vbscript.dll in Microsoft VBScript 5.6 through 5.8, as used with Internet Explorer 6 through 11 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "VBScript Memory Corruption Vulnerability."

Security readout for executives and security teams

Plain-English summary

This is an old Microsoft VBScript memory corruption flaw used through Internet Explorer 6 through 11. A malicious website could make vulnerable systems run attacker-controlled code or crash. Business urgency depends on whether any legacy Windows or Internet Explorer workflows remain in use.

Executive priority

Treat this as a legacy-browser risk that matters most where old Windows or Internet Explorer dependencies persist. Prioritize patch verification and retirement of VBScript/IE paths over broad emergency response unless exposure is confirmed.

Technical view

CVE-2014-6363 affects vbscript.dll in Microsoft VBScript 5.6 through 5.8, as used with Internet Explorer 6 through 11 and other products. The source describes remote code execution or denial of service via crafted web content. Public exploit material is referenced, but active exploitation is not established by the supplied sources.

Likely exposure

Exposure is most plausible on legacy Windows endpoints or applications that still use Internet Explorer, embedded IE controls, or VBScript execution paths. Modern environments without IE/VBScript dependency are likely lower risk, but the bundle lacks detailed CPEs.

Exploitation context

The CVE description requires a crafted website and a vulnerable VBScript/Internet Explorer path. Exploit-DB is cited, indicating public exploit material exists. The source bundle marks KEV as false, so active exploitation should not be claimed from this evidence.

Researcher notes

The bundle lacks CVSS, CWE, and precise affected CPEs, so asset validation is important. The key technical facts are vbscript.dll memory corruption, IE 6 through 11 usage, crafted web content, and potential code execution or denial of service.

Mitigation direction

  • Apply the Microsoft updates referenced by MS14-080 and MS14-084 where applicable.
  • Retire Internet Explorer and VBScript-dependent workflows where business feasible.
  • Restrict VBScript or Active Scripting in legacy Internet Explorer zones per Microsoft guidance.
  • Isolate legacy systems that cannot be updated or decommissioned promptly.
  • Check current vendor guidance for supported compensating controls.

Validation and detection

  • Inventory endpoints and applications using Internet Explorer 6 through 11 or VBScript 5.6 through 5.8.
  • Verify applicable Microsoft security updates from MS14-080 and MS14-084 are installed.
  • Review vulnerability scanner findings for CVE-2014-6363 on legacy Windows assets.
  • Confirm embedded browser controls do not rely on vulnerable VBScript execution paths.
  • Document any exceptions with owner, business justification, and isolation controls.
