CVE-2026-25858

Comprehensive Technical Analysis of CVE-2026-25858

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2026-25858 CVSS Score: 9.8

The vulnerability in macrozheng mall version 1.0.3 and prior is classified as an authentication flaw in the password reset workflow. The severity of this vulnerability is rated at 9.8 on the CVSS scale, indicating a critical risk. This high score is justified by the potential for unauthenticated attackers to reset arbitrary user account passwords using only a victim’s telephone number, leading to remote account takeover.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The attacker does not need to be authenticated to exploit this vulnerability.
• Telephone Number Enumeration: The attacker can use known or guessable telephone numbers to initiate the password reset process.
• OTP Exposure: The one-time password (OTP) is exposed directly in the API response, allowing the attacker to capture it.

Exploitation Methods:

1. Telephone Number Collection: The attacker collects or guesses the telephone number of the target user.
2. Password Reset Initiation: The attacker initiates the password reset process using the victim’s telephone number.
3. OTP Capture: The attacker captures the OTP from the API response.
4. Password Reset: The attacker uses the captured OTP to reset the victim’s password, gaining unauthorized access to the account.

3. Affected Systems and Software Versions

Affected Software:

• macrozheng mall version 1.0.3 and prior

Affected Systems:

• Any system running the affected versions of macrozheng mall, particularly those with the mall-portal component enabled.

4. Recommended Mitigation Strategies

Immediate Actions:

1. Upgrade Software: Upgrade to a patched version of macrozheng mall that addresses this vulnerability.
2. Disable Password Reset: Temporarily disable the password reset functionality until a patch is applied.
3. Monitor API Responses: Implement monitoring to detect and alert on unauthorized access attempts and OTP exposure in API responses.

Long-Term Mitigations:

1. Enhanced Authentication: Implement multi-factor authentication (MFA) for password reset processes.
2. OTP Security: Ensure OTPs are not exposed in API responses and are securely transmitted to the user.
3. User Verification: Add additional verification steps to confirm the identity and ownership of the telephone number before allowing password resets.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2026-25858 highlights the critical importance of secure authentication and password reset mechanisms. This vulnerability underscores the need for robust identity verification processes and secure handling of sensitive information such as OTPs. The potential for remote account takeover poses significant risks to user data and system integrity, emphasizing the necessity for proactive security measures and regular vulnerability assessments.

6. Technical Details for Security Professionals

Vulnerability Details:

• Root Cause: The password reset workflow in macrozheng mall exposes the OTP in the API response and validates password reset requests solely by comparing the provided OTP to a value stored by telephone number, without verifying user identity or ownership of the telephone number.
• Exploitation Steps:
  1. Initiate password reset using the victim’s telephone number.
  2. Capture the OTP from the API response.
  3. Submit the captured OTP to reset the victim’s password.
• Detection: Monitor API logs for unauthorized access attempts and OTP exposure. Implement intrusion detection systems (IDS) to detect and alert on suspicious activities related to password reset processes.
• Remediation: Apply the latest security patches and updates from the vendor. Implement additional security controls such as MFA and secure OTP transmission methods.
