CVE-2025-15629: CWE-331 Insufficient entropy in TP-Link Systems Inc. Omada Gateways
A cryptographic weakness exists in the Omada adoption protocol where session encryption keys used to protect communications between controllers and managed devices may be predictable due to insufficient entropy in session key generation. An attacker who successfully intercepts adoption-related communications may be able to recover session encryption keys and decrypt affected communications.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-15629) involves insufficient entropy in the session key generation process used by the Omada adoption protocol in TP-Link Omada Gateways. Due to predictable session encryption keys, an attacker intercepting adoption-related communications could potentially recover these keys and decrypt sensitive communications between controllers and managed devices. The CVSS 4.0 base score is 6.9, indicating a medium severity. No vendor advisory or patch information is currently available, and no known exploits are reported in the wild.
Potential Impact
An attacker capable of intercepting adoption-related communications may recover session encryption keys and decrypt the protected communications, potentially exposing sensitive data exchanged between controllers and managed devices. This compromises the confidentiality of the adoption protocol communications but does not indicate privilege escalation or integrity impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or workaround is currently documented, monitor TP-Link's advisories for updates. Avoid intercepting or exposing adoption-related communications to untrusted networks to reduce risk until a fix is available.
