CVE-2025-15622 identifies an insufficiently protected credentials vulnerability in Sparx Systems Pty Ltd. Sparx Enterprise Architect. This vulnerability allows a desktop client to reveal plaintext OAuth2 client secrets. The client decodes the secret and uses it to exchange for access and ID tokens as part of the OpenID authentication flow.
With a CVSS score of 6.2, this vulnerability is classified as medium severity, indicating a potential for moderate impact should it be exploited. The presence of plaintext secrets significantly increases the risk of unauthorized access to sensitive resources.
Risk to organizations includes potential exposure of sensitive credentials, leading to unauthorized access and compromise of systems. Organizations using Sparx Enterprise Architect should assess their exposure to this vulnerability and take necessary precautions.
Currently, there are no known exploits or public proof-of-concept (PoC) code associated with this vulnerability. However, given the nature of the issue, organizations should prioritize patching when updates become available.
Vulnerability Details
The official CVE description highlights the insufficiency in protecting credentials, particularly the plaintext OAuth2 client secret. This vulnerability falls under the Common Weakness Enumeration (CWE) classification of CWE-522.
The CVSS score of 6.2 reflects the attack vector as local, with low complexity and no privileges required for an attacker to exploit this vulnerability. The confidentiality impact is rated low, while the integrity impact also holds a low rating, indicating a limited potential for data alteration.
Technical Analysis
The root cause of this vulnerability stems from the improper storage of sensitive credentials. The desktop client’s ability to reveal plaintext OAuth2 client secrets presents a significant security risk. Attackers may leverage this flaw to gain unauthorized access to sensitive resources using the decoded secrets.
The attack vector is local, meaning that a user with access to the client could potentially exploit the vulnerability. The attack complexity is low, indicating that an attacker does not require advanced skills or knowledge to exploit this vulnerability. There is no user interaction required, which further enhances the risk.
The confidentiality impact is rated low, as the exposure of OAuth2 client secrets can lead to unauthorized access but does not guarantee complete system compromise. The integrity and availability impacts are also rated low and none, respectively.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is notable. Organizations using Sparx Enterprise Architect need to understand that the exposure of plaintext credentials can facilitate unauthorized access and compromise sensitive data.
Given that this vulnerability is currently classified as medium severity, organizations should address it during their priority patch cycle. The potential blast radius of exploitation includes any systems relying on the affected OAuth2 client for authentication.
Organizations should prioritize remediation efforts to mitigate this vulnerability before it can be exploited. Prompt patching and review of access controls can significantly reduce the risk of unauthorized access.
