hacker have begun volume tap a third vulnerability pretend Ivanti ’s widely used enterprise VPN appliance , new public data shows .
Last week , Ivanti said it haddiscovered two raw security flaws — tracked as CVE-2024 - 21888 and CVE-2024 - 21893 — pretend Connect Secure , its remote access VPN resolution used by thousands of corp and large constitution worldwide . According to its website , Ivanti has more than 40,000 client , including university , healthcare organization , and banks , whose technology allows their employee to lumber in from outside the office staff .
The disclosure came not long after Ivanti substantiate two earliest bugs in Connect Secure , tracked as CVE-2023 - 46805 and CVE-2024 - 21887 , which security research worker said China - backed hackers had beenexploitingsince December to bankrupt into customer web and steal information .
Now data shows that one of the newly discovered flaws — CVE-2024 - 21893 , a server - side asking forgery flaw — is being mass exploit .
Although Ivanti has since patched the vulnerability , security research worker bear more impact on organizations to come as more hacking radical are work the defect . Steven Adair , founder of cybersecurity company Volexity , a security company that has been tracking victimisation of the Ivanti vulnerabilities , warned that now that substantiation - of - concept exploit code is public , “ any unpatched devices accessible over the cyberspace have in all likelihood been compromised several meter over . ”
Piotr Kijewski , chief executive of Shadowserver Foundation , a non-profit-making establishment that scan and monitors the net for exploitation , told TechCrunch on Thursday that the organisation has observed more than 630 unequalled IPs attempting to exploit the server - side defect , which allows attackers to gain accession to data on vulnerable devices .
That ’s a piercing increase compared to last workweek when Shadowserver saidit had keep 170 unique IPsattempting to exploit the exposure .

Ananalysis of the fresh server - side flawshows the hemipteran can be exploited to bypass Ivanti ’s original mitigation for the initial feat chain of mountains involving the first two vulnerabilities , in effect generate those pre - patch mitigations moot .
Kijewski added that Shadowserver is presently maintain around 20,800 Ivanti Connect Secure twist exposed to the internet , down from 22,500 last week , though he noted that it is n’t known how many of these Ivanti gadget are vulnerable to exploitation .
It ’s not light who is behind the passel victimisation , but security researchers attribute the using of the first two Connect Secure bugs toa China governing – backed hack group likely motivate by espionage .
Ivanti antecedently said it was aware of “ place ” victimization of the server - side bug aimed at a “ limited number of customers . ” Despite repeated requests by TechCrunch this week , Ivanti would not comment on reports that the flaw is undergoing mass exploitation , but it did not dispute Shadowserver ’s findings .
Ivantibegan releasing patchesto customers for all of the vulnerability alongside a 2d set of mitigation earlier this calendar month . However , Ivanti notes in its certificate advisory — last update on February 2 — that it is “ releasing patch for the highest numeral of installs first and then continuing in refuse edict . ”
It ’s not known when Ivanti will make the patch useable to all of its potentially vulnerable customer .
Reports of another Ivanti flaw being mass - work seed day after the U.S. cybersecurity agencyCISA ordered federal agencies to urgently disconnect all Ivanti VPN appliances . The federal agency ’s warning find CISA give bureau just two day to unplug appliances , mention the “ serious threat ” stupefy by the vulnerability under combat-ready attack .
