CVE-2007-0210

Vulnerability

The Windows Image Acquisition (WIA) Service in Microsoft Windows XP Service Pack 2 contains an unchecked buffer vulnerability [1]. This is a buffer overflow condition that can be triggered when the service processes specially crafted input. The vulnerability only affects Windows XP SP2; other versions of Windows are not affected [1].

Exploitation

An attacker must have valid local logon credentials and be able to log on to the system [1]. The attacker then runs a specially crafted application that sends a malformed request to the WIA Service, triggering the buffer overflow. No user interaction is required beyond the attacker's own actions.

Impact

Successful exploitation allows the attacker to execute arbitrary code in the context of the WIA Service, which runs with SYSTEM privileges [1]. The attacker can then install programs, view/change/delete data, or create new accounts with full user rights, effectively taking complete control of the affected system [1].

Mitigation

Microsoft released security update MS07-007 on February 13, 2007, which addresses this vulnerability [1]. Customers should apply the update at the earliest opportunity. No workarounds are documented in the available references. Windows XP SP2 is the only affected version; users on other Windows versions are not impacted.
