CVE-2026-22676 (GCVE-0-2026-22676)
Vulnerability from cvelistv5 – Published: 2026-04-15 20:45 – Updated: 2026-04-16 12:05

Title
Barracuda RMM < 2025.2.2 Privilege Escalation via Insecure Directory Permissions
Summary
Barracuda RMM versions prior to 2025.2.2 contain a privilege escalation vulnerability that allows local attackers to gain SYSTEM-level privileges by exploiting overly permissive filesystem ACLs on the C:\Windows\Automation directory. Attackers can modify existing automation content or place attacker-controlled files in this directory, which are then executed under the NT AUTHORITY\SYSTEM account during routine automation cycles, typically succeeding within the next execution cycle.

Title
Barracuda RMM < 2025.1.1 Service Center Absolute Path Traversal RCE
Summary
Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, does not verify the URL defined in an attacker-controlled WSDL that is later loaded by the application. This can lead to arbitrary file write and remote code execution via webshell upload.

CVE-2010-20109 (GCVE-0-2010-20109)

Title
Barracuda Spam & Virus Firewall "locale" Path Traversal
Summary
Barracuda products, confirmed in Spam & Virus Firewall, SSL VPN, and Web Application Firewall versions prior to October 2010, contain a path traversal vulnerability in the view_help.cgi endpoint. The locale parameter fails to properly sanitize user input, allowing attackers to inject traversal sequences and null-byte terminators to access arbitrary files on the underlying system. By exploiting this flaw, unauthenticated remote attackers can retrieve sensitive configuration files such as /mail/snapshot/config.snapshot, potentially exposing credentials, internal settings, and other critical data.
