Are you using a Synology router? Then you should definitely update the software, because a new critical vulnerability in Synology routers allows attackers to access and execute DDoS attacks.
New security vulnerability discovered in Synology routers
It was only in June 2022 that Synology closed a critical security hole in its own operating system Synology Router Manager (SRM) via a firmware update, and now the next security hole has already surfaced.
According to the manufacturer, this is a critical vulnerability that allows attackers to exploit multiple vulnerabilities. This allows remote execution of dangerous commands, denial-of-service attacks (DDoS attacks) are also possible, while the vulnerability also allows arbitrary reading of files.
The vendor recommends updating Synology Router Manager (SRM) to the latest version on its own website. For SRM 1.2, upgrading to version 1.2.5-8227-6 closes the gap, while SRM 1.3 requires at least version 1.3.1-9346-3 or later.
