Critical Unauthenticated RCE Vulnerability in Oracle Solaris: CVE-2026-46978 Exposes Enterprise Data to Remote Attacks
Overview
CVE-2026-46978 is a critical remote code execution vulnerability in Oracle Solaris Remote Administration Daemon. Exploitation requires no authentication and enables full data compromise, posing immediate risk to systems leveraging Solaris 11.4 without mitigation.
Technical Analysis
The vulnerability resides in the Remote Administration Daemon's handling of HTTPS requests, allowing attackers to craft malicious payloads that bypass authentication and execute arbitrary operations. Its CVSS score of 10.0 reflects trivial exploitability (AV:N/AC:L) with unauthenticated access, enabling complete data modification and exfiltration. The 'scope change' (S:C) in the vector indicates potential cascading effects on interconnected systems and components beyond Solaris itself.
Enterprise & DIB Impact
Defense Industrial Base contractors and enterprises relying on Oracle Solaris for mission-critical infrastructure face acute risk. Attackers could disrupt operations, compromise sensitive datasets, or establish persistent access, with potential cascading impacts on interdependent systems. Legacy systems often remain vulnerable due to delayed patch cycles.
Recommended Actions
- Patch Oracle Solaris 11.4 immediately using official errata
- restrict network access to the Remote Administration Daemon via firewalls
- monitor HTTPS traffic for anomalous requests to RAD endpoints
- disable RAD services where not operationally required
- and apply the principle of least privilege to remaining administrative interfaces.
