REPAIR MICROSOFT OUTLOOK 2016 ON WINDOWS 10 PATCH
Microsoft is recommending organizations fix both that vulnerability – a patch was issued as part of Patch Tuesday this week – as well as the earlier CVE-2023-23397.īarnea wrote that he hoped Microsoft will remove the custom reminder sound feature, saying it poses more security risks than any potential value to users. The flaw, CVE-2023-29324, has a CVSS severity score of 6.5. … We believe this kind of confusion can potentially cause vulnerabilities in other programs that use MapUrlToZone on a user-controlled path and then use a file operation (such as CreateFile or a similar API) on the same path." He added that the problem appears to be the "result of the complex handling of paths in Windows. It is a zero-click vulnerability, meaning it can be triggered with no user interaction." "An unauthenticated attacker on the internet could use the vulnerability to coerce an Outlook client to connect to an attacker-controlled server," Barnea wrote. And it could be done with a single keystroke, adding a second '\' to the universal naming convention (UNC) path. To find a bypass for Microsoft's original patch, Barnea wanted to craft a path that MapUrlToZone would label as local, intranet, or a trusted zone – meaning Outlook could safely follow it – but when passed to the CreateFile function to open, would make the OS go connect to a remote server.Įventually he found that miscreants could change the URL in reminder messages, which duped MapUrlToZone checks into seeing remote paths as local ones.

The cyber-gang used it in attacks against organizations in European governments as well as transportation, energy, and military spaces. That flaw was bad enough to earn a CVSS severity rating of 9.8 out of 10 and had been exploited by a Russia-linked crew for about a year by the time the fix was issued in March. "As part of the connection to the remote SMB server, the Net-NTLMv2 hash is sent in a negotiation message." "An attacker can specify a UNC path that would cause the client to retrieve the sound file from any SMB server," he explained. According to Barnea, emails can contain a reminder that includes a custom notification sound specified as a path using an extended MAPI property using PidLidReminderFileParameter.
