## The many vulnerabilities Talos discovered in SOHO and industrial wireless routers post-VPNFilter
Since the discovery of the widespread VPNFilter malware in 2018 , Cisco Talos researchers have been researching vulnerabilities in small and home office (SOHO) and industrial routers.
During that research, Talos has worked with vendors to report and mitigate these vulnerabilities, totaling 141 advisories covering 289 CVEs across multiple routers.
Talos is highlighting some of the major issues our researchers discovered over the past several years, including vulnerabilities that an attacker could mostly directly access or those an adversary could chain together to gain elevated access to the devices.
There are several Snort rules that can detect possible exploitation of the vulnerabilitie

[HIGH] Vulnerability Spotlight: Multiple vulnerabilities in Synology SRM (Synology Router Manager)
Cisco Talos recently discovered multiple remote vulnerabilities in software that helps power Synology routers. The bugs exist in Synology Router Manager (SRM) — a Linux-based operating system for Synology routers — and QuickConnect, a feature inside SRM that allows users to remotely connect to their routers. An adversary could use these vulnerabilities to carry out a range of malicious actions, including executing remote code on the device, the exposure of sensitive information regarding the victim’s network and communication with other devices connected to the same network.
In accordance with our coordinated disclosure policy, Cisco Talos worked with Synology to ensure that these issues are resolved and that an update is available for affected customers. One of the vulnerabilities also a
