Microsoft Internet Explorer Peer Objects Use-After-Free RCE

IdentifiersCVE-2010-0806CWE-416· Use After Free

CVE-2010-0806 is a use-after-free vulnerability in the Peer Objects component (iepeers.dll) of Microsoft Internet Explorer 6, 6 SP1, and 7. The flaw occurs when Internet Explorer accesses an invalid pointer after an object has been deleted, resulting in memory corruption. A remote attacker can trigger the condition using specially crafted web content, including malicious HTML and script, causing the browser to dereference freed memory. The vulnerability was exploited in the wild in March 2010 and has also been referred to as an uninitialized memory corruption issue in public reporting.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can lead to arbitrary code execution in the security context of the current user. In practical terms, this allows an attacker to run attacker-controlled code when a victim visits a malicious webpage or otherwise renders crafted web content in a vulnerable Internet Explorer instance. Depending on the victim's privileges, this can result in full compromise of the affected workstation, malware installation, data theft, and follow-on intrusion activity.

Mitigation

If you can’t patch tonight, do this now.

Until remediation is completed, reduce exposure by preventing use of vulnerable Internet Explorer versions, especially for untrusted or internet-facing browsing. Restrict or disable access to malicious or untrusted web content through network and web filtering controls, and limit user privileges to reduce post-exploitation impact. Where operationally feasible, isolate or decommission legacy systems that still require affected IE versions.

Remediation

Patch, then assume compromise.

Apply Microsoft's security update for CVE-2010-0806 on affected Internet Explorer installations. Because the affected products are legacy Internet Explorer versions (IE 6, 6 SP1, and 7), organizations should upgrade to supported software where possible and retire unsupported browsers. If the affected Internet Explorer version is end-of-life or end-of-service and no supported patch path remains in the environment, discontinue use of the vulnerable product.
