Severity
Summary
The (1) JScript 5.8 and (2) VBScript 5.8 scripting engines in Microsoft Windows Server 2008 R2 and Windows 7 do not properly load decoded scripts obtained from web pages, which allows remote attackers to trigger memory corruption and consequently obtain sensitive information via a crafted web site, aka "Scripting Engines Information Disclosure Vulnerability."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
