CVE-2025-0663: A cross-tenant authentication vulnerability exists in multiple WSO2 products due to improper cryptographic design in Adaptive Authentication. A single cryptographic key is used across all tenants to sign authentication cookies, allowing a privileged user in one tenant to forge authentication cookies for users in other tenants. Because the Auto-Login feature is enabled by default, this flaw may allow an attacker to gain unauthorized access and potentially take over accounts in other tenants. Successful exploitation requires access to Adaptive Authentication functionality, which is typically restricted to high-privileged users. The vulnerability is only exploitable when Auto-Login is enabled, reducing its practical impact in deployments where the feature is disabled.
The exploitability of CVE-2025-0663 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
The exploitability of CVE-2025-0663 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-0663, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-0663, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
