Oracle Solaris Remote Administration Daemon unauthenticated HTTPS compromise

IdentifiersCVE-2026-46978

CVE-2026-46978 is a vulnerability in the Oracle Solaris Remote Administration Daemon affecting supported Oracle Solaris 11.4 systems. According to the provided advisory content, the flaw is remotely exploitable over HTTPS by an unauthenticated attacker with network access. Oracle rates it CVSS 3.1 10.0 with vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N, indicating low attack complexity, no privileges required, no user interaction, and scope change. The specific vulnerable function or code path is not identified in the provided material, but successful exploitation allows compromise of Oracle Solaris and may significantly impact additional products due to scope change.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in unauthorized creation, deletion, or modification of critical data or all data accessible to Oracle Solaris, as well as unauthorized access to critical data or complete access to all Oracle Solaris-accessible data. Oracle notes that attacks may significantly impact additional products because the vulnerability has scope change. The provided CVSS information indicates severe confidentiality and integrity impact, with no stated availability impact.

Mitigation

If you can’t patch tonight, do this now.

Until the patch can be applied, reduce exposure by restricting or blocking network access to the affected Remote Administration Daemon over HTTPS to trusted management networks only, and remove unnecessary privileges or access to affected packages from users who do not require them. Oracle notes that blocking required network protocols or removing access may affect functionality and should be tested before production deployment; these are temporary risk-reduction measures, not long-term fixes.

Remediation

Patch, then assume compromise.

Apply Oracle's June 2026 Critical Patch Update for Oracle Solaris. The provided content states the fix for this issue is included in Solaris 11.4 SRU93. Oracle also recommends remaining on actively supported versions so security patches are available.
