TeamPass version 2.1.27.4 and earlier contains a critical sql injection vulnerability in the users.queries.php file that allows remote attackers to execute arbitrary sql commands against the underlying database. This vulnerability arises from insufficient input validation and improper parameter handling when processing user-supplied data within sql query construction. The flaw exists in the application's authentication and user management modules where user input is directly concatenated into sql statements without proper sanitization or prepared statement usage. Attackers can exploit this weakness by crafting malicious input parameters that manipulate the sql query structure, potentially leading to unauthorized database access, data exfiltration, or complete system compromise.
The technical implementation of this vulnerability stems from the application's failure to employ proper input validation mechanisms and parameterized queries. When user credentials or identification data are processed through the users.queries.php endpoint, the application does not adequately sanitize or escape input values before incorporating them into sql commands. This represents a classic sql injection vulnerability classified under cwe-89, which specifically addresses improper neutralization of special elements used in sql commands. The vulnerability is particularly dangerous because it affects core user management functionality, potentially allowing attackers to bypass authentication mechanisms and gain elevated privileges within the system.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to manipulate user accounts, access sensitive information, and potentially escalate privileges within the TeamPass environment. Successful exploitation could result in unauthorized access to password databases, user account compromise, and potential lateral movement within networks where TeamPass is deployed. Organizations using vulnerable versions of TeamPass face significant risk of data breaches and compliance violations, particularly in environments where the application stores sensitive credentials and authentication information. The vulnerability affects the confidentiality, integrity, and availability of the system, making it a critical concern for security teams managing password vault solutions.
Mitigation strategies for this vulnerability include immediate upgrade to TeamPass version 2.1.27.4 or later, which contains the necessary patches to address the sql injection flaw. Organizations should also implement network segmentation and access controls to limit exposure of the vulnerable application, while monitoring for suspicious activities in authentication logs. Additional defensive measures include implementing web application firewalls, conducting regular security assessments, and ensuring proper input validation throughout the application codebase. The remediation aligns with mitre attack framework techniques that focus on initial access and privilege escalation, making it essential for security teams to address this vulnerability promptly to prevent potential exploitation and maintain system integrity.
