted network. The presence of a valid user token (which could have been obtained through other means) makes this attack more likely to succeed.

Recommended Mitigation

As a solution, users of HDP Server versions below 4.6.2.2978 should apply the vendor patch immediately. If immediate patching is not feasible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. These tools can help detect and prevent unauthorized access attempts. Long term, however, patching the system should be considered the definitive solution.

Affected Products

Product | Affected Versions

Memos Application | Up to v0.24.3

How the Exploit Works

The vulnerability stems from the Memos application’s ability to embed markdown images with arbitrary URLs. When a memo containing such an image is viewed by a user, the app would automatically fetch the image URL without the explicit consent or interaction of the user. An attacker could exploit this automatic fetch mechanism by embedding an image URL that points to a server under their control. As the user’s browser sends a request to fetch the image, it divulges sensitive information such as the user’s IP address and the browser User-Agent string, which the attacker can log for malicious purposes.

Conceptual Example Code

Below is a hypothetical malicious markdown input an attacker could use, where `http://attacker-server/` is an attacker-controlled server:
```
![malicious_image](http://attacker-server/image.png)
```
When a user views this memo, the Memos application would automatically send a GET request to fetch the image:
```
GET /image.png HTTP/1.1
Host: attacker-server
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36
```
This request discloses the user’s IP address, User-Agent string, and potentially other sensitive information to the attacker-controlled server.
