CVE-2025-1987 in SecurePass
Summary
by MITRE • 06/21/2025
A Cross-Site Scripting (XSS) vulnerability has been identified in Psono-Client’s handling of vault entries of type website_password and bookmark, as used in Bitdefender SecurePass. The client does not properly sanitize the URL field in these entries. As a result, an attacker can craft a malicious vault entry (or trick a user into creating or importing one) with a javascript:URL. When the user interacts with this entry (for example, by clicking or opening it), the application will execute the malicious JavaScript in the context of the Psono vault. This allows an attacker to run arbitrary code in the victim’s browser, potentially giving them access to the user’s password vault and sensitive data.

This cross-site scripting vulnerability exists within the Psono-Client component of Bitdefender SecurePass, specifically affecting how the application processes vault entries of type website_password and bookmark. The flaw stems from insufficient input validation and sanitization of URL fields in these entry types, creating a persistent security weakness that can be exploited through maliciously crafted vault entries. The vulnerability represents a classic XSS attack vector where attacker-controlled JavaScript code can be executed within the context of the legitimate user's browser session, effectively bypassing normal security boundaries that protect the password vault environment.
The technical implementation of this vulnerability occurs when the client application fails to properly sanitize or escape URL values before rendering them in the user interface. When a malicious user creates or imports a vault entry containing a javascript:URL scheme in the URL field, the application processes this unvalidated input without adequate protection mechanisms. This allows the attacker to inject malicious JavaScript code that executes whenever the user interacts with the compromised entry through normal operations such as clicking or opening the entry. The execution context provides the attacker with the ability to manipulate the victim's browser session, potentially accessing sensitive data stored within the password vault and executing arbitrary commands within the application's security boundaries.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with comprehensive access to the user's password vault and associated sensitive information. An attacker who successfully exploits this vulnerability can potentially exfiltrate stored passwords, personal information, and other confidential data from the vault. The attack requires minimal user interaction beyond normal application usage, making it particularly dangerous as it can be triggered through legitimate user activities such as opening bookmark entries or navigating through website password entries. This vulnerability essentially transforms the user's own password manager into an attack vector, undermining the fundamental security assumptions of password management applications.
Security mitigations for this vulnerability should focus on implementing robust input validation and sanitization mechanisms for all URL fields within vault entries. The application must sanitize URL inputs to remove or escape potentially dangerous schemes such as javascript:, data:, and vbscript: before rendering them in the user interface. Additionally, implementing Content Security Policy (CSP) headers and using proper output encoding techniques can provide defense-in-depth measures against XSS exploitation. Organizations should also consider implementing automatic scanning and validation of imported vault entries to detect and prevent malicious content from entering the system. This vulnerability aligns with CWE-79 which specifically addresses Cross-Site Scripting flaws, and represents a technique that could be categorized under ATT&CK tactic TA0001 (Initial Access) and technique T1059.007 (Command and Scripting Interpreter: JavaScript) in the MITRE ATT&CK framework.
