Researchers say easy-to-exploit safety bugs in ConnectWise remote-access software program now beneath mass assault – Cyber Tech

Safety researchers say a pair of easy-to-exploit flaws in a well-liked remote-access software utilized by greater than 1,000,000 corporations world wide are actually being mass exploited, with hackers abusing the vulnerabilities to deploy ransomware and steal delicate information.

Cybersecurity big Mandiant stated in a submit on Friday that it has “recognized mass exploitation” of the 2 flaws in ConnectWise ScreenConnect, a well-liked distant entry software that permits IT and technicians to remotely present technical help instantly on buyer programs over the web.

The 2 vulnerabilities comprise CVE-2024-1709, an authentication bypass vulnerability that researchers deemed “embarrassingly simple” for attackers to use, and CVE-2024-1708, a path-traversal vulnerability that permits hackers to remotely plant malicious code, equivalent to malware, on susceptible ConnectWise buyer cases.
