CVE-2010-0249 is a significant historical vulnerability in Microsoft Internet Explorer, most famously known for its role in the "Operation Aurora" cyberattacks.

Overview and Impact
  • Vulnerability Type: It is a use-after-free memory corruption vulnerability in the way Internet Explorer handles HTML objects [1]?id=CVE-2010-0249?kagi_q=CVE-2010-0249+details+exploitation+threat+actors.
  • Impact: Successful exploitation allows a remote attacker to execute arbitrary code on the victim's system with the privileges of the current user [1].
Exploitation and Usage
  • Active Exploitation: The vulnerability was actively exploited in the wild, most notably as part of Operation Aurora, a highly sophisticated, targeted cyberattack campaign that began in late 2009 and was publicly disclosed by Google in early 2010 [2].
  • Attack Method: It is a remote attack vector. Exploitation typically requires a user to visit a specially crafted malicious website using an affected version of Internet Explorer.
  • Targeted Attacks: This vulnerability was central to targeted attacks against major corporations and organizations, rather than broad, indiscriminate ransomware campaigns. It was used to gain unauthorized access to sensitive corporate networks and intellectual property.
  • Proof-of-Concept/Exploit Availability: Public exploit code became available shortly after the vulnerability was disclosed, which significantly increased the risk of exploitation by various threat actors [2].
Affected Products and Mitigation
  • Affected Versions: The vulnerability affected Microsoft Internet Explorer 6, 7, and 8 across a wide range of Windows operating systems, including Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, and Windows 7 [1].
  • Status: Microsoft addressed this vulnerability in January 2010 via security updates (specifically Security Advisory 979352) [3]. Given the age of the vulnerability, all modern systems are long since patched, though it remains a notable entry in the history of targeted cyber espionage.
