CVE-2024-21887

Tenable Blog · May 27, 2026

Tenable Research has developed a graph-based model linking 600+ threat groups to real-world customer exposures. It reveals which vulnerabilities sit at the intersection of severity, active exploitation, and organizational risk.Key takeawaysThe "patch everything" strategy is dead: Vulnerability prioritization based on exploitation risk offers a path forward. A directed graph model linking 600+ threat actors to vulnerabilities in 7,800 customer environments reveals that 68% of organizations carry at least one CVE previously exploited by a named adversary, and 321 tracked threat groups can reach at least one customer environment through an active vulnerability. Prevalence of "Elite Arsenal" CVEs requires immediate attention: The 242 "Elite Arsenal" CVEs — those meeting all three criteria of critical VPR (≥ 9), CISA KEV listing, and documented threat group exploitation — are nearly universally present across the studied customer base, with 241 of 242 actively detected. More than half are five or more years old, and 78% of the persistently exploited core are simultaneously weaponized by nation-state APTs, commodity malware operators, and ransomware gangs. Non-CVE exposures are universally dangerous: Non-CVE exposures, including misconfigurations, weak credentials, and end-of-life software, are present in virtually 100% of studied organizations, with 60% carrying at least one that maps to a tracked threat actor's preferred techniques. Preliminary modeling suggests these exposures may confer more breach risk than CVE-linked findings, yet no industry-standard scoring infrastructure exists to prioritize them.While the first two posts in this blog series documented the accelerating vulnerability flood and the widening remediation gap, today we answer the outstanding question: Where do these forces actually collide inside customer environments? Using a directed graph model that maps more than 600 tracked threat groups to vulnerabilities observed across 7,800 organizations,...

Written by: Casey Charrier, James Sadowski, Clement Lecigne, Vlad Stolyarov Executive Summary Google Threat Intelligence Group (GTIG) tracked 75 zero-day vulnerabilities exploited in the wild in 2024, a decrease from the number we identified in 2023 (98 vulnerabilities), but still an increase from 2022 (63 vulnerabilities). We divided the reviewed vulnerabilities into two main categories: end-user platforms and products (e.g., mobile devices, operating systems, and browsers) and enterprise-focused technologies, such as security software and appliances.  Vendors continue to drive improvements that make some zero-day exploitation harder, demonstrated by both dwindling numbers across multiple categories and reduced observed attacks against previously popular targets. At the same time, commercial surveillance vendors (CSVs) appear to be increasing their operational security practices, potentially leading to decreased attribution and detection. We see zero-day exploitation targeting a greater number and wider variety of enterprise-specific technologies, although these technologies still remain a smaller proportion of overall exploitation when compared to end-user technologies. While the historic focus on the exploitation of popular end-user technologies and their users continues, the shift toward increased targeting of enterprise-focused products will require a wider and more diverse set of vendors to increase proactive security measures in order to reduce future zero-day exploitation attempts. For a deeper look at the trends discussed in this report, along with recommendations for defenders, register for our upcoming zero-day webinar. Scope  This report describes what Google Threat Intelligence Group (GTIG) knows about zero-day exploitation in 2024. We discuss how targeted vendors and exploited products drive trends that reflect threat actor goals and shifting exploitation approaches, and then closely examine several examples of zero-day exploitation from 2024 that…
