Despite previously claiming the DogWalk vulnerability did not constitute a security issue, Microsoft has now released a patch to stop attackers from actively exploiting the vulnerability. Credit: Magdalena Petrova Microsoft has confirmed that a high-severity, zero-day security vulnerability is actively being exploited by threat actors and is advising all Windows and Windows Server users to apply its latest monthly Patch Tuesday update as soon as possible. The vulnerability, known as CVE-2022-34713 or DogWalk, allows attackers to exploit a weakness in the Windows Microsoft Support Diagnostic Tool (MSDT). By using social engineering or phishing, attackers can trick users into visiting a fake website or opening a malicious document or file and ultimately gain remote code execution on compromised systems. DogWalk affects all Windows versions under support, including the latest client and server releases, Windows 11 and Windows Server 2022. The vulnerability was first reported in January 2020 but at the time, Microsoft said it didn’t consider the exploit to be a security issue. This is the second time in recent months that Microsoft has been forced to change its position on a known exploit, having initially rejected reports that another Windows MSDT zero-day, known as Follina, posed a security threat. A patch for that exploit was released in June’s Patch Tuesday update. Charl van der Walt, head of security research at Orange Cyberdefense, said that although Microsoft could perhaps be criticised for failing to consider how frequently and easily files with apparently innocent extensions are used to deliver malicious payloads, also noted that with several thousand vulnerabilities reported each year, it’s to be expected that Microsoft’s risk-based triage approach to assessing vulnerabilities won’t be infallible. “If everything is urgent, then nothing is urgent,” he said. “The security community has long stopped believing vulnerabilities and threats will be eradicated any time soon, so the challenge now becomes the development of a kind of agility that can perceive changes in the threat landscape and adapt accordingly.” Related content news analysis Workers with AI skills are getting these pay cash premiums As AI deployments become more critical to digital transformation projects, organizations are struggling to find skilled workers to support the new technology, so they're paying premiums for prospective hires or current employees who obtain the n By Lucas Mearian 01 May 2024 7 mins Generative AI IT Jobs IT Skills news Atlassian Rovo brings AI smarts to enterprise search With Rovo, the company looks to expand existing search capabilities in its products, tapping into documents held in third-party apps and using generative AI to provide a natural language interface.
