CVE-2010-0806

Exploited

Microsoft Internet Explorer - Peer Objects component (iepeers.dll)

Microsoft CVSS 8.8 Updated May 29, 2026

Executive Risk Summary

"A use-after-free vulnerability in the Peer Objects component of Microsoft Internet Explorer allows remote attackers to execute arbitrary code via vectors involving access to an invalid pointer after the deletion of an object. This vulnerability can be exploited by an attacker to gain control of a vulnerable system, potentially leading to data breaches, malware infections, and other security threats."

Anticipated Attack Path

  1. 1. Initial Exploitation: Attacker sends a malicious request to the vulnerable Internet Explorer instance
  2. 2. Post-Exploitation: Attacker gains control of the system and potentially installs malware or steals sensitive data
  3. 3. Lateral Movement: Attacker uses the compromised system as a pivot point to attack other systems on the network

Am I Vulnerable?

  • Verify that Microsoft Internet Explorer is up-to-date with the latest security patches
  • Implement a web application firewall (WAF) to detect and block malicious traffic
  • Use an alternative web browser that is not vulnerable to this exploit
