Title
GFI HelpDesk < 4.99.9 Stored XSS via editsubject Parameter
Summary
GFI HelpDesk before 4.99.9 contains a stored cross-site scripting vulnerability in the ticket subject field that allows authenticated staff members to inject malicious JavaScript by manipulating the editsubject POST parameter. Attackers can inject XSS payloads through inadequate sanitization in Controller_Ticket.EditSubmit() that bypass the incomplete SanitizeForXSS() method to execute arbitrary JavaScript when other staff members or administrators view the affected ticket.

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.

GFI Archiver MArc.Core Deserialization of Untrusted Data Remote Code Execution Vulnerability
Summary
GFI Archiver MArc.Core 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.Core.Remoting.exe process, which listens on port 8017. 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-27935.

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 HelpDesk < 4.99.10 Stored XSS via Reports Module
Summary
GFI HelpDesk before 4.99.10 contains a stored cross-site scripting vulnerability in the Reports module where the title parameter is passed directly to SWIFT_Report::Create() without HTML sanitization. Attackers can inject arbitrary JavaScript into the report title field when creating or editing a report, and the payload executes when staff members view and click the affected report link in the Manage Reports interface.
Severity
5.4 (Medium)

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.

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 Archiver MArc.Core Deserialization of Untrusted Data Remote Code Execution Vulnerability
Summary
GFI Archiver MArc.Core 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.Core.Remoting.exe process, which listens on port 8017. 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-27935.
