CVE-2008-6062 in Dreamweaver
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in ActionScript in arbitrary Shockwave Flash (SWF) files created by Adobe Dreamweaver, when the Insert Flash Video feature is used, allows remote attackers to inject arbitrary web script or HTML via an asfunction: URI in the skinName parameter. NOTE: this may overlap CVE-2007-6242, CVE-2007-6244, or CVE-2007-6637.

This cross-site scripting vulnerability exists within Adobe Dreamweaver's implementation of Shockwave Flash file creation, specifically when utilizing the Insert Flash Video feature. The flaw manifests in how the software processes the skinName parameter within SWF files, creating an attack vector that allows remote adversaries to inject malicious web scripts or HTML content. The vulnerability is particularly concerning because it leverages the asfunction: URI scheme, which is a legitimate mechanism for calling ActionScript functions from external sources, but becomes exploitable when improperly validated.
The technical exploitation occurs through the manipulation of the skinName parameter within Flash video components, where an attacker can inject malicious code that executes in the context of a victim's browser session. This represents a classic XSS vulnerability where untrusted input flows directly into the Flash application's rendering pipeline without proper sanitization or validation. The flaw essentially allows an attacker to bypass normal security boundaries by injecting code that executes within the victim's browser, potentially leading to session hijacking, data theft, or further exploitation of the user's browser environment. The vulnerability is classified under CWE-79 as a failure to sanitize user input, specifically in the context of Flash ActionScript execution.
The operational impact of this vulnerability extends beyond simple script injection, as it enables attackers to create persistent malicious Flash content that can be embedded in websites or delivered through various attack vectors. When victims view web pages containing compromised SWF files, their browsers execute the injected scripts, potentially leading to credential theft, redirection to malicious sites, or exploitation of other browser vulnerabilities. The attack surface is particularly broad given that Dreamweaver is widely used for web development, meaning that vulnerable Flash content could be present on numerous websites, making this a significant concern for web application security.
Mitigation strategies for this vulnerability should focus on input validation and sanitization of parameters within Flash applications, particularly those that handle user-provided data. Organizations should implement proper encoding of user-supplied content before it is processed by Flash components, and consider restricting the use of asfunction: URIs in production environments where possible. The vulnerability overlaps with other reported issues such as CVE-2007-6242, CVE-2007-6244, and CVE-2007-6637, indicating a pattern of Flash-related XSS vulnerabilities that require comprehensive patch management and security testing. Security practitioners should also consider implementing content security policies that restrict the execution of inline scripts and limit the sources from which Flash content can be loaded, aligning with ATT&CK technique T1211 for command and control communications through Flash-based applications.
