Ransomware Intelligence

CISA flags a vulnerability as "used by ransomware" only when a campaign is confirmed. These are flaws extortion groups have already exploited: fixing them first removes the most concrete risk.

CVE-2026-1731 Critical · 9.8 KEV Urgent · 93 Public exploit Ransomware CWE-78 Feb 6, 2026
BeyondTrust Remote Support (RS) and Privileged Remote Access (PRA) OS Command Injection Vulnerability
BeyondTrust Remote Support (RS) and certain older versions of Privileged Remote Access (PRA) contain a critical pre-authentication remote code execution vulnerability. By sending specially crafted requests, an unauthenticated remote attacker may be able to execute operating system commands in the context of the site user.
CVE-2024-51378 Critical · 9.8 KEV Urgent · 93 Public exploit Ransomware CWE-78 Oct 29, 2024
CyberPanel Incorrect Default Permissions Vulnerability
getresetstatus in dns/views.py and ftp/views.py in CyberPanel (aka Cyber Panel) before 1c0c6cb allows remote attackers to bypass authentication and execute arbitrary commands via /dns/getresetstatus or /ftp/getresetstatus by bypassing secMiddleware (which is only for a POST request) and using shell metacharacters in the statusfile property, as exploited in the wild in October 2024 by PSAUX. Versions through 2.3.6 and (unpatched) 2.3.7 are affected.
CVE-2024-9474 High · 7.2 KEV Urgent · 86 Public exploit Ransomware CWE-78 Nov 18, 2024
Palo Alto Networks PAN-OS Management Interface OS Command Injection Vulnerability
A privilege escalation vulnerability in Palo Alto Networks PAN-OS software allows a PAN-OS administrator with access to the management web interface to perform actions on the firewall with root privileges. Cloud NGFW and Prisma Access are not impacted by this vulnerability.
CVE-2024-4577 Critical · 9.8 KEV Urgent · 93 Public exploit Ransomware CWE-78 Jun 9, 2024
PHP-CGI OS Command Injection Vulnerability
In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, when using Apache and PHP-CGI on Windows, if the system is set up to use certain code pages, Windows may use "Best-Fit" behavior to replace characters in command line given to Win32 API functions. PHP CGI module may misinterpret those characters as PHP options, which may allow a malicious user to pass options to PHP binary being run, and thus reveal the source code of scripts, run arbitrary PHP code on the server, etc.
CVE-2023-43208 Critical · 9.8 KEV Urgent · 93 Public exploit Ransomware CWE-78 Oct 26, 2023
NextGen Healthcare Mirth Connect Deserialization of Untrusted Data Vulnerability
NextGen Healthcare Mirth Connect before version 4.4.1 is vulnerable to unauthenticated remote code execution. Note that this vulnerability is caused by the incomplete patch of CVE-2023-37679.
CVE-2017-6884 High · 8.8 KEV Urgent · 74 Public exploit Ransomware CWE-78 Apr 6, 2017
Zyxel EMG2926 Routers Command Injection Vulnerability
A command injection vulnerability was discovered on the Zyxel EMG2926 home router with firmware V1.00(AAQT.4)b8. The vulnerability is located in the diagnostic tools, specifically the nslookup function. A malicious user may exploit numerous vectors to execute arbitrary commands on the router, such as the ping_ip parameter to the expert/maintenance/diagnostic/nslookup URI.
CVE-2018-6530 Critical · 9.8 KEV Urgent · 77 Public exploit Ransomware CWE-78 Mar 6, 2018
D-Link Multiple Routers OS Command Injection Vulnerability
OS command injection vulnerability in soap.cgi (soapcgi_main in cgibin) in D-Link DIR-880L DIR-880L_REVA_FIRMWARE_PATCH_1.08B04 and previous versions, DIR-868L DIR868LA1_FW112b04 and previous versions, DIR-65L DIR-865L_REVA_FIRMWARE_PATCH_1.08.B01 and previous versions, and DIR-860L DIR860LA1_FW110b04 and previous versions allows remote attackers to execute arbitrary OS commands via the service parameter.
CVE-2019-16057 Critical · 9.8 KEV Urgent · 77 Public exploit Ransomware CWE-78 Sep 16, 2019
D-Link DNS-320 Remote Code Execution Vulnerability
The login_mgr.cgi script in D-Link DNS-320 through 2.05.B10 is vulnerable to remote command injection.
CVE-2018-10562 Critical · 9.8 KEV Urgent · 85 Public exploit Ransomware CWE-78 May 4, 2018
Dasan GPON Routers Command Injection Vulnerability
An issue was discovered on Dasan GPON home routers. Command Injection can occur via the dest_host parameter in a diag_action=ping request to a GponForm/diag_Form URI. Because the router saves ping results in /tmp and transmits them to the user when the user revisits /diag.html, it's quite simple to execute commands and retrieve their output.
CVE-2018-11138 Critical · 9.8 KEV Urgent · 93 Public exploit Ransomware CWE-78 May 31, 2018
Quest KACE System Management Appliance Remote Command Execution Vulnerability
The '/common/download_agent_installer.php' script in the Quest KACE System Management Appliance 8.0.318 is accessible by anonymous users and can be abused to execute arbitrary commands on the system.
