The flaw, tracked as <a href=\"https:\/\/cybersecuritynews.com\/vmware-tools-and-aria-operations-vulnerabilities\/\" target=\"_blank\" rel=\"noreferrer noopener\">CVE-2025-41244<\/a>, allows an unprivileged local attacker to gain root-level code execution on affected systems.<\/p>\n<p>On September 29, 2025, Broadcom disclosed the vulnerability, which exists within VMware\u2019s guest service discovery features. However, security firm NVISO reported identifying zero-day exploitation of this flaw dating back to mid-October 2024 during incident response engagements.<\/p>\n<p>The vulnerability impacts both VMware Tools and VMware Aria Operations, key components used for managing virtualized environments. Successful exploitation allows a user with low privileges to execute arbitrary code within a privileged context, such as the root user on Linux systems.<\/p>\n<p>The flaw affects two distinct service discovery modes:<\/p>\n<ul class=\"wp-block-list\">\n<li>\n<strong>Credential-less service discovery:<\/strong> In this mode, the vulnerability lies within the VMware Tools component itself, which is widely deployed on guest virtual machines.<\/li>\n<li>\n<strong>Legacy credential-based service discovery:<\/strong> Here, the flaw is located within <a href=\"https:\/\/cybersecuritynews.com\/vmware-aria-operations-vulnerabilities-admin\/\" target=\"_blank\" rel=\"noreferrer noopener\">VMware Aria<\/a> Operations, the management platform for hybrid-cloud workloads.<\/li>\n<\/ul>\n<p>NVISO researchers confirmed the flaw exists in the open-source variant of VMware Tools, <code>open-vm-tools<\/code>, which is distributed with most major Linux distributions.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-0-day-vulnerability-exploitation\"><strong>0-Day Vulnerability Exploitation<\/strong><\/h2>\n<p>The root cause of CVE-2025-41244 is an Untrusted Search Path weakness (CWE-426) in the <code>get-versions.sh<\/code> script, which is responsible for identifying the versions of services running on a virtual machine.<\/p>\n<p>The script uses overly broad regular expressions to locate service binaries. For example, a pattern like <code>\/S+\/httpd<\/code> is designed to find the Apache web server binary, but will also match a file named <code>httpd<\/code> located in a user-writable directory like <code>\/tmp<\/code>.<\/p>\n<p>An attacker can exploit this by placing a malicious executable at a path like <code>\/tmp\/httpd<\/code>. They then run this malicious process and have it open a listening socket. When the VMware service discovery process runs (typically every five minutes), it scans for running services.<\/p>\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEgOH2hQpfWJOxwdQPmhPh3pn7qlbdnJ5s2oAzZBdlO6tt-tiOhttIvGqkYc6N1_TyBgZ5wKPxmvjEQ9-ujtEZNHjQGWWVLGSwV94vdqw1XBmnIIezBFs1XgHMwvYzJ9bXQb0zVQ5owD9UY5wNQLiopQIHhdZVsUPFF9caa0uQ_0wuUpF4GKe1NxCf_2cwPv\/s16000\/5%2520mins.webp?ssl=1\" alt=\"\"><\/figure>\n<p>The flawed script will find and execute the attacker\u2019s malicious binary with the <code>-v<\/code> flag to get its version, but it does so with the elevated privileges of the VMware Tools service. This provides the attacker with a root shell, granting them full control over the system.<\/p>\n<p>NVISO has <a href=\"https:\/\/blog.nviso.eu\/2025\/09\/29\/you-name-it-vmware-elevates-it-cve-2025-41244\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">attributed<\/a> the in-the-wild exploitation to UNC5174, a threat actor believed to be sponsored by the Chinese state. This group has a history of leveraging public exploits for initial access operations.<\/p>\n<p>However, researchers noted that due to the trivial nature of the exploit and the common threat actor practice of naming malware after system binaries (e.g., <code>httpd<\/code>), it is unclear if UNC5174 exploited the flaw intentionally or accidentally. It is possible that other malware has been unintentionally benefiting from this privilege escalation for years.<\/p>\n<p>Organizations can detect exploitation by monitoring for unusual child processes spawned by <code>vmtoolsd<\/code> or the <code>get-versions.sh<\/code> script.
