**Name of the Vulnerable Software and Affected Versions** Microsoft SharePoint Server (affected versions not specified) **Description** The issue is related to insufficient input validation in Microsoft SharePoint Server and SharePoint Enterprise Server. This can be exploited by a remote attacker using specially crafted data to cause a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: Microsoft SharePoint (affected versions not specified) Description: A remote code execution issue exists in Microsoft SharePoint due to the software's failure to properly check the source markup of an application package. This could allow an attacker to run arbitrary code in the context of the SharePoint application pool and the SharePoint server farm account. Exploitation requires a user to upload a specially crafted SharePoint application package to an affected version of SharePoint. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Microsoft SharePoint Server (affected versions not specified) Microsoft SharePoint Foundation (affected versions not specified) Microsoft SharePoint Enterprise Server (affected versions not specified) **Description** The issue is related to insufficient access control in Microsoft SharePoint packages. It allows a remote attacker to elevate their privileges. A remote code execution vulnerability exists when the software fails to check the source markup of an application package, potentially allowing an attacker to run arbitrary code in the context of the SharePoint application pool and the SharePoint server farm account. **Recommendations** For Microsoft SharePoint Server, update to a version that includes the fix for this issue. For Microsoft SharePoint Foundation, update to a version that includes the fix for this issue. For Microsoft SharePoint Enterprise Server, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the application package installation feature until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Microsoft SharePoint Server (affected versions not specified) Microsoft SharePoint Foundation (affected versions not specified) Microsoft SharePoint Enterprise Server (affected versions not specified) **Description** The issue is related to an unlimited file upload vulnerability of a dangerous type. It allows a remote attacker to execute arbitrary code by uploading a specially crafted package. The exploitation requires a user to upload a specially crafted SharePoint application package to an affected version of SharePoint. This could allow an attacker to run arbitrary code in the context of the SharePoint application pool and the SharePoint server farm account. **Recommendations** For Microsoft SharePoint Server, update to a version that includes a fix for this issue. For Microsoft SharePoint Foundation, update to a version that includes a fix for this issue. For Microsoft SharePoint Enterprise Server, update to a version that includes a fix for this issue. As a temporary workaround, consider restricting the upload of application packages to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Microsoft SharePoint Server, SharePoint Foundation, and SharePoint Enterprise Server (affected versions not specified) **Description** The issue is related to a lack of restrictions on file uploads, which can be exploited by a remote attacker to execute arbitrary code by uploading a specially crafted SharePoint application package. This can allow the attacker to run code in the context of the SharePoint application pool and the SharePoint server farm account. The exploitation requires a user to upload a malicious package to an affected version of SharePoint. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Microsoft SharePoint Server (affected versions not specified) **Description** A remote code execution issue exists due to the failure of Microsoft SharePoint Server to properly identify and filter unsafe ASP.Net web controls. This could allow an authenticated attacker to perform actions in the security context of the SharePoint application pool process by using a specially crafted page. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: Microsoft SharePoint Server (affected versions not specified) Description: The issue arises from Microsoft SharePoint Server's failure to properly verify tenant permissions, leading to an elevation of privilege. This could allow an attacker to gain full rights to the affected tenant, enabling them to read unauthorized content, change permissions, and edit or delete content. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
