CVE-2025-15624 represents a critical vulnerability within Sparx Systems' Sparx Pro Cloud Server. This vulnerability allows for the insecure storage of user passwords in plaintext format. When OpenID is employed as the primary authentication method for Sparx EA, the Pro Cloud Server generates local passwords and retains them without any encryption. The implications of this flaw are severe, as it exposes sensitive user credentials to potential attackers.
With a CVSS score of 9.3, this vulnerability is classified as critical. The high severity rating indicates that organizations face a significant risk of unauthorized access and data breaches. The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it remotely without physical access to the system. Additionally, the attack complexity is deemed low, which further emphasizes the urgency for organizations to address this vulnerability.
Risk to organizations includes exposure of user credentials, leading to unauthorized access and potential data breaches. Given the critical nature of this vulnerability, organizations should prioritize patching immediately. The vulnerability's exploitation status is currently unknown, but the potential impact is significant enough to warrant immediate attention.
Organizations using Sparx Pro Cloud Server must remain vigilant and take proactive measures to mitigate risks. This includes implementing security best practices and ensuring that user passwords are stored securely, ideally in a hashed format rather than plaintext.
Vulnerability Details
The official CVE description states that the vulnerability involves the plaintext storage of passwords in Sparx Systems Sparx Pro Cloud Server. Specifically, when OpenID is utilized as the primary method of authentication for Sparx EA, local passwords are created and stored in plaintext, which introduces a serious security risk.
The CVSS score of 9.3 classifies this vulnerability as critical, indicating a high potential for impact. The vulnerability falls under the CWE-256 classification, which pertains to insecure storage of sensitive information. The publication date of this vulnerability is April 17, 2026.
Technical Analysis
The root cause of this vulnerability stems from the decision to store user passwords in plaintext. This approach fails to adhere to secure coding practices and leaves users vulnerable to credential theft. Attackers may leverage this vulnerability to gain unauthorized access to user accounts, potentially leading to further exploitation of sensitive data.
The attack vector is network-based, allowing remote attackers to exploit the vulnerability without needing physical access to the server. The attack complexity is low, meaning that it does not require advanced skills or resources to exploit. Additionally, no privileges are required, and user interaction is not necessary, making it easier for attackers to execute the exploit.
The vulnerability has a high confidentiality impact and integrity impact, as the compromise of plaintext passwords can lead to unauthorized access and data breaches. There is no availability impact, as the vulnerability does not affect the system's operational capabilities.
Risk & Impact Analysis
The risk posed by CVE-2025-15624 is substantial, especially given the critical CVSS score of 9.3. Organizations that have deployed Sparx Pro Cloud Server must be aware of the potential for significant data breaches due to the plaintext storage of passwords. The blast radius of this vulnerability is considerable, as it affects all users authenticated through OpenID.
The urgency assessment indicates that organizations should prioritize patching immediately. Failure to address this vulnerability can result in unauthorized access to sensitive user information, potentially leading to identity theft and other malicious activities. Organizations must implement remediation strategies to safeguard their systems and user data.
