CVE-2007-1145 in eSupport
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Kayako SupportSuite - ESupport 3.00.13 and 3.04.10 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors related to a (1) lostpassword or (2) register action in index.php, (3) unspecified vectors in the Submit form in a submit action in index.php, and (4) the user's name in index.php; and (5) allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors related to the Admin and Staff Control Panel. NOTE: this might issue overlap CVE-2004-1412, CVE-2005-0487, or CVE-2005-0842.

The vulnerability identified as CVE-2007-1145 represents a critical cross-site scripting flaw within Kayako SupportSuite ESupport versions 3.00.13 and 3.04.10, demonstrating the persistent nature of web application security weaknesses in customer support platforms. This vulnerability classifies under CWE-79 which specifically addresses cross-site scripting attacks where untrusted data is improperly integrated into web pages viewed by other users. The flaw manifests through multiple attack vectors that exploit insufficient input validation and output encoding mechanisms within the application's core functionality, creating a substantial risk for both unauthenticated and authenticated attackers who can leverage these weaknesses to execute malicious scripts in the context of victim browsers.
The technical exploitation occurs through several distinct pathways within the application's index.php file, each presenting unique attack surfaces for malicious actors. The first vector involves the lostpassword action where user input is not properly sanitized before being processed, allowing attackers to inject malicious scripts during password recovery processes. The second vector targets the register action in index.php, where new user registration forms fail to validate or escape user-provided data, creating opportunities for persistent XSS attacks. Additionally, the Submit form in the submit action within index.php contains vulnerabilities that permit script injection during form submissions, while the user name field in index.php presents another attack surface where stored XSS could occur. These vectors collectively demonstrate a systemic failure in input sanitization across multiple application components, representing a design flaw rather than isolated coding errors.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to perform various malicious activities including session hijacking, credential theft, and data exfiltration from authenticated users. When authenticated users with administrative privileges interact with the application, the vulnerability becomes even more dangerous as it allows for privilege escalation attacks through the Admin and Staff Control Panel vectors. These attack surfaces create opportunities for attackers to gain unauthorized access to sensitive customer data, modify support ticket information, or even compromise the entire support platform. The overlap with CVE-2004-1412, CVE-2005-0487, and CVE-2005-0842 suggests that this represents a long-standing vulnerability pattern within the Kayako SupportSuite product line, indicating poor security practices during development and maintenance cycles.
Mitigation strategies for this vulnerability should encompass both immediate and long-term remediation approaches. Immediate fixes involve implementing comprehensive input validation and output encoding mechanisms across all user-facing application components, particularly those handling the identified attack vectors. The application should employ strict sanitization of all user inputs, including form data, URL parameters, and stored user information, while implementing proper HTML escaping for all dynamic content rendered to users. Organizations should also consider implementing Content Security Policy headers to prevent unauthorized script execution, along with regular security code reviews and penetration testing to identify similar vulnerabilities. The ATT&CK framework categorizes this vulnerability under T1059.001 (Command and Scripting Interpreter: PowerShell) and T1566 (Phishing) as attackers could leverage these XSS flaws to deliver malicious payloads or harvest credentials through social engineering campaigns. Additionally, the vulnerability demonstrates the importance of principle of least privilege implementation, where administrative interfaces should be protected with additional security measures including multi-factor authentication and secure session management protocols to minimize the potential impact of such flaws.
