CVSS 9.8.
CVE-2024-38094 is a deserialization remote code execution vulnerability in Microsoft SharePoint Server patched in July 2024. Site Owner-authenticated attackers can execute arbitrary code on the SharePoint server. Real-world campaigns chained it with a privilege escalation bug to achieve full domain compromise. CISA added it to the Known Exploited Vulnerabilities catalog in October 2024.
CVE-2024-6387, dubbed regreSSHion by Qualys, is a signal handler race condition in OpenSSH's sshd daemon affecting versions 8.5p1 through 9.7p1 on glibc-based Linux. An unauthenticated attacker can exploit the race condition to achieve remote code execution as root. The vulnerability is a regression of CVE-2006-5051, which was fixed in 2006 and inadvertently reintroduced in OpenSSH 8.5p1 in 2021.
CVE-2024-30078 is a remote code execution vulnerability in the Windows Wi-Fi driver patched in June 2024. An unauthenticated attacker on the same Wi-Fi network, or operating a rogue access point the device connects to, can send a crafted wireless frame to achieve kernel-mode code execution with no user interaction. Every unpatched Wi-Fi-capable Windows device in any shared network environment is in scope.
CVE-2024-4577 is a critical PHP argument injection flaw affecting Windows servers running PHP in CGI mode. A Unicode best-fit character mapping quirk allowed attackers to bypass the CVE-2012-1823 patch and execute arbitrary OS commands without authentication. TellYouThePass ransomware operators weaponized it within hours of the June 2024 PoC release. CVSS 9.8.
CVE-2024-21762 is a CVSS 9.6 out-of-bounds write in Fortinet FortiOS and FortiProxy SSL VPN. An unauthenticated remote attacker sends specially crafted HTTP requests to the SSL VPN web management interface, achieving arbitrary code or command execution. CISA added it to the Known Exploited Vulnerabilities catalog on February 9, 2024, one day after disclosure, confirming active exploitation. Over 150,000 Fortinet devices were estimated to be running vulnerable firmware at time of disclosure.
CVE-2024-23897 is a critical Jenkins CLI vulnerability allowing unauthenticated arbitrary file reads via the args4j argument parser's @ file expansion feature. Disclosed January 2024, the flaw exposed Jenkins controller filesystems including credential stores and cryptographic keys.

CVE-2023-46604 is a CVSS 10.0 deserialization / remote class loading vulnerability in Apache ActiveMQ's OpenWire protocol. An unauthenticated attacker sends a specially crafted ClassInfo message to port 61616, causing the broker to load and execute a Java class from an attacker-controlled HTTP server. Active exploitation by HelloKitty ransomware and Kinsing cryptominer began within days of the advisory. Affects ActiveMQ versions up to 5.15.16, 5.16.7, 5.17.6, and 5.18.3.
CVE-2023-38831 is a code execution vulnerability in WinRAR (< 6.23). An attacker creates a ZIP archive that displays an innocent filename, such as a PDF or image, but actually maps double-click to a hidden script. When the victim double-clicks the apparent document inside WinRAR, a script executes on their system. Exploited by Russian APT28 (Fancy Bear) and North Korean APT40 in targeted spear-phishing campaigns against financial traders and government officials. Affects all WinRAR versions prior to 6.23.
CVE-2023-3519 is a CVSS 9.8 unauthenticated remote code execution vulnerability in Citrix NetScaler ADC and NetScaler Gateway (formerly Citrix ADC / Citrix Gateway). Exploited as a zero-day before any patch was available, it was used to compromise a US critical infrastructure organization. After patches were released, mass exploitation resulted in over 2,000 backdoored appliances within days. Requires the device to be configured as a Gateway or AAA virtual server.
CVE-2023-36884 is a remote code execution vulnerability in Windows Search and Microsoft Office exploited as a zero-day by Russian-nexus group Storm-0978 (RomCom) during the July 2023 NATO summit. Malicious Office documents triggered the flaw without macros or Protected View bypass, targeting NATO member governments. Microsoft disclosed it without a same-day patch, the fix arrived a month later.
