CVE-2007-3254 in Xythos
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Xythos Enterprise Document Manager (XEDM) before 5.0.25.8, and 6.x before 6.0.46.1, allow remote authenticated users to inject arbitrary web script or HTML via (1) a saved Workflow name; (2) a Workflow name, related to deletion of a Workflow template; (3) the Content-Type HTTP header; or (4) the name of an uploaded file. NOTE: items 3 and 4 also affect the same version numbers of Xythos Digital Locker (XDL). Some or all vectors might also affect Xythos WebFile Server.

The CVE-2007-3254 vulnerability represents a significant cross-site scripting weakness in Xythos Enterprise Document Manager (XEDM) and related products, specifically impacting versions prior to 5.0.25.8 and 6.x before 6.0.46.1. This vulnerability exposes organizations to remote code execution risks through authenticated user exploitation, where malicious actors can inject arbitrary web scripts or HTML content into the application's interface. The flaw manifests across multiple attack vectors including workflow name handling during save operations, workflow template deletion processes, HTTP header manipulation, and file upload name validation, creating a comprehensive attack surface that could compromise user sessions and potentially lead to full system compromise.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding within the Xythos document management system. When users create or modify workflow names, or when system processes handle file uploads and HTTP headers, the application fails to properly sanitize user-supplied data before rendering it in web responses. This lack of proper sanitization creates XSS opportunities where malicious payloads can be executed in the context of other users' browsers. The vulnerability is particularly concerning because it affects authenticated users, meaning that an attacker must first obtain valid credentials, but once achieved, can leverage these weaknesses to execute persistent attacks against other system users.
The operational impact of CVE-2007-3254 extends beyond simple script injection, as it can enable session hijacking, data exfiltration, and privilege escalation within the document management environment. Attackers can craft malicious workflow names that, when viewed by other authenticated users, execute scripts to steal session cookies, redirect users to phishing sites, or manipulate document access controls. The persistence of these vulnerabilities across multiple product lines including Xythos Digital Locker and potentially WebFile Server indicates a systemic design flaw in the input handling mechanisms of the Xythos suite. This vulnerability directly maps to CWE-79, which specifically addresses Cross-site Scripting flaws in software applications, and aligns with ATT&CK technique T1566 for Phishing and T1071.004 for Application Layer Protocol: DNS, as attackers could use these vulnerabilities to establish persistent access and exfiltrate data through compromised user sessions.
Organizations affected by this vulnerability should immediately implement the vendor-provided patches for XEDM versions 5.0.25.8 and 6.0.46.1, as well as corresponding updates for Xythos Digital Locker and WebFile Server if applicable. Additional mitigations include implementing Content Security Policy headers to prevent unauthorized script execution, conducting comprehensive input validation across all user-supplied data points, and establishing network segmentation to limit the potential impact of successful exploitation. Security monitoring should focus on anomalous workflow creation patterns, unexpected file upload activities, and unusual HTTP header modifications. The vulnerability underscores the critical importance of input sanitization and output encoding in web applications, particularly in enterprise document management systems where user-generated content processing is extensive and sensitive data handling is paramount.
