CVE-2015-2425 Microsoft CVE debrief

CVE-2015-2425 is a Microsoft Internet Explorer memory corruption vulnerability that CISA includes in its Known Exploited Vulnerabilities catalog. That KEV listing means defenders should treat it as a real-world exploitation concern, not just a theoretical flaw. The safest response is to apply Microsoft updates and reduce or eliminate exposure to Internet Explorer-dependent systems.

Who should care

Security teams, Windows administrators, and asset owners who still have Internet Explorer installed, enabled, or required by legacy applications.

Technical summary

The supplied corpus identifies the flaw only as a memory corruption vulnerability in Microsoft Internet Explorer. CISA marks it as a known exploited vulnerability and directs defenders to apply updates per vendor instructions. The corpus does not provide a root-cause description, affected-version range, or exploit details, so remediation should focus on patching and exposure reduction rather than workaround tuning.

Defensive priority

High

Recommended defensive actions

  • Apply Microsoft updates and remediation guidance for Internet Explorer as soon as possible.
  • Inventory endpoints and servers that still use or depend on Internet Explorer.
  • Disable or remove Internet Explorer where business requirements allow.
  • Migrate legacy web applications to supported browsers or compatibility approaches that do not require Internet Explorer.
  • Use the CISA KEV due date in the supplied timeline as an urgency target for patch completion.
  • Verify patch status and confirm that no Internet Explorer-dependent systems remain unnecessarily exposed.

Evidence notes

Evidence is limited to the supplied CISA KEV record and the official links. The source item names the vulnerability as 'Microsoft Internet Explorer Memory Corruption Vulnerability,' marks it as a KEV entry, and states the required action: 'Apply updates per vendor instructions.' The supplied corpus does not include additional technical root-cause details or an affected-version list.
