Word Unspecified Exploit(3)
A remote code execution vulnerability exists within Microsoft Word 2000 which may allow for a remote attacker to execute arbitrary code under the context of the logged in user. This vulnerability requires user interaction. In a web-based scenario (e-mail, Web site), a user would still have to open a file manually, as it would not be auto-opened.
This is reported by Symantec as a different vulnerability than eEye ZDT: Word Unspecified Exploit and eEye ZDT: Word Unspecified Exploit(2).
NOTE: This information is gathered from the reference below. eEye Research is currently researching the cause of the vulnerability and will update this ZDT entry as more information becomes available.
Arbitrary code execution under the context of the logged in user. Public exploit drops backdoor onto exploited systems, allowing for remote access by the attacker.
This client-side file-format vulnerability has high impact potential for targeted attacks against networks. These attacks could be used to gain sensitive information, install botnet software, as well as many other common exploitations. Although Word files are not auto-opened by most web browsers and e-mail clients, the severity of this vulnerability should not be overlooked.
Currently there is no known mitigation for this vulnerability.
