Microsoft Strengthens Security Against Attacks on Power Pages and Bing

Microsoft has announced that it has successfully fortified its services against recent cyberattacks targeting websites created using its Power Pages platform. Additionally, vulnerabilities within the Bing search engine have been addressed to prevent potential exploitation.

Security experts revealed that attackers had attempted to breach websites developed on the Microsoft Power Pages platform. These attacks were particularly concerning because they could have exploited a weakness within Bing to introduce malicious code.

In response to these threats, Microsoft has implemented automatic patches, meaning that administrators will not need to manually install security updates for these services. In an official statement regarding Power Pages, Microsoft indicated that attackers had previously been able to bypass authentication mechanisms, thereby gaining unauthorized access to certain websites (identified as CVE-2025-24989, categorized as 'high' severity). However, this vulnerability has now been resolved, and Microsoft has reached out to affected customers with guidance on necessary actions.

The extent of the attacks on Power Pages remains unclear, with no specific details released regarding the number of sites impacted or the duration of the breaches. Furthermore, Microsoft addressed vulnerabilities within Bing, where attackers could have leveraged a lack of authentication in a critical function to execute malicious code via network access (CVE-2025-21355, also rated as 'high' severity). Fortunately, there have been no reports indicating that these vulnerabilities were actively exploited.

As part of its ongoing commitment to security, Microsoft continues to monitor its services closely and ensure that robust measures are in place to protect users from cyber threats. The company emphasizes the importance of vigilance in the face of evolving security challenges and encourages all users to stay informed about the latest developments and best practices for maintaining online security.

In conclusion, the swift response from Microsoft to these threats highlights the importance of continuous security enhancements in the digital landscape. Users of Power Pages and Bing can now operate with increased confidence, knowing that potential vulnerabilities have been addressed effectively.
