Signature Detail

HTTP: Microsoft Excel Malformed Selection Record Remote Code Execution

This signature detects attempts to exploit a known issue with Microsoft Excel. A successful attack can lead to arbitrary code execution.

Extended Description

Microsoft Excel is prone to a remote code-execution vulnerability. Successfully exploiting this issue allows attackers to corrupt process memory and to execute arbitrary code in the context of targeted users. Note that Microsoft Office applications include functionality to embed Office files as objects contained in other Office files. As an example, Microsoft Word files may contain embedded malicious Microsoft Excel files, making Word documents another possible attack vector.
