Description
An incorrect authorization vulnerability exists in multiple WSO2 products due to a business logic flaw in the account recovery-related SOAP admin service. A malicious actor can exploit this vulnerability to reset the password of any user account, leading to a complete account takeover, including accounts with elevated privileges. This vulnerability is exploitable only through the account recovery SOAP admin services exposed via the "/services" context path in affected products. The impact may be reduced if access to these endpoints has been restricted based on the "Security Guidelines for Production Deployment" by disabling exposure to untrusted networks.

1. Vulnerability Assessment and Severity Evaluation
Vulnerability Description: The vulnerability EUVD-2024-54595 (CVE-2024-6914) is an incorrect authorization flaw in the account recovery-related SOAP admin service of multiple WSO2 products. This flaw allows a malicious actor to reset the password of any user account, leading to a complete account takeover, including accounts with elevated privileges.
Severity Evaluation:
- Base Score: 9.8
- Base Score Version: 3.1
- Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
The CVSS score of 9.8 indicates a critical vulnerability. The high severity is due to the following factors:
- 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)
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network-Based Attacks: The vulnerability can be exploited remotely over the network.
- Unauthenticated Access: No prior authentication is required to exploit this vulnerability.
Exploitation Methods:
- Password Reset: An attacker can send a specially crafted SOAP request to the account recovery service to reset the password of any user account.
- Account Takeover: Once the password is reset, the attacker can log in as the user and gain full control over the account, including accessing sensitive information and performing actions with elevated privileges.
3. Affected Systems and Software Versions
The vulnerability affects multiple WSO2 products and versions, including but not limited to:
- WSO2 Carbon Identity Management: Versions 5.7.5 < 5.7.5.9, 5.12.387 < 5.12.387.41, etc.
- WSO2 Identity Server: Versions 5.6.0 < 5.6.0.56, 5.7.0 < 5.7.0.122, etc.
- WSO2 API Manager: Versions 3.1.0 < 3.1.0.292, 3.2.0 < 3.2.0.382, etc.
- WSO2 Open Banking KM: Versions 1.4.0 < 1.4.0.129, 1.5.0 < 1.5.0.119, etc.
- WSO2 IoT: Versions 3.3.1 < 3.3.1.61, 3.3.0 < 3.3.0.59, etc.
