Comprehensive Technical Analysis of EUVD-2025-34722

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The Truelysell Core plugin for WordPress, versions up to and including 1.8.6, is vulnerable to Arbitrary User Password Change. This vulnerability arises from the plugin's improper handling of user-controlled access to objects, allowing unauthenticated attackers to bypass authorization and access system resources. Specifically, if an attacker knows which page contains the 'truelysell_edit_staff' shortcode, they can change user passwords, potentially leading to the takeover of administrator accounts.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.8, which is considered critical. The CVSS vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high severity score underscores the critical nature of the vulnerability, which can lead to significant impacts on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: An attacker can exploit this vulnerability without needing to authenticate, provided they know the specific page containing the 'truelysell_edit_staff' shortcode.
• Password Change: Once the attacker gains access, they can change user passwords, including those of administrators.
• Privilege Escalation: By changing the password of an administrator account, the attacker can gain full control over the WordPress site.

Exploitation Methods:

• Reconnaissance: The attacker may perform reconnaissance to identify the page containing the 'truelysell_edit_staff' shortcode.
• Exploit Execution: Using the identified page, the attacker can send crafted requests to change user passwords.
• Post-Exploitation: With administrative access, the attacker can perform various malicious activities, such as data exfiltration, defacement, or further compromise of the system.
