Organizations can find instructions on how to update their PaperCut versions via PaperCut’s vulnerability bulletin.īecause the original submission of these vulnerabilities was done through Trend Micro’s Zero Day Initiative, Trend Micro has also released rules and filters that can help provide protection against the potential exploitation of these vulnerabilities. What can organizations do to prevent and mitigate the risks associated with CVE-2023-27350 and CVE-2023-27351?īoth these vulnerabilities have been fixed in PaperCut MF and NG versions 20.1.7, 21.2.11, and 22.0.9. Considering the previous intrusions that the malicious actors behind LockBit have deployed, we will continue to observe this active threat as it targets more potential victims with possibly even more payloads. LockBit, which is the most prevalent ransomware family according to our Q4 2022 Ransomware Report, continues to dominate as the most active ransomware-as-a-service ( RaaS) provider. Our analysis indicates that the malicious payload enc.exe is the LockBit ransomware (detected by Trend Micro as ), based on the binary found in the user Downloads folder that the malicious actor created. The malicious actors used a temporary hosting site for the malicious payload, one that conveniently deletes all uploaded files after 60 minutes. This PowerShell script downloaded and ran a malicious payload, and used netsh.exe to circumvent the firewall. In this case, the malicious actors chose to run a PowerShell script via the exploited app. Upon the successful exploitation of the vulnerability, pc-app.exe (PaperCut NG/MF) can be used for RCE. Trend Micro Managed XDR observed an instance wherein this vulnerability is believed to have been abused by malicious actors. Based on PaperCut's investigation, the earliest suspicious activity that's possibly related to CVE-2023-27350 dates back to April 14, 2023.
