The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to time-based SQL Injection via the 'order' parameter in all versions up to, and including, 4.2.6.9.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Falang multilanguage for WordPress plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions in all versions up to, and including, 1.3.52. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update and delete translations and expose the administrator email address.

The Lightbox & Modal Popup WordPress Plugin – FooBox plugin for WordPress is vulnerable to DOM-based Stored Cross-Site Scripting via HTML data attributes in all versions up to, and including, 2.7.28 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Search & Filter Pro WordPress plugin before 2.5.18 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

The Fuse Social Floating Sidebar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the file upload functionality in all versions up to, and including, 5.4.10 due to insufficient validation of SVG files. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Summary:
Microsoft was notified that an elevation of privilege vulnerability exists in Windows based systems supporting Virtualization Based Security (VBS) including a subset of Azure Virtual Machine SKUS; enabling an attacker with administrator privileges to replace current versions of Windows system files with outdated versions. By exploiting this vulnerability, an attacker could reintroduce previously mitigated vulnerabilities, circumvent some features of VBS, and exfiltrate data protected by VBS.
Microsoft is developing a security update to mitigate this threat, but it is not yet available. Guidance to help customers reduce the risks associated with this vulnerability and to protect their systems until the mitigation is available in a Windows security update is provided in the Recommended Actions section of this CVE.
This CVE will be updated when the mitigation is available in a Windows security update. We highly encourage customers to subscribe to Security Update Guide notifications to receive an alert when this update occurs.

The News Flash theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.1.0 via deserialization of untrusted input from the newsflash_post_meta meta value. This makes it possible for authenticated attackers, with Editor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

The MultiPurpose theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.2.0 via deserialization of untrusted input through the 'wpeden_post_meta' post meta. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Summary
Microsoft was notified that an elevation of privilege vulnerability exists in Windows Backup, potentially enabling an attacker with basic user privileges to reintroduce previously mitigated vulnerabilities or circumvent some features of Virtualization Based Security (VBS). However, an attacker attempting to exploit this vulnerability requires additional interaction by a privileged user to be successful.
Microsoft is developing a security update to mitigate this threat, but it is not yet available. Guidance to help customers reduce the risks associated with this vulnerability and to protect their systems until the mitigation is available in a Windows security update is provided in the Recommended Actions section of this CVE.
This CVE will be updated, and customers will be notified when the official mitigation is available in a Windows security update. We highly encourage customers to subscribe to Security Update Guide notifications to receive an alert when this update occurs.
Details
A security researcher informed Microsoft of an elevation of privilege vulnerability in Windows Backup potentially enabling an attacker with basic user privileges to reintroduce previously mitigated vulnerabilities or circumvent some features of VBS. For exploitation to succeed, an attacker must trick or convince an Administrator or a user with delegated permissions into performing a system restore which inadvertently triggers the vulnerability.
Microsoft is developing a security update that will mitigate this vulnerability, but it is not yet available. This CVE will be updated with new information and links to the security updates once available. We highly encourage customers subscribe to Security Update Guide notifications to be alerted of updates. See Microsoft Technical Security Notifications and Security Update Guide Notification System News: Create your profile now – Microsoft Security Response Center.
Microsoft is not aware of any attempts to exploit this vulnerability. However, a public presentation regarding this vulnerability was hosted at BlackHat on August 7, 2024. The presentation was appropriately coordinated with Microsoft but may change the threat landscape. Customers concerned with these risks should reference the guidance provided in the Recommended Actions section to protect their systems.
Recommended Actions
The following recommendations do not mitigate the vulnerability but can be used to reduce the risk of exploitation until the security update is available.

Audit users with permission to perform Backup and Restore operations to ensure only the appropriate users can perform these operations.

Audit: Audit the use of Backup and Restore privilege (Windows 10) – Windows 10 | Microsoft Learn

Implement an Access Control List or Discretionary Access Control Lists to restrict the access or modification of Backup files and perform Restore operations to appropriate users, for example administrators only.

Discretionary Access Control Lists (DACL)

Auditing sensitive privileges used to identify access, modification, or replacement of Backup related files could help indicate attempts to exploit this vulnerability.

The The Next theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.1.0 via deserialization of untrusted input from the wpeden_post_meta post meta value. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
