Advanced persistent threat (APT) actors have been exploiting recently disclosed vulnerabilities affecting enterprise VPN products from Fortinet, Palo Alto Networks and Pulse Secure, the UK’s National Cyber Security Centre (NCSC) warns.
The NCSC, which is part of the UK’s GCHQ intelligence agency, issued an alert this week to warn organizations that they may be targeted if they use the affected products.
“This activity is ongoing, targeting both UK and international organisations. Affected sectors include government, military, academic, business and healthcare,” the NCSC said.
According to the organization, APTs have been targeting several vulnerabilities, including CVE-2019-11510 and CVE-2019-11539, which affect Pulse Secure products, CVE-2018-13379,
CVE-2018-13382 and CVE-2018-13383, which affect Fortinet products, and CVE-2019-1579, which impacts Palo Alto Networks products.
These and other vulnerabilities in Pulse Secure, Fortinet and Palo Alto Networks VPNs were disclosed this summer by Orange Tsai and Meh Chang of the research team at security consulting firm DEVCORE. Shortly after their disclosure, which included technical details, several proof-of-concept (PoC) exploits were made public.
The flaws can be exploited remotely to infiltrate corporate networks, eavesdrop on communications, and steal potentially sensitive information, the researchers warned.
A few weeks after disclosure, the first attack attempts targeting Fortinet and Pulse Secure systems were spotted.
Analysts from Microsoft’s Threat Intelligence Center revealed in early September that a threat group tracked by the company as MANGANESE had been using the vulnerabilities in its attacks since mid-July, ..