CVE-2023-32315 is a critical path traversal vulnerability in the Openfire XMPP messaging server admin console (versions 3.10.0 through 4.7.4), patched in May 2023. An unauthenticated attacker can access the admin console setup wizard by bypassing the authentication filter via a URL path traversal, then upload a malicious Openfire plugin containing arbitrary Java code. Over 3,000 servers were compromised in active exploitation campaigns observed through mid-2023.
CVE-2022-47966 is a CVSS 9.8 unauthenticated RCE vulnerability affecting up to 24 Zoho ManageEngine products. It exploits a vulnerable Apache Santuario (XML Security for Java) component in the SAML SSO implementation, allowing an attacker to execute arbitrary code on any ManageEngine server where SAML-based single sign-on is or was enabled. Exploited by APT41 and other nation-state actors within weeks of the January 2023 disclosure. Affects products widely deployed in enterprise IT management: ServiceDesk Plus, Desktop Central, OpManager, and more.
CVE-2022-41040 and CVE-2022-41082, collectively called ProxyNotShell, are chained vulnerabilities in Microsoft Exchange Server 2013, 2016, and 2019. CVE-2022-41040 is a server-side request forgery flaw that, when chained with CVE-2022-41082, enables an authenticated attacker to achieve remote code execution. Both were exploited in the wild before Microsoft released patches.
CVE-2022-3236 is a critical code injection vulnerability in the User Portal and Webadmin interfaces of Sophos Firewall versions 19.5 MR3 and older. Exploited as a zero-day by a Chinese APT (Storm Cloud / Volt Typhoon cluster), the flaw enabled unauthenticated root-level code execution on internet-facing firewall appliances. Sophos delivered an automatic hotfix but it required manual intervention on restricted networks, leaving many deployments exposed.
CVE-2022-30190 (Follina) is a critical RCE vulnerability in the Microsoft Support Diagnostic Tool (MSDT) triggered via the ms-msdt:// URI scheme from within a malicious Office document. Attackers achieve code execution with no macro prompts, and in some configurations previewing the file in Windows Explorer alone triggers the exploit.
CVE-2022-26134 is a critical OGNL injection vulnerability in Atlassian Confluence Server and Data Center, enabling unauthenticated remote code execution. Disclosed as a zero-day on June 2, 2022 with active exploitation already confirmed, this vulnerability scores 10.0 CVSS. Within hours of technical details becoming public, mass scanning and exploitation began across the internet.
CVE-2022-1388 is a critical authentication bypass vulnerability in the F5 BIG-IP iControl REST management API. Unauthenticated attackers with network access to the management interface can execute arbitrary OS commands as root by manipulating HTTP headers to bypass the API authentication layer. Mass exploitation began within 24 hours of F5's advisory. CISA and FBI issued a joint advisory warning of active exploitation.
CVE-2022-22965 (Spring4Shell) is a critical remote code execution vulnerability in the Spring Framework's data binding component.

CVE-2021-22005 is a critical unauthenticated file upload vulnerability in VMware vCenter Server's CEIP analytics service. Disclosed September 2021, it allowed any attacker with network access to the vCenter HTTPS interface to upload an arbitrary file and achieve remote code execution as the vCenter service account, effectively granting control of every managed virtual machine. Mass exploitation began within 48 hours of disclosure.
CVE-2021-40539 is a critical authentication bypass and remote code execution vulnerability in ManageEngine ADSelfService Plus (versions before build 6114), patched in September 2021. The flaw allowed unauthenticated attackers to access protected REST API endpoints and upload a JSP webshell, achieving code execution on the server. APT41 and at least two other threat actor clusters exploited it against U.S. defense contractors, academic institutions, and critical infrastructure. CVSS 9.8.
CVE-2021-40444 is a remote code execution vulnerability in the MSHTML (Trident) browser engine built into Windows. A malicious Office document embedding a specially crafted ActiveX control causes MSHTML to download and execute a malicious DLL from an attacker-controlled server. No macros are used. No Enable Content prompt appears. The exploit was used in targeted attacks before Microsoft patched it.
