CVE-2005-3128 Scanner

SquirrelMail Address Add is a plugin used with the SquirrelMail email client to enhance email address management features. It is commonly employed by organizations using SquirrelMail for improved email management. This plugin serves to facilitate the storage and retrieval of email contacts. Typically, organizations that have integrated the SquirrelMail platform within their email systems utilize Address Add for increased usability and functionality. The software is crucial for users aiming to streamline address management tasks within their webmail context. Overall, it enhances SquirrelMail's utility, making email management more efficient and user-friendly.

The Cross-Site Scripting (XSS) vulnerability detected in the SquirrelMail Address Add plugin arises from inadequate input sanitization. Such vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users. In this specific case, it enables the execution of arbitrary scripts in the browser context under specific circumstances. The attacker can leverage this to steal cookie-based credentials and potentially spoof otherwise restricted actions. These kinds of vulnerabilities are critical in undermining user security as they turn users into attack vectors against systems.

From a technical perspective, the vulnerability exists because the application improperly sanitizes user-supplied input on a specific endpoint: the "add.php" script of the Address Add plugin. Attackers can craft a request that injects script code via the "first" parameter, which, when executed, results in a XSS condition. The exploit involves code injection that precisely fits into a typical browser event context to set off the script execution. The detection involves checking the server response for the presence of this unsanitized script as both a body word and within HTML headers camouflaged. Proper exploitation leads to script execution, particularly using alert boxes to confirm execution.

Potential impacts of exploiting this vulnerability include credential theft and session hijacking. When users' cookies are captured, it could allow attackers to impersonate them within the application context. This form of attack could also facilitate phishing campaigns by making the compromise look legitimate and originating inside the trusted environment. Additionally, active exploitation could create opportunities to gather sensitive information accessible within subsequent authenticated sessions otherwise protected under normal circumstances. Ultimately, XSS can serve concurrent attacks to extend a penetration and propagation attack strategy across network frameworks or further into web applications linked together.
