CVE-2012-2590 in ESCON SupportPortal
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in ESCON SupportPortal Professional Edition 3.0 allow remote attackers to inject arbitrary web script or HTML via an e-mail message body with (1) a SCRIPT element, (2) a crafted SRC attribute of an IFRAME element, (3) a crafted CONTENT attribute of an HTTP-EQUIV="Set-Cookie" META element, or (4) an innerHTML attribute within an XML document.

The CVE-2012-2590 vulnerability represents a critical cross-site scripting flaw affecting ESCON SupportPortal Professional Edition version 3.0, demonstrating a fundamental failure in input validation and output encoding mechanisms within web applications. This vulnerability exposes the system to remote code execution through malicious script injection, creating a significant attack surface that could be exploited by threat actors to compromise user sessions and access sensitive data. The flaw specifically resides in how the application processes email message bodies, failing to properly sanitize or escape potentially malicious content that users might submit through various HTML elements. The vulnerability's impact extends beyond simple script injection, as it encompasses multiple attack vectors that leverage different HTML attributes and elements, indicating a systemic weakness in the application's security architecture.
The technical exploitation of this vulnerability occurs through four distinct methods that demonstrate the breadth of the attack surface. Attackers can inject malicious scripts using a SCRIPT element directly within email messages, leveraging the browser's execution of embedded javascript code. Additionally, the vulnerability permits exploitation through crafted SRC attributes in IFRAME elements, allowing attackers to load malicious content from external domains and potentially redirect users to phishing sites or execute malicious payloads. The third vector involves manipulating the CONTENT attribute of HTTP-EQUIV="Set-Cookie" META elements, which could enable cookie manipulation attacks and session hijacking. Finally, the innerHTML attribute within XML documents provides another avenue for injection attacks, demonstrating that the vulnerability affects not just traditional HTML parsing but also XML processing within the application. This multi-vector approach aligns with CWE-79, which specifically addresses cross-site scripting vulnerabilities in web applications.
The operational impact of CVE-2012-2590 extends beyond immediate script execution, as successful exploitation could enable attackers to perform session hijacking, steal user credentials, access sensitive support portal data, and potentially escalate privileges within the application. The vulnerability particularly affects organizations using ESCON SupportPortal Professional Edition for customer support management, where users might be tricked into viewing malicious email messages containing the injected scripts. This creates a significant risk for businesses handling confidential customer information, as attackers could potentially access support tickets, user accounts, and sensitive operational data. The vulnerability's persistence in the email message body means that even after initial exploitation, malicious content could continue to affect users who view the compromised messages, creating a prolonged attack window.
Organizations affected by this vulnerability should implement comprehensive input validation and output encoding measures to prevent script injection attacks. The recommended mitigations include implementing strict HTML sanitization filters that remove or escape dangerous elements and attributes, deploying web application firewalls to detect and block malicious payloads, and ensuring proper content security policy headers are implemented to restrict script execution. Security teams should also conduct thorough code reviews to identify similar vulnerabilities in other parts of the application and implement automated security testing during development cycles. The vulnerability's classification under CWE-79 and its alignment with ATT&CK technique T1566.001 for spearphishing with social engineering highlights the importance of user education and awareness programs to prevent users from inadvertently triggering these attacks through malicious email content. Regular security updates and patches should be prioritized, as this vulnerability represents a fundamental flaw in the application's security architecture that requires immediate remediation to prevent exploitation.
