CVE-2008-4844

Status: ModifiedHigh (9.3)—💥 Exploit

Use-after-free vulnerability in the CRecordInstance::TransferToDestination function in mshtml.dll in Microsoft Internet Explorer 5.01, 6, 6 SP1, and 7 allows remote attackers to execute arbitrary code via DSO bindings involving (1) an XML Island, (2) XML DSOs, or (3) Tabular Data Control (TDC) in a crafted HTML or XML document, as demonstrated by nested SPAN or MARQUEE elements, and exploited in the wild in December 2008.

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
Base score: 9.3

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 67%
Percentile among all scored CVEs: 99
Score date: 10/8/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
