CVE-2025-33073 is an elevation of privilege vulnerability affecting the Windows Server Message Block (SMB) client. It stems from improper access control within Windows SMB, potentially allowing an authorized attacker to elevate privileges over a network. To exploit this vulnerability, an attacker could execute a specially crafted script. This script would coerce the victim machine to connect back to the attacker's system using SMB and authenticate, potentially resulting in the attacker gaining SYSTEM privileges.

CVE-2025-33053 is a remote code execution vulnerability affecting the WebDAV client in Microsoft Windows. It stems from insufficient input validation in WebDAV file path handling, allowing an attacker to execute arbitrary code over a network. Successful exploitation requires a user to click on a specially crafted WebDAV URL, potentially leading to unauthorized access to sensitive system resources, compromise of system integrity and confidentiality, or even full control of the affected system. This vulnerability has been actively exploited in the wild.

CVE-2025-49113 is a remote code execution vulnerability affecting Roundcube Webmail versions before 1.5.10 and 1.6.x before 1.6.11. It stems from the insufficient validation of the `_from` parameter in the `program/actions/settings/upload.php` file. This lack of validation allows for PHP Object Deserialization, potentially enabling authenticated users to execute arbitrary code on the Roundcube Webmail server. The vulnerability has been addressed in Roundcube Webmail versions 1.5.10 and 1.6.11.

CVE-2025-32717 is a heap-based buffer overflow vulnerability in Microsoft Office Word. It allows an unauthorized attacker to execute code locally on a vulnerable system. The vulnerability can be exploited through a maliciously crafted RTF file, which could be triggered via the Preview Pane without requiring user interaction. Successful exploitation of this vulnerability could allow an attacker to compromise the system. A security update was released on June 10, 2025, to address this vulnerability in Microsoft 365 Apps.

CVE-2025-43200 is a vulnerability related to how Apple devices process maliciously crafted photos or videos shared via iCloud Link. A logic issue existed that could be exploited through a zero-click attack, meaning it could be triggered without any user interaction. Apple has acknowledged that this vulnerability may have been used in targeted attacks against specific individuals. The vulnerability was addressed with improved checks in iOS 18.3.1, iPadOS 18.3.1, iPadOS 17.7.5, macOS Sequoia 15.3.1, macOS Sonoma 14.7.4, macOS Ventura 13.7.4, watchOS 11.3.1, and visionOS 2.3.1, released on February 10, 2025. Citizen Lab has found forensic evidence that this vulnerability was leveraged to deploy Paragon's Graphite spyware against journalists.

CVE-2025-21420 is an elevation of privilege vulnerability that exists in the Windows Disk Cleanup tool. Successful exploitation could allow an attacker to elevate their privileges to SYSTEM level. As of February 18, 2025, the CVSS v3 score is 7.8, considered High. Microsoft has addressed this vulnerability. It is recommended to apply the necessary security updates to mitigate the risk.

CVE-2024-57727 is a path traversal vulnerability in SimpleHelp remote support software, affecting versions 5.5.7 and older. This flaw allows unauthenticated attackers to download arbitrary files from SimpleHelp servers via specially crafted HTTP requests. The types of files that could be accessed include server configuration files and potentially hashed passwords. This vulnerability, when combined with CVE-2024-57728 and CVE-2024-57726, can lead to full system compromise. Exploitation of this vulnerability chain has been observed in the wild, with threat actors using it to gain initial access to systems. It's recommended to update SimpleHelp to the latest version or uninstall it if no longer needed.

CVE-2025-32711 is a command injection vulnerability affecting Microsoft 365 Copilot. It allows an unauthorized attacker to disclose information over a network. The vulnerability, dubbed "EchoLeak," is a zero-click AI vulnerability, meaning it can be exploited without any user interaction. The attack involves embedding a malicious prompt payload within markdown-formatted content, such as an email. When the AI system's retrieval-augmented generation (RAG) engine parses this content, the payload silently triggers the LLM to extract and return private information from the user's current context. This could potentially expose sensitive data, including chat histories, OneDrive documents, SharePoint content, and Teams conversations. Microsoft has addressed this vulnerability.

CVE-2025-24201 is a zero-day vulnerability found in Apple's WebKit browser engine. This vulnerability allows attackers to bypass the Web Content sandbox using maliciously crafted web content. It affects various Apple devices and operating systems, including iOS, macOS, iPadOS, visionOS, and Safari, as well as Linux and Windows systems where WebKit is utilized. The vulnerability is an out-of-bounds write issue, and Apple has addressed it with improved checks in updates iOS 18.3.2, iPadOS 18.3.2, macOS Sequoia 15.3.2, visionOS 2.3.2, and Safari 18.3.1. This zero-day vulnerability was reportedly exploited in highly sophisticated attacks targeting specific individuals before the release of iOS 17.2, which contained a partial mitigation. While the attacks were not widespread, Apple urges users to install the latest security updates to prevent further exploitation attempts. The vulnerability was discovered by Bill Marczak of The Citizen Lab at the University of Toronto. It affects a wide range of Apple devices, including iPhone XS and later, several iPad models, Macs running macOS Sequoia, and Apple Vision Pro.

CVE-2025-37899 is a use-after-free vulnerability found in the ksmbd component of the Linux kernel, which is an in-kernel server implementing the SMB3 protocol for file sharing over networks. Specifically, the vulnerability exists in the session logoff handler. The vulnerability occurs because the `sess->user` object can be freed by one thread processing a logoff command while another thread, handling a new connection's session setup request, might still be accessing the same `sess->user` object. This concurrent access can lead to memory corruption and potentially allow attackers to execute arbitrary code with kernel privileges.
