Emphasismine

IdentifiersCVE-2017-1274CWE-121

Emphasismine is a stack-based buffer overflow vulnerability in the IMAP service of IBM Domino 8.5.3 and 9.0. The flaw is triggered in processing of the IMAP EXAMINE command when an authenticated user supplies an excessively large mailbox name, causing memory corruption on the stack. Successful exploitation can allow arbitrary code execution in the context of the Domino server process.

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 remote authenticated attacker to execute arbitrary code with the privileges of the Domino server IMAP service. Depending on the server's privilege level and deployment, this can result in full compromise of the affected host, unauthorized access to mail data, service disruption, and follow-on activity such as persistence or lateral movement.

Mitigation

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

Apply the vendor-provided fix as the primary mitigation. Where immediate patching is not possible, disable IMAP services to remove the exposed attack surface. On Windows deployments, exploit-mitigation tooling such as Microsoft EMET may provide temporary hardening against exploitation attempts.

Remediation

Patch, then assume compromise.

Upgrade affected systems to a fixed release. Vendor guidance identifies Domino 9.0.1 Feature Pack 8 Interim Fix 2 and Domino 8.5.3 Fix Pack 6 Interim Fix 17 as remediated versions. For environments that must remain on older supported releases, obtain a vendor-supported custom hotfix through support channels.
