CVE-2025-15628 in Omada Access Points
Summary
by MITRE • 08/03/2026
Affected Omada devices rely on embedded certificates that are shared across deployments to establish trust between controllers and managed devices.
An attacker who obtains the embedded certificates may be able to impersonate trusted controllers or devices and intercept affected communications.

This vulnerability involves a critical flaw in Omada device security architecture where embedded certificates are statically distributed across multiple deployments rather than being individually provisioned. The shared certificate mechanism creates a single point of failure that fundamentally undermines the trust model between controllers and managed devices. When an attacker gains access to these embedded certificates, they can leverage them to establish fraudulent communication channels that appear legitimate to the network infrastructure.
The technical implementation flaw stems from poor certificate management practices where security credentials are not properly isolated or rotated per deployment. This design pattern violates fundamental security principles of isolation and unique credential provisioning. The embedded certificates typically contain identifying information such as serial numbers, device fingerprints, or controller identifiers that when compromised allow attackers to craft convincing impersonation attacks against the network authentication system.
From an operational perspective, this vulnerability creates significant risk for organizations using Omada management systems as it enables man-in-the-middle attacks and credential theft scenarios. Attackers can intercept and modify communications between controllers and devices, potentially gaining unauthorized access to device configurations, monitoring network traffic, or executing malicious commands through the compromised trust relationships. The impact extends beyond individual device compromise to potential network-wide infiltration since the same certificates may be used across multiple managed environments.
The vulnerability aligns with CWE-310 - Cryptographic Issues and specifically relates to CWE-326 - Inadequate Encryption Strength and CWE-327 - Use of a Broken or Risky Cryptographic Algorithm. From an ATT&CK framework perspective, this represents a privilege escalation vector through credential access and defense evasion techniques that allow attackers to maintain persistent access while remaining undetected by normal security monitoring systems.
Organizations should implement immediate mitigations including certificate rotation procedures, deployment-specific credential provisioning, and network segmentation to limit the impact of compromised certificates. Regular security audits should verify certificate uniqueness across deployments and establish automated monitoring for unauthorized certificate usage patterns. The long-term solution requires implementing proper certificate lifecycle management with unique provisioning per device or deployment rather than relying on shared embedded credentials.
