CVE-2014-3774 in TeamPass
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in items.php in TeamPass before 2.1.20 allow remote attackers to inject arbitrary web script or HTML via the group parameter, which is not properly handled in a (1) hid_cat or (2) open_folder form element, or (3) id parameter, which is not properly handled in the open_id form element.

The vulnerability identified as CVE-2014-3774 represents a critical cross-site scripting flaw in TeamPass version 2.1.19 and earlier, a password management application designed for secure password storage and sharing within organizations. This vulnerability resides in the items.php script which handles various user interactions with password items and folder structures. The flaw stems from inadequate input validation and sanitization mechanisms that fail to properly process user-supplied parameters before incorporating them into web responses. The vulnerability specifically affects three distinct parameter handling scenarios within the application's form elements, creating multiple attack vectors for malicious actors to exploit.
The technical implementation of this vulnerability occurs through three primary pathways that all stem from improper parameter handling in the application's user interface components. The first vulnerability manifests when the group parameter is processed within hid_cat form elements, where user input directly influences the generation of dynamic HTML content without adequate sanitization. The second pathway involves the open_folder form element which fails to properly sanitize the group parameter, allowing malicious scripts to be injected into the page context. The third vulnerability occurs in the open_id form element where the id parameter is not properly validated or escaped, creating an additional attack surface for XSS exploitation. These vulnerabilities collectively demonstrate poor input validation practices and inadequate output encoding mechanisms that are fundamental to preventing cross-site scripting attacks.
The operational impact of this vulnerability is substantial as it enables remote attackers to execute arbitrary web scripts or HTML content within the context of authenticated user sessions. This means that an attacker could potentially steal session cookies, modify user interface elements, redirect users to malicious websites, or perform actions on behalf of legitimate users. The vulnerability affects the core functionality of TeamPass by compromising the integrity of user interactions with password items and folder structures, potentially leading to unauthorized access to sensitive password information. Given that TeamPass is designed for enterprise password management, successful exploitation could result in significant data breaches and compromise of organizational security infrastructure. The remote nature of the attack means that no local access or privileged credentials are required to exploit these vulnerabilities, making them particularly dangerous in production environments.
Mitigation strategies for this vulnerability should focus on implementing comprehensive input validation and output encoding mechanisms throughout the application. The primary remediation involves properly sanitizing all user-supplied parameters before incorporating them into dynamic HTML content, specifically addressing the three vulnerable parameter types identified in the exploit. Security measures should include implementing strict input validation rules that reject or escape potentially malicious content, particularly for parameters used in form elements that generate dynamic HTML. Additionally, the application should employ proper output encoding techniques such as HTML entity encoding when displaying user-supplied content in web pages. The recommended solution involves upgrading to TeamPass version 2.1.20 or later, which includes the necessary patches to address these XSS vulnerabilities. Organizations should also implement web application firewalls and content security policies to provide additional defense-in-depth measures. This vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws, and follows attack patterns documented in the MITRE ATT&CK framework under the web application attack category, particularly focusing on credential access and privilege escalation techniques through client-side exploitation.
