Detailsinfo

A vulnerability, which was classified as very critical, was found in Microsoft Internet Explorer up to 6 SP1 (Web Browser). This affects an unknown functionality. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Microsoft Internet Explorer 5.01 SP4 and 6 SP1; Internet Explorer 6 for Windows XP SP2 and SP3 and Server 2003 SP2; and Internet Explorer 7 and 8 for Windows XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 do not properly handle attempts to access deleted objects in memory, which allows remote attackers to execute arbitrary code via an HTML document containing embedded style sheets that modify unspecified rule properties that cause the behavior element to be "improperly processed," aka "Uninitialized Memory Corruption Vulnerability."

The weakness was disclosed 07/29/2009 (Website). The advisory is shared at us-cert.gov. This vulnerability is uniquely identified as CVE-2009-1919. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/09/2025). It is expected to see the exploit prices for this product decreasing in the near future.MITRE ATT&CK project uses the attack technique T1059 for this issue.
