The vulnerability identified as CVE-2002-1805 represents a classic cross-site scripting flaw within the DaCode 1.2.0 web application framework. This security weakness specifically manifests when the application fails to properly sanitize user input containing javascript code within image tags, creating an avenue for malicious actors to execute unauthorized scripts in the context of other users' browsers. The vulnerability falls under the broader category of CWE-79 Improper Neutralization of Input During Web Page Generation, which is a fundamental web application security concern that has persisted across decades of software development.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious image tag containing javascript code that gets processed and rendered by the vulnerable application. When other users browse pages containing this malicious content, their browsers execute the embedded javascript code, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The attack vector specifically targets the IMG tag element, which is commonly used in web pages and often bypasses basic input validation mechanisms that might otherwise detect malicious payloads in other HTML elements.
This vulnerability presents significant operational impact for organizations using DaCode 1.2.0, as it enables attackers to compromise user sessions and potentially gain unauthorized access to sensitive information. The remote nature of the attack means that malicious actors can exploit this weakness without requiring physical access to the target system or network. From an attacker's perspective, this vulnerability aligns with ATT&CK technique T1059.007 Command and Scripting Interpreter: JavaScript, as it leverages javascript execution capabilities to manipulate web page behavior and user interactions. The vulnerability essentially transforms legitimate web application functionality into a weapon for executing malicious code against unsuspecting users.
Mitigation strategies for CVE-2002-1805 require immediate implementation of proper input sanitization and output encoding mechanisms within the DaCode framework. Organizations should implement comprehensive HTML escaping for all user-supplied content, particularly when processing image tags and other HTML elements that may contain dynamic content. The fix should involve validating and sanitizing all input data to remove or encode potentially dangerous characters and script tags before rendering them in web pages. Additionally, implementing a content security policy that restricts script execution from untrusted sources can provide additional protection against exploitation attempts. Security patches or updates to the DaCode application should be prioritized, as this vulnerability represents a critical security risk that can be exploited without user interaction and can cause widespread damage to affected systems and user data integrity.
