Microsoft’s May Patch Tuesday release has addressed several critical vulnerabilities in SharePoint and Qakbot, a popular enterprise collaboration platform. The company has issued patches for two severe flaws in SharePoint, which could have allowed attackers to take control of an affected system or steal sensitive data.

The first vulnerability, tracked as CVE-2023-2342, affects SharePoint Enterprise and SharePoint Foundation. It is caused by a weakness in the way SharePoint handles user authentication, allowing an attacker to impersonate a legitimate user and gain unauthorized access to sensitive data or perform malicious actions.

An attacker could exploit this vulnerability to execute arbitrary code, potentially leading to a takeover of the affected system.

Both vulnerabilities have been rated critical by Microsoft, indicating that they can be easily exploited by attackers and could result in severe consequences for organizations using the affected software. The company has released patches for both flaws, urging customers to apply them as soon as possible to protect their systems from potential attacks.

The Qakbot vulnerability, tracked as CVE-2023-2345, affects the popular enterprise collaboration platform and is caused by a weakness in its authentication mechanism.

Qakbot has released a patch for the vulnerability, and customers are advised to apply it immediately to mitigate potential risks.

Microsoft’s May Patch Tuesday release also includes patches for several other flaws in various products, including Windows, Office, and Dynamics.
