The latest Patch Tuesday update has highlighted a growing number of critical vulnerabilities that have emerged recently. In this article, we will delve into the details of these vulnerabilities and their implications for cybersecurity. We will explore the command injection vulnerability in Windows PowerShell (CVE-2025-54100) as well as the similar vulnerability in GitHub Copilot for JetBrains (CVE-2025-64671). Furthermore, we will examine the impact of IDEsaster, a set of security vulnerabilities collectively named by security researcher Ari Marzouk. The article will conclude with an overview of the comprehensive patch released by Microsoft for 56 security flaws in various Windows products and its implications for cybersecurity.
CVE-2025-54100: Command injection vulnerability in Windows PowerShell, allowing arbitrary code execution.CVE-2025-64671: Command injection vulnerability in GitHub Copilot for JetBrains, also allowing arbitrary code execution.Multiple software vendors have released security patches to address various vulnerabilities.Microsoft has issued a comprehensive patch for 56 security flaws, with CVE-2025-62221 being the most severe (CVSS score: 7.8).CVE-2025-62221 allows an authorized attacker to elevate privileges locally and obtain SYSTEM permissions.
CVE-2025-54100, a command injection vulnerability in Windows PowerShell, was recently disclosed by Action1's Alex Vovk. According to Vovk, this flaw allows an unauthenticated attacker to execute arbitrary code locally in the security context of a user who runs a crafted PowerShell command, such as Invoke-WebRequest.
The CVE-2025-54100 vulnerability is particularly concerning because it can be combined with common attack patterns to lead to code execution and implant deployment. An attacker could use social engineering tactics to persuade a user or admin to run a PowerShell snippet using Invoke-WebRequest, allowing a remote server to return crafted content that triggers the parsing flaw and results in code execution.
In addition to CVE-2025-54100, GitHub Copilot for JetBrains has also been identified as vulnerable to command injection (CVE-2025-64671). This vulnerability allows an unauthorized attacker to execute code locally. According to Kev Breen, senior director of cyber threat research at Immersive, the threat posed by this vulnerability is significant because it can be used in conjunction with other attack patterns.
The CVE-2025-64671 vulnerability was recently disclosed as part of a broader set of security vulnerabilities collectively known as IDEsaster. According to Ari Marzouk, a security researcher who discovered and reported the flaw, these vulnerabilities arise from adding agentic capabilities to integrated development environments (IDEs), which exposes new security risks in the process.
The IDEsaster vulnerability combines prompt injections against artificial intelligence (AI) agents embedded into IDEs with the base IDE layer. This combination results in information disclosure or command execution attacks. As Marzouk noted, this type of attack is not novel and utilizes an "old" attack chain involving a vulnerable tool that allows for bypassing user-configured allow lists.
In addition to CVE-2025-54100 and CVE-2025-64671, numerous other vulnerabilities have been identified in various software products. For example, Adobe, Amazon Web Services, AMD, Arm, ASUS, Atlassian, Bosch, Broadcom (including VMware), Canon, Cisco, Citrix, CODESYS, Dell, Devolutions, Drupal, F5, Fortinet, Fortra, GitLab, Google Android and Pixel, Google Chrome, Google Cloud, Google Pixel Watch, Hitachi Energy, HP, HP Enterprise (including Aruba Networking and Juniper Networks), IBM, Imagination Technologies, Intel, Ivanti, Lenovo, Linux distributions AlmaLinux, Alpine Linux, Amazon Linux, Arch Linux, Debian, Gentoo, Oracle Linux, Mageia, Red Hat, Rocky Linux, SUSE, and Ubuntu, MediaTek, Mitsubishi Electric, MongoDB, Moxa, Mozilla Firefox and Firefox ESR, NVIDIA, OPPO, Progress Software, Qualcomm, React, Rockwell Automation, Samsung, SAP, Schneider Electric, Siemens, SolarWinds, Splunk, Synology, TP-Link, WatchGuard, and Zyxel have all issued security patches.
Furthermore, Microsoft has released a comprehensive patch for 56 security flaws in various Windows products. The most severe of these vulnerabilities is CVE-2025-62221 (CVSS score: 7.8), which is classified as an active exploit vulnerability that can allow an authorized attacker to elevate privileges locally and obtain SYSTEM permissions.
According to Adam Barnett, lead software engineer at Rapid7, the Cloud Files minifilter driver is used by OneDrive, Google Drive, iCloud, and others, but it would still be present on a system even if none of those apps were installed. The vulnerability can be exploited using an attacker's ability to gain access to a susceptible system through other means, such as phishing or remote code execution.
The successful exploitation of CVE-2025-62221 requires an attacker to obtain low-privileged access and then chain it with the vulnerability to seize control of the host. Armed with this access, the attacker can deploy kernel components or abuse signed drivers to evade defenses and maintain persistence.
In total, Microsoft has addressed a total of 1,275 CVEs in 2025, according to data compiled by Fortra. This represents the second consecutive year that Windows has patched over 1,000 CVEs. It is also the third time that Patch Tuesday has been used to address a large number of vulnerabilities.
In related news, Tenable's Satnam Narang noted that 2025 marks the second consecutive year in which Patch Tuesday has been used to address a large number of vulnerabilities. The update includes a total of 17 shortcomings in the Chromium-based Edge browser since the release of the November 2025 Patch Tuesday update.
Furthermore, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added CVE-2025-62221 to the Known Exploited Vulnerabilities (KEV) catalog, mandating Federal Civilian Executive Branch (FCEB) agencies to apply the patch by December 30, 2025.
Summary:
The latest Patch Tuesday update includes a comprehensive set of security patches for various Windows products. Among these, CVE-2025-54100 and CVE-2025-64671 represent significant command injection vulnerabilities in Windows PowerShell and GitHub Copilot for JetBrains, respectively. Additionally, numerous other software vendors have released security patches to address a range of vulnerabilities. Microsoft has also issued a comprehensive patch for 56 security flaws in various products, with the most severe vulnerability being CVE-2025-62221. The successful exploitation of this vulnerability can allow an authorized attacker to elevate privileges locally and obtain SYSTEM permissions.
