Overview
As cybersecurity threats continue to evolve, it is crucial to keep abreast of the latest vulnerabilities that could potentially compromise your data or systems. One such vulnerability, CVE-2025-26199, affects CloudClassroom-PHP-Project v1.0 and exposes sensitive credentials during the login process. This flaw is especially significant as it could allow a remote attacker to capture login credentials using Man-in-the-Middle (MitM) techniques. If these credentials are used to exploit administrative functions, it could potentially lead to remote code execution, depending on the environment.

How the Exploit Works
The vulnerability arises from the insecure transmission of login credentials. When a user attempts to log into the application, the password is transmitted over unencrypted HTTP. This exposes the credentials to potential interception by network-based attackers. An attacker with access to the same network, such as public Wi-Fi or a compromised router, can employ Man-in-the-Middle (MitM) techniques to capture these login credentials. If the attacker uses these credentials to log in and exploit administrative functions, such as file upload, it may lead to remote code execution depending on the environment.
Conceptual Example Code
Here is a simplified example of a HTTP request that could be captured by an attacker:
POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin&password=unencryptedpasswordIn this example, an attacker with access to the same network can intercept this request, gaining the username and password. The attacker can then use these credentials to log into the application and potentially exploit further vulnerabilities.
Mitigation
To mitigate the risk of this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, this does not completely eliminate the risk, so the vendor patch should be applied as soon as possible.
