Privilege Escalation in Oracle Solaris Availability Suite Service

IdentifiersCVE-2018-2892CWE-195

CVE-2018-2892 is a local privilege escalation vulnerability in the Availability Suite Service kernel component of Oracle Solaris 10 and 11.3. The flaw is caused by a signedness error in bounds checking when handling the SDBC_TEST_INIT ioctl in the /dev/sdbc device path. A low-privileged local user can trigger the bug to perform an arbitrary kernel-mode memory write, leading to ring0 code execution and full compromise of the affected Solaris host.

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 allows a local attacker with low privileges to overwrite kernel memory, execute arbitrary code in kernel context, and take over the affected Solaris system. The resulting impact includes complete compromise of confidentiality, integrity, and availability.

Mitigation

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

Restrict local shell and logon access to trusted users only, minimize the number of accounts with access to affected Solaris systems, and limit access to the vulnerable device interface to the extent operationally possible until patches are applied. Because exploitation is local and requires logon access, strong account management and least-privilege controls reduce exposure but do not replace patching.

Remediation

Patch, then assume compromise.

Apply Oracle's July 2018 Critical Patch Update for Solaris 11.3. For Solaris 10, obtain and apply the relevant fixes made available through Oracle extended support. Upgrading to a supported and fully patched release is recommended where possible.
