CVE-2012-2539

Exploited

Microsoft Office - Word

Microsoft CVSS 7.8 Updated April 30, 2026

Executive Risk Summary

"A remote code execution vulnerability exists in Microsoft Word due to the way it handles crafted RTF data, allowing an attacker to execute arbitrary code or cause a denial of service. This vulnerability affects Microsoft Word 2003 SP3, 2007 SP2 and SP3, and 2010 SP1, as well as other related products."

Anticipated Attack Path

  1. 1. Initial Exploitation: Attacker sends crafted RTF data to the victim
  2. 2. Exploitation: Microsoft Word processes the crafted RTF data, leading to memory corruption
  3. 3. Post-Exploitation: Attacker gains control of the system, potentially leading to further malicious activity

Am I Vulnerable?

  • Verify that Microsoft Word is updated to the latest version
  • Check for any suspicious RTF files or attachments
  • Monitor system logs for signs of exploitation or memory corruption
