ShowDoc recently reported "Hackers Revive Five-Year-Old ShowDoc Vulnerability in Global Attacks", a noteworthy cybersecurity incident.
A critical security flaw in ShowDoc, a PHP-based document collaboration tool popular in China, is being actively exploited by threat actors worldwide over five years after a patch was released.
The disruption is felt across the environment, affecting Over 2,000 exposed ShowDoc instances.
In response, and began remediation that includes Apply ShowDoc update to version 3.8.1 or later.
