CVE-2026-1433 in uniFLOW ULM Standalone
Summary
by MITRE • 07/06/2026
uniFLOW Universal Login Manager (ULM) Standalone contains an information disclosure vulnerability that may allow an authenticated administrator to access sensitive configuration information through the ULM Remote User Interface (RUI). Exploitation requires administrative privileges and may disclose configuration data associated with SMTP or LDAP integrations. ULM deployments connected to uniFLOW Server or uniFLOW Online are not affected.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The uniFLOW Universal Login Manager represents a critical information disclosure vulnerability within its standalone deployment mode that specifically targets the Remote User Interface component. This flaw exists as a direct result of insufficient access controls and data protection mechanisms within the authentication framework, allowing authenticated administrative users to gain unauthorized access to sensitive configuration parameters through the RUI interface. The vulnerability stems from improper privilege escalation handling where administrative credentials, while required for exploitation, do not properly restrict access to configuration data that should remain protected. This represents a clear violation of the principle of least privilege and demonstrates inadequate separation of concerns within the application's security architecture.
The technical implementation of this vulnerability manifests through the RUI interface which fails to properly validate administrative access levels when retrieving configuration information. When an authenticated administrator interacts with specific API endpoints or interface components, the system does not adequately verify that the requesting user has appropriate authorization levels to view sensitive integration parameters such as SMTP server configurations or LDAP directory service credentials. This weakness creates a path where administrative users can potentially extract configuration data that may include authentication tokens, connection strings, and credential information for external services that the uniFLOW system integrates with. The vulnerability is specifically rooted in the application's failure to implement proper access control checks at the data retrieval layer.
The operational impact of this information disclosure vulnerability extends beyond simple data exposure, as it provides potential attackers with detailed configuration information that could facilitate further exploitation attempts. When administrators have access to SMTP integration settings, they may discover email server configurations that could be used for phishing attacks or credential harvesting. Similarly, LDAP integration details might reveal directory service structures, user naming conventions, and authentication mechanisms that could aid in lateral movement within network environments. The disclosure of such sensitive information creates opportunities for attackers to escalate privileges, conduct social engineering campaigns, or establish persistence through compromised credentials. This vulnerability directly relates to CWE-200 which addresses information exposure and aligns with ATT&CK technique T1552 for credentials in files and T1078 for valid accounts.
Organizations utilizing the standalone version of uniFLOW Universal Login Manager must implement immediate mitigations to address this vulnerability, including enforcing strict access controls on administrative interfaces and implementing network segmentation to limit exposure. The recommended approach involves applying the vendor-provided security patches or updates that address the specific access control flaw, while also implementing monitoring solutions to detect unauthorized access attempts to configuration data. Additionally, organizations should conduct comprehensive privilege reviews to ensure that administrative accounts have only the minimum necessary access rights and implement regular audits of configuration data access logs. The absence of this vulnerability in uniFLOW Server or uniFLOW Online deployments indicates that the issue is specific to the standalone implementation, suggesting that organizations should consider migrating to supported deployment models where possible.
This vulnerability highlights the importance of proper application security design and the need for comprehensive security testing throughout the software development lifecycle. The flaw demonstrates how seemingly minor access control oversights can create significant security risks when combined with administrative privileges. Organizations should also implement defense-in-depth strategies including network monitoring, intrusion detection systems, and regular security assessments to identify similar vulnerabilities across their infrastructure. The information disclosure nature of this vulnerability underscores the need for organizations to maintain comprehensive incident response procedures that can quickly address unauthorized access to sensitive configuration data, particularly in environments where administrative access is required for system maintenance operations.
