Analyst readout for executives and security teams
Plain-English summary
This is an old Microsoft Internet Explorer scripting-engine flaw. A malicious website could trigger memory corruption in VBScript or JScript and potentially run code on the visitor’s system, or crash the browser. Business risk is mainly from legacy Internet Explorer 8 through 11 still used for internal applications or unmanaged endpoints.
Executive priority
Prioritize remediation if legacy Internet Explorer remains in use. For organizations without IE 8 through 11 exposure, this is mainly a historical hygiene and asset-validation item.
Technical view
CVE-2015-6089 affects Microsoft VBScript and JScript engines as used by Internet Explorer 8 through 11. The CVE describes remote arbitrary code execution or denial of service through memory corruption caused by a crafted website. The provided bundle does not include CVSS, CWE, detailed prerequisites, or confirmed exploit telemetry.
Likely exposure
Exposure is likely limited to environments where Internet Explorer 8 through 11 remains installed, usable, or required for legacy workflows. Highest concern is endpoints that can browse untrusted sites or open web content in IE-compatible contexts.
Exploitation context
The cited CVE states remote attackers can use a crafted website. The bundle does not show CISA KEV listing or another cited source confirming active exploitation. Treat exploitation status as unconfirmed, not absent.
Researcher notes
The source bundle is sparse: no CVSS vector, CWE, patch KB details, or exploit evidence are included. Analysis should stay anchored to Microsoft MS15-112 and the CVE description, with validation focused on legacy browser presence and patch state.
Mitigation direction
- Review and apply Microsoft MS15-112 guidance for affected systems.
- Confirm relevant Internet Explorer and scripting engine updates are installed.
- Retire Internet Explorer 8 through 11 dependencies where feasible.
- Restrict legacy IE use to trusted internal sites only where removal is not immediate.
- Monitor vendor guidance for any environment-specific remediation details.
Validation and detection
- Inventory endpoints with Internet Explorer 8 through 11 present or enabled.
- Check patch compliance against Microsoft MS15-112 requirements.
- Review proxy or endpoint telemetry for legacy IE web browsing.
- Identify applications that still require VBScript, JScript, or IE compatibility.
- Confirm compensating controls for any systems that cannot be patched.
