The vulnerability identified as CVE-2015-7562 represents a critical cross-site scripting flaw affecting TeamPass version 2.1.24 and earlier. This vulnerability resides within the web application's input validation mechanisms, specifically targeting two distinct data entry points that handle user-supplied information. The flaw allows remote attackers to execute malicious scripts within the context of other users' browsers, potentially compromising the entire application ecosystem and user data integrity. This type of vulnerability falls under the category of CWE-79 which specifically addresses Cross-Site Scripting vulnerabilities where untrusted data is improperly incorporated into web pages without proper validation or encoding.
The technical exploitation of this vulnerability occurs through two primary attack vectors that demonstrate the application's insufficient sanitization of user inputs. Attackers can inject malicious scripts through the label value field of an item, which typically serves as a descriptive identifier for stored information within the password management system. Additionally, the vulnerability extends to the name field of roles, which represents another critical data element within the application's access control mechanisms. Both attack vectors exploit the application's failure to properly validate and sanitize user inputs before rendering them in web responses, creating opportunities for persistent or reflected XSS attacks that can be triggered when legitimate users view the compromised data.
The operational impact of this vulnerability extends far beyond simple script execution, as it provides attackers with the capability to hijack user sessions, steal sensitive authentication tokens, and potentially gain unauthorized access to the password management system. In the context of a password manager like TeamPass, this represents a severe risk since the compromised user sessions could provide access to critical credentials and sensitive information stored within the system. The vulnerability also enables attackers to manipulate the application's user interface, potentially redirecting users to malicious websites or displaying fraudulent content that could lead to further exploitation or social engineering attacks. This type of vulnerability aligns with ATT&CK technique T1531 which focuses on credential access through the exploitation of web application vulnerabilities.
Organizations utilizing TeamPass versions prior to the fix should implement immediate mitigations to address this vulnerability. The most effective approach involves implementing comprehensive input validation and output encoding mechanisms that sanitize all user-supplied data before it is processed or rendered within the application. This includes implementing proper HTML entity encoding for all dynamic content and establishing strict input validation rules that reject or sanitize potentially malicious payloads. Additionally, organizations should consider implementing Content Security Policy headers to limit the execution of unauthorized scripts and establish a robust security monitoring system to detect potential exploitation attempts. The vulnerability also highlights the importance of regular security updates and patch management processes, as this issue was resolved in later versions of the TeamPass application through improved input validation mechanisms that align with industry best practices for preventing XSS vulnerabilities.
