Title
GFI Archiver MArc.Store Missing Authorization Authentication Bypass Vulnerability
Summary
GFI Archiver MArc.Store Missing Authorization Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of GFI Archiver. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the configuration of the MArc.Store.Remoting.exe process, which listens on port 8018. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM. Was ZDI-CAN-28597.

Title
GFI Archiver MArc.Store Deserialization of Untrusted Data Remote Code Execution Vulnerability
Summary
GFI Archiver MArc.Store Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GFI Archiver. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the configuration of the MArc.Store.Remoting.exe process. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-27936.

Title
GFI MailEssentials AI < 22.4 ListServer.IsPathExist() Absolute Directory Traversal to File Enumeration
Summary
GFI MailEssentials AI versions prior to 22.4 contain an arbitrary directory existence enumeration vulnerability in the ListServer.IsPathExist() web method exposed at /MailEssentials/pages/MailSecurity/ListServer.aspx/IsPathExist. An authenticated user can supply an unrestricted filesystem path via the JSON key \"path\", which is URL-decoded and passed to Directory.Exists(), allowing the attacker to determine whether arbitrary directories exist on the server.

Title
GFI MailEssentials AI < 22.4 ListServer.IsDbExist() Absolute Directory Traversal to File Enumeration
Summary
GFI MailEssentials AI versions prior to 22.4 contain an arbitrary file existence enumeration vulnerability in the ListServer.IsDBExist() web method exposed at /MailEssentials/pages/MailSecurity/ListServer.aspx/IsDBExist. An authenticated user can supply an unrestricted filesystem path via the JSON key \"path\", which is URL-decoded and passed to File.Exists(), allowing the attacker to determine whether arbitrary files exist on the server.
Severity ?
4.3 (Medium)
CWE
- CWE-203 - Observable Discrepancy

Title
GFI Kerio Control Unsigned System Image Upload Root Code Execution
Summary
A remote code execution vulnerability in GFI Kerio Control 9.4.5 allows attackers with administrative access to upload and execute arbitrary code through the firmware upgrade feature. The system upgrade mechanism accepts unsigned .img files, which can be modified to include malicious scripts within the upgrade.sh or disk image components. These modified upgrade images are not validated for authenticity or integrity, and are executed by the system post-upload, enabling root access.
Severity ?
CWE

Title
GFI Kerio Control GFIAgent Missing Authentication on Administrative Interfaces
Summary
A missing authentication vulnerability in the GFIAgent component of GFI Kerio Control 9.4.5 allows unauthenticated remote attackers to perform privileged operations. The GFIAgent service, responsible for integration with GFI AppManager, exposes HTTP services on ports 7995 and 7996 without proper authentication. The /proxy handler on port 7996 allows arbitrary forwarding to administrative endpoints when provided with an Appliance UUID, which itself can be retrieved from port 7995. This results in a complete authentication bypass, permitting access to sensitive administrative APIs.

Title
GFI Kerio Control GFIAgent Authentication Bypass via Proxy Forwarding
Summary
An authentication bypass vulnerability exists in GFI Kerio Control 9.4.5 due to insecure default proxy configuration and weak access control in the GFIAgent service. The non-transparent proxy on TCP port 3128 can be used to forward unauthenticated requests to internal services such as GFIAgent, bypassing firewall restrictions and exposing internal management endpoints. This enables unauthenticated attackers to access the GFIAgent service on ports 7995 and 7996, retrieve the appliance UUID, and issue administrative requests via the proxy. Exploitation results in full administrative access to the Kerio Control appliance.
