Customers of Cleo-managed file switch software program are being urged to make sure that their cases will not be uncovered to the web following reviews of mass exploitation of a vulnerability affecting totally patched programs.
Cybersecurity firm Huntress stated it found proof of menace actors exploiting the difficulty en masse on December 3, 2024. The vulnerability, which impacts Cleo’s LexiCom, VLTransfer, and Concord software program, issues a case of unauthenticated distant code execution.
The safety gap is tracked as CVE-2024-50623, with Cleo noting that the flaw is the results of an unrestricted file add that might pave the best way for the execution of arbitrary code.
The Illinois-based firm, which has over 4,200 prospects internationally, has since issued one other advisory (CVE pending), warning of a separate “unauthenticated malicious hosts vulnerability that could lead to remote code execution.”
The event comes after Huntress stated the patches launched for CVE-2024-50623 don’t utterly mitigate the underlying software program flaw. The problem impacts the beneath merchandise and is predicted to be patched later this week –
- Cleo Concord (as much as model 5.8.0.23)
- Cleo VLTrader (as much as model 5.8.0.23)
- Cleo LexiCom (as much as model 5.8.0.23)
Within the assaults detected by the cybersecurity firm, the vulnerability has been discovered to be exploited to drop a number of information, together with an XML file that is configured to run an embedded PowerShell command that is liable for retrieving a next-stage Java Archive (JAR) file from a distant server.
Particularly, the intrusions leverage the actual fact information positioned within the “autorun” sub-directory inside the set up folder and are instantly learn, interpreted, and evaluated by the prone software program.
As many as no less than 10 companies have had their Cleo servers compromised, with a spike in exploitation noticed on December 8, 2024, at round 7 a.m. UTC. Proof gathered thus far pins the earliest date of exploration to December 3, 2024.
Sufferer organizations span shopper product firms, logistics and transport organizations, and meals suppliers. Customers are suggested to make sure that their software program is up-to-date to make sure that they’re protected towards the menace.
Ransomware teams like Cl0p (aka Lace Tempest) have beforehand set their sights on numerous managed file switch instruments previously, and it seems to be like the newest assault exercise is not any totally different.
In response to safety researcher Kevin Beaumont (aka GossiTheDog), “Termite ransomware group operators (and maybe other groups) have a zero-day exploit for Cleo LexiCom, VLTransfer, and Harmony.”
Cybersecurity firm Rapid7 stated it additionally has confirmed profitable exploitation of the Cleo challenge towards buyer environments. It is value noting that Termite has claimed duty for the latest cyber assault on provide chain agency Blue Yonder.
Broadcom’s Symantec Risk Hunter Staff advised The Hacker Information that “Termite appears to be using a modified version of Babuk ransomware, which, when executed on a machine, encrypts targeted files and adds a .termite extension.”
“Since we saw that Blue Yonder had an instance of Cleo’s software open to the internet via Shodan, and Termite has claimed Blue Yonder amongst its victims, which was also confirmed by their listing and open directory of files, I’d say that Gossi is correct in his statement,” Jamie Levy, Huntress’ Director of Adversary Techniques, advised the publication.
“For what it’s worth, there have been some rumblings that Termite might be the new Cl0p, there is some data that seems to support this as Cl0p’s activities have waned while Termite’s activities have increased. They are also operating in some similar fashions. We’re not really in the attribution game, but it wouldn’t be surprising at all if we are seeing a shift in these ransomware gangs at the moment.”
