Summary
by MITRE • 08/20/2025
Synapse Mobility 8.0, 8.0.1, 8.0.2, 8.1, and 8.1.1 contain a privilege escalation vulnerability through external control of Web parameter. If exploited, a user of the product may escalate the privilege and access data that the user do not have permission to view by altering the parameters of the search function.

The vulnerability identified as CVE-2025-54551 affects Synapse Mobility versions 8.0 through 8.1.1, representing a critical privilege escalation flaw that stems from insufficient input validation and parameter handling within the web interface. This vulnerability falls under the category of insecure parameter handling, which is classified as CWE-20 in the Common Weakness Enumeration catalog. The flaw specifically manifests in the search function where external control of web parameters allows unauthorized users to manipulate the underlying system behavior through crafted input values.
The technical implementation of this vulnerability exploits the lack of proper access control checks within the application's parameter processing mechanism. When users interact with the search functionality, the system fails to adequately validate or sanitize the parameters passed to the backend services, enabling attackers to modify search criteria in ways that bypass normal authorization controls. This weakness creates a pathway where low-privilege users can potentially escalate their privileges and gain access to restricted data or functionality that should only be available to authorized personnel.
The operational impact of this vulnerability extends beyond simple unauthorized data access, as it fundamentally compromises the integrity of the application's security model. An attacker exploiting this flaw could potentially view sensitive information, modify data, or execute privileged operations without proper authentication or authorization. The vulnerability affects multiple versions of the Synapse Mobility platform, indicating a widespread issue that would require coordinated patching across various deployment environments. This type of vulnerability aligns with ATT&CK technique T1078.004, which covers legitimate credentials obtained through privilege escalation, and represents a significant risk to organizations relying on the platform for mobility management and security operations.
Mitigation strategies should focus on implementing robust input validation and parameter sanitization across all web-facing interfaces, particularly search and filtering functions. Organizations should deploy proper access control mechanisms that enforce authorization checks at every point of parameter processing, ensuring that user inputs cannot be used to manipulate system behavior beyond predefined boundaries. The implementation of proper session management and role-based access controls would significantly reduce the risk of privilege escalation. Additionally, regular security testing including parameter manipulation exercises and penetration testing should be conducted to identify similar vulnerabilities in the application's web interface components. System administrators should immediately apply vendor patches upon release and consider implementing web application firewalls to monitor and block suspicious parameter manipulation attempts.
