CVE-2025-45081 is a vulnerability identified in IITB SSO version 1.1.0, which arises from misconfigured settings within the single sign-on (SSO) system. The vulnerability allows attackers to gain unauthorized access to sensitive application data. Although specific technical details such as the exact misconfiguration or attack vector are not provided, the nature of the vulnerability suggests that improper configuration of authentication or authorization controls in the SSO system could permit attackers to bypass security mechanisms. This could lead to exposure of confidential information or unauthorized data access within applications relying on IITB SSO for identity management. The absence of a CVSS score and lack of known exploits in the wild indicate that the vulnerability is newly published and may not yet be widely exploited. However, because SSO systems are critical components in enterprise identity and access management, any misconfiguration can have significant security implications. The vulnerability was reserved in April 2025 and published in July 2025, indicating recent discovery and disclosure. No patches or mitigation links are currently available, which suggests that affected organizations need to proactively review and correct their SSO configurations to prevent exploitation.

For European organizations, the impact of this vulnerability could be substantial, especially for those relying on IITB SSO v1.1.0 for centralized authentication across multiple applications. Unauthorized access to sensitive application data can lead to data breaches, loss of confidentiality, and potential regulatory non-compliance under GDPR. The compromise of SSO systems can also facilitate lateral movement within networks, increasing the risk of further exploitation and data exfiltration. Organizations in sectors with high-value data such as finance, healthcare, and government are particularly at risk. Additionally, the centralized nature of SSO means that a single misconfiguration can affect multiple applications and services, amplifying the potential damage. The lack of known exploits in the wild provides a window for mitigation, but the risk remains high if attackers discover and exploit the misconfiguration before organizations remediate it.

European organizations using IITB SSO v1.1.0 should immediately conduct a thorough audit of their SSO configurations to identify and correct any misconfigurations. This includes verifying authentication and authorization policies, ensuring least privilege access, and validating session management settings. Organizations should implement strict access controls and monitor authentication logs for unusual activity indicative of exploitation attempts. Since no patches are currently available, organizations should consider isolating or limiting the use of IITB SSO until a fix is released. Employing multi-factor authentication (MFA) at the application level can provide an additional security layer. Furthermore, organizations should engage with the vendor or community maintaining IITB SSO to obtain updates or guidance. Regular security assessments and penetration testing focused on SSO components are recommended to detect similar vulnerabilities proactively.
