CVE-2014-3878 in IMail
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in the web client interface in Ipswitch IMail Server 12.3 and 12.4, possibly before 12.4.1.15, allow remote attackers to inject arbitrary web script or HTML via (1) the Name field in an add new contact action in the Contacts section or unspecified vectors in (2) an Add Group task in the Contacts section, (3) an add new event action in the Calendar section, or (4) the Task section.

The CVE-2014-3878 vulnerability represents a critical cross-site scripting flaw in Ipswitch IMail Server versions 12.3 and 12.4, with potential impacts extending to earlier versions before 12.4.1.15. This vulnerability resides within the web client interface of the email server software, making it accessible to remote attackers who can exploit it without requiring local system access or authentication. The vulnerability specifically targets four distinct user interaction points within the IMail administrative interface, creating multiple attack vectors that could be leveraged by malicious actors to compromise the system. The flaw allows attackers to inject arbitrary web scripts or HTML code into the server's web interface, potentially enabling them to execute malicious code in the context of other users' browsers.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding within the IMail Server web interface components. When users interact with the Contacts section to add new contacts, the Name field does not properly sanitize user input, allowing attackers to inject malicious scripts that persist in the server's database and execute whenever the contact information is displayed. Similarly, the Add Group functionality in the Contacts section and the add new event actions in the Calendar section, along with tasks in the Task section, all suffer from the same input sanitization deficiencies. These flaws fall under the CWE-79 category of Cross-site Scripting, specifically representing stored XSS vulnerabilities where malicious payloads are stored on the server and executed against unsuspecting users who view the affected content. The vulnerability demonstrates poor security practices in input validation and output encoding, which are fundamental requirements for preventing XSS attacks according to industry security standards.
The operational impact of CVE-2014-3878 extends beyond simple script injection, as it could enable attackers to perform a range of malicious activities through the compromised web interface. An attacker could steal session cookies, allowing them to impersonate legitimate users and gain unauthorized access to administrative functions. The vulnerability could also be exploited to redirect users to malicious websites, harvest sensitive information from authenticated sessions, or execute commands on behalf of the compromised user. Given that IMail Server is commonly used for business email services, successful exploitation could lead to complete compromise of email communications, unauthorized access to sensitive corporate data, and potential lateral movement within network environments. The attack surface is particularly concerning because the web interface is typically accessible to multiple users, including administrators, meaning that a single successful XSS attack could provide attackers with elevated privileges and access to critical system functions.
Mitigation strategies for CVE-2014-3878 should prioritize immediate patching of affected IMail Server versions, with administrators upgrading to version 12.4.1.15 or later where the vulnerability has been addressed. Organizations should implement comprehensive input validation measures across all web application interfaces, ensuring that all user-supplied data is properly sanitized before being stored or displayed. The implementation of Content Security Policy headers can provide additional protection against XSS attacks by restricting the sources from which scripts can be loaded and executed. Network segmentation and access controls should be reinforced to limit exposure of the web interface to only authorized personnel, while regular security audits should verify that input validation mechanisms are properly implemented throughout the application. According to ATT&CK framework, this vulnerability maps to T1059.007 (Command and Scripting Interpreter: JavaScript) and T1566.001 (Phishing: Spearphishing Attachment), as attackers could use the XSS to deliver malicious JavaScript payloads or establish phishing campaigns. Organizations should also consider implementing web application firewalls to detect and block suspicious input patterns, while conducting regular penetration testing to identify similar vulnerabilities in other web applications within their environment.
