CVE-2024-7875 in TotalAgility
Summary
by MITRE • 12/06/2024
Tungsten Automation (Kofax) TotalAgility in versions all through 7.9.0.25.0.954 is vulnerable to a Reflected XSS attacks through mfpScreenResolutionWidth parameter manipulation in a form sent to an endpoint /TotalAgility/Kofax/BrowserDevice/ScanFront.aspx This allows for injection of a malicious JavaScript code, leading to a possible information leak. Exploitation is possible only while using POST requests and also requires retrieving/generating a proper VIEWSTATE parameter, which limits the risk of a successful attack.

The vulnerability identified as CVE-2024-7875 affects Tungsten Automation Kofax TotalAgility versions up to 7.9.0.25.0.954 and represents a reflected cross-site scripting flaw within the web application's security architecture. This weakness exists in the ScanFront.aspx endpoint which processes browser device information including screen resolution parameters. The vulnerability specifically targets the mfpScreenResolutionWidth parameter that is manipulated through POST requests, creating an attack surface where malicious JavaScript code can be injected into the application's response. The flaw allows attackers to execute arbitrary code within the context of a victim's browser session, potentially leading to unauthorized data access and information disclosure. This type of vulnerability falls under CWE-79 which categorizes improper neutralization of input during web page generation, specifically addressing reflected cross-site scripting conditions where user input is directly included in web responses without proper sanitization or encoding.
The technical implementation of this vulnerability requires specific conditions for successful exploitation, as the attack vector is limited to POST requests rather than GET requests, which provides some inherent protection but does not eliminate the risk entirely. The exploitation process necessitates the retrieval or generation of a valid VIEWSTATE parameter, which serves as an additional security control that significantly reduces the likelihood of successful attacks. The VIEWSTATE parameter acts as a server-side state management mechanism that maintains the state of web forms across postbacks, and its requirement for proper generation creates a barrier that attackers must overcome. This limitation means that casual or automated attacks are less likely to succeed, as they would need to either capture a valid session or reverse-engineer the VIEWSTATE generation algorithm. The vulnerability demonstrates the importance of proper input validation and output encoding in web applications, as the mfpScreenResolutionWidth parameter is not properly sanitized before being reflected back to the user's browser.
The operational impact of CVE-2024-7875 extends beyond simple information leakage to potentially enable more sophisticated attacks within the victim's browser context. When successful, the reflected XSS could allow attackers to access sensitive information, modify user sessions, or redirect users to malicious websites. The attack requires the victim to interact with a specially crafted URL or form submission that includes the malicious JavaScript payload, making it a user-initiated attack vector. This characteristic aligns with the ATT&CK framework's T1566.001 technique for Initial Access through Spearphishing Attachments, where users are tricked into executing malicious code through carefully crafted web interactions. Organizations using affected versions of Kofax TotalAgility face potential risks including unauthorized access to business-critical data, session hijacking, and possible lateral movement within their network infrastructure. The vulnerability impacts the application's integrity and confidentiality, potentially exposing sensitive documents and business processes that the system is designed to protect.
Mitigation strategies for CVE-2024-7875 should prioritize immediate patching of affected systems to address the root cause of the vulnerability. Organizations should implement proper input validation and output encoding mechanisms to prevent malicious JavaScript from being executed within the application context. The implementation of Content Security Policy headers can provide an additional layer of protection by restricting the sources from which scripts can be loaded and executed. Regular security assessments and web application firewalls should be deployed to monitor and block suspicious traffic patterns that may indicate attempted exploitation. Security teams should also implement proper session management controls, including the use of secure and HttpOnly flags for cookies, to prevent session hijacking attacks that could result from successful XSS exploitation. The requirement for VIEWSTATE parameter validation should be reinforced through proper application design principles that ensure all user inputs are properly sanitized before being processed or reflected back to users. Organizations should also consider implementing automated vulnerability scanning tools that can detect similar issues across their web applications and establish security awareness training for users to recognize potential phishing attempts that could leverage this vulnerability.
