CVE-2025-1270

Comprehensive Technical Analysis of CVE-2025-1270

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-1270 CISA Vulnerability Name: CVE-2025-1270 CVSS Score: 9.1

The vulnerability in question is an Insecure Direct Object Reference (IDOR) in Anapi Group's h6web software. This type of vulnerability occurs when an application exposes a reference to an internal implementation object, such as a file, directory, database record, or key, as a URL or form parameter. An authenticated attacker can exploit this vulnerability by modifying the “pkrelated” parameter in the “/h6web/ha_datos_hermano.php” endpoint to access other users' information.

Severity Evaluation:

• CVSS Score: 9.1 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates a critical vulnerability that can lead to significant security breaches, including unauthorized access to sensitive information and potential user impersonation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Authenticated User Exploitation: An attacker with valid credentials can manipulate the “pkrelated” parameter to access information belonging to other users.
2. User Impersonation: The initial exploitation can allow the attacker to impersonate other users, leading to further unauthorized actions with the privileges of the impersonated user.

Exploitation Methods:

1. Parameter Tampering: The attacker modifies the “pkrelated” parameter in the POST request to refer to another user's data.
2. Session Hijacking: After the initial exploitation, the attacker can maintain the session as the impersonated user, executing further actions with elevated privileges.

3. Affected Systems and Software Versions

Affected Software:

• Anapi Group's h6web

Affected Versions:

• Specific versions are not mentioned in the provided information. It is crucial to identify the affected versions through further analysis or vendor communication.

4. Recommended Mitigation Strategies

1. Input Validation: Implement robust input validation to ensure that the “pkrelated” parameter and other critical parameters are validated against a whitelist of acceptable values.
2. Access Controls: Enforce strict access controls to ensure that users can only access their own data.
3. Session Management: Implement secure session management practices to prevent session hijacking and impersonation.
4. Patch Management: Apply the latest patches and updates provided by Anapi Group to mitigate the vulnerability.
5. Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities related to parameter tampering and unauthorized access.

5. Impact on Cybersecurity Landscape

The IDOR vulnerability in h6web highlights the importance of secure coding practices and thorough security testing. Organizations relying on h6web or similar software must prioritize vulnerability management and incident response to protect against such critical vulnerabilities. The potential for user impersonation and unauthorized access underscores the need for robust identity and access management (IAM) solutions.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: /h6web/ha_datos_hermano.php
• Parameter: pkrelated
• Exploitation: Modify the pkrelated parameter in a POST request to refer to another user's data.

Detection and Response:

1. Intrusion Detection Systems (IDS): Configure IDS to detect anomalous parameter values and unusual access patterns.
2. Web Application Firewalls (WAF): Deploy WAF rules to block requests with suspicious parameter values.
3. Security Information and Event Management (SIEM): Integrate SIEM to correlate logs and detect potential exploitation attempts.

Remediation Steps:

1. Code Review: Conduct a thorough code review to identify and fix all instances of IDOR vulnerabilities.
2. Penetration Testing: Perform regular penetration testing to identify and mitigate similar vulnerabilities.
3. User Education: Educate users about the risks of parameter tampering and the importance of secure practices.

Conclusion: CVE-2025-1270 represents a critical vulnerability that can be exploited by authenticated attackers to access unauthorized information and impersonate users. Organizations must take immediate action to mitigate this vulnerability by implementing robust security controls and following best practices for secure software development and deployment.
