Attackers have posted public exploit code for a zero-day Windows vulnerability that could result in privilege escalation.

Soon after Microsoft announced its plans for next week's security update, the software giant disclosed that it was investigating public reports of a Windows privilege-elevation exploit.

The zero-day vulnerability, originally reported< in April, impacts Windows XP Professional Service Packs 2 and 3 and could allow users to escalate their privileges to "LocalSystem," according to an updated security advisory released Thursday. These accounts have unrestricted access to local resources.

A Microsoft representative, however, said there are no reports of in-the-wild attacks.

"At this time, we are not aware of attacks attempting to use this vulnerability," Bill Sisk, security response communications manager, wrote on a company blog. "We will continue to monitor the situation."

Users can safeguard themselves against the bug by applying the workarounds listed in the advisory, Sisk said.

A number of next week's scheduled patches will fix issues in Windows, but it is unclear if this particular vulnerability will be addressed.
