For organizations that cannot apply the patch immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These systems can detect and block malicious websocket messages, thereby preventing the exploit.<br \/>\nHowever, these are only temporary solutions and cannot substitute for the permanent fix provided by the vendor patch. Therefore, all users should schedule to apply the vendor patch as soon as possible to secure their systems from this <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2024-21591-critical-remote-code-execution-vulnerability-in-juniper-networks-junos-os\/\"  data-wpil-monitor-id=\"29175\">critical vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview CVE-2024-55210 is a critical vulnerability discovered in TOTVS Framework (Linha Protheus) version 12.1.2310.
