A hacker has posted a checklist of one-line exploits to steal VPN credentials from nearly 50,000 Fortinet VPN gadgets.
Current on the checklist of weak targets are domains belonging to excessive avenue banks and authorities organizations from world wide.
Researchers discover hundreds of targets
The vulnerability being referred to right here is CVE-2018-13379, a path traversal flaw impacting numerous unpatched Fortinet FortiOS SSL VPN gadgets.
By exploiting this vulnerability, unauthenticated distant attackers can entry system recordsdata by way of specifically crafted HTTP requests.
The exploit posted by the hacker lets attackers entry the sslvpn_websession recordsdata from Fortinet VPNs to steal login credentials. These stolen credentials might then be used to compromise a network and deploy ransomware.
Though the 2018 bug was publicly disclosed over a year ago, researchers have noticed round 50,000 targets that may nonetheless be focused by attackers.
This week, risk intelligence analyst Bank_Security discovered a hacker discussion board thread the place a risk actor shared a big 49,577 machine checklist of such exploitable targets
After analyzing the checklist, it was discovered that the weak targets included authorities domains from world wide, and people belonging to well-known banks and finance corporations.
