BleepingComputer reports.
Mitigations against the flaw have been applied for most of the potentially susceptible Microsoft Exchange Servers but 28,500 of the instances were confirmed to be vulnerable to the security issue, according to Shadowserver. The U.S. had the second-highest number of Microsoft Exchange Servers that could be impacted by the flaw after Germany, with the U.K., France, and Australia rounding out the five countries with the highest Exchange Server exposures. Active exploitation of CVE-2024-21410 has already prompted the Cybersecurity and Infrastructure Security Agency to order federal agencies to remediate the issue through updates, mitigations, or instance disconnections, by March 7.
