The Symmetricom s350i time synchronization device running firmware version 2.70.15 contains a privilege escalation vulnerability that affects remote authenticated users. This vulnerability stems from improper session management and access control mechanisms within the device's web interface authentication system. The flaw allows an attacker who has already established an authenticated session to manipulate the application's behavior and elevate their privileges without additional authorization checks.
The technical implementation of this vulnerability involves the device's authentication subsystem failing to properly validate user permissions when redirecting unauthenticated users to the login page. When an authenticated user interacts with certain application components, the system incorrectly processes session state information and redirects the user to the login interface while simultaneously maintaining elevated privileges. This creates a condition where the authentication context becomes corrupted and allows privilege escalation through manipulation of the login redirection flow.
The operational impact of this vulnerability extends beyond simple privilege escalation as it represents a fundamental flaw in the device's access control model. An attacker with basic authentication credentials can leverage this weakness to gain administrative privileges on the time synchronization device, potentially compromising the entire network time synchronization infrastructure. This is particularly concerning in enterprise environments where precise timekeeping is critical for security operations, log correlation, and compliance requirements.
The vulnerability aligns with CWE-285, which addresses improper authorization in authentication systems, and demonstrates characteristics consistent with ATT&CK technique T1078 for valid accounts and T1548 for abuse of privileges. Organizations using Symmetricom s350i devices should implement immediate mitigations including firmware updates to versions that address this privilege escalation flaw, network segmentation to limit access to these devices, and monitoring for suspicious authentication patterns. Additionally, administrators should enforce strict access controls and regularly audit user permissions to prevent exploitation of this vulnerability. The device manufacturer should be consulted for specific patch information and recommended remediation procedures to ensure complete protection against this and similar privilege escalation threats.
