CVE-2025-11962: Digital Corporate Warehouse XSS Flaw

CVE-2025-11962 Overview

CVE-2025-11962 is a stored Cross-Site Scripting (XSS) vulnerability affecting DivvyDrive Information Technologies Inc. Digital Corporate Warehouse. The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. An authenticated attacker can inject malicious script content that persists on the server and executes in the browsers of users who later view the affected pages. Successful exploitation can lead to session theft, account compromise, and unauthorized actions performed in the context of the victim user. The vulnerability affects all Digital Corporate Warehouse versions before v.4.8.2.22.

Critical Impact
Authenticated attackers can store malicious JavaScript that executes in other users' browsers, enabling session hijacking and unauthorized actions within the corporate document repository.

Affected Products

DivvyDrive Digital Corporate Warehouse versions before v.4.8.2.22
All deployments storing user-supplied content without proper output encoding
Web interfaces rendering attacker-controlled fields back to other authenticated users

Technical Details for CVE-2025-11962

Vulnerability Analysis

The vulnerability is a stored XSS flaw in the Digital Corporate Warehouse web application. The application accepts user-supplied input and stores it in backend storage without sufficient sanitization or output encoding. When other users load views that render this stored content, the browser interprets the injected payload as executable script. Because the payload is persistent, every visitor to the affected page becomes a target until the malicious content is removed. Exploitation requires low privileges and user interaction, but the impact on confidentiality and integrity is high. Attackers can hijack authenticated sessions, exfiltrate documents accessible to the victim, and perform privileged actions through forged in-browser requests.

Root Cause

The root cause is improper neutralization of input during web page generation [CWE-79]. The application fails to apply context-aware output encoding when reflecting stored user-controlled data into HTML, attribute, or JavaScript contexts. Server-side input validation and HTML entity encoding routines are either missing or insufficient for the fields exposed to attacker control.

Attack Vector

The attack vector is network-based and requires a low-privileged authenticated account. An attacker submits a crafted payload through an input field that is later rendered to other users. When a victim browses the affected page, the stored script executes under the victim's session origin. See the Siber Güvenlik Advisory TR-25-0393 and USOM Notification TR-25-0393 for the official advisory details.

Detection Methods for CVE-2025-11962

Indicators of Compromise

Stored field values containing HTML tags such as <script>, <img onerror=>, or <svg onload=> in document metadata, comments, or descriptive fields.
Outbound HTTP requests from user browsers to unfamiliar domains shortly after loading Digital Corporate Warehouse pages.
Unexpected session token or cookie transmissions originating from authenticated user sessions.
Anomalous account activity following document or page views, including privilege changes or document downloads from unusual locations.

Detection Strategies

Review web server access logs for POST or PUT requests containing HTML or JavaScript syntax in body parameters submitted to Digital Corporate Warehouse endpoints.
Deploy Content Security Policy (CSP) violation reporting to surface injected inline scripts attempting to execute in user browsers.
Scan stored database fields for known XSS payload patterns and HTML control characters in fields intended to be plain text.

Monitoring Recommendations

Monitor authentication and session activity for concurrent logins or impossible-travel events that may indicate session theft.
Alert on outbound network connections from user workstations to newly registered or low-reputation domains following Digital Corporate Warehouse access.
Track administrative actions performed shortly after a user viewed content authored by a lower-privileged account.

How to Mitigate CVE-2025-11962

Immediate Actions Required

Upgrade Digital Corporate Warehouse to version v.4.8.2.22 or later as the primary remediation.
Audit existing stored content for embedded HTML or script payloads and purge any malicious entries.
Invalidate active sessions and force re-authentication after applying the patch to revoke any tokens captured during exploitation.
Review account permissions and remove unnecessary write access from low-trust users.

Patch Information

DivvyDrive Information Technologies Inc. addressed the vulnerability in Digital Corporate Warehouse v.4.8.2.22. Administrators should consult the Siber Güvenlik Advisory TR-25-0393 for vendor-supplied remediation guidance and apply the upgrade across all production and staging instances.

Workarounds

Restrict write access to fields that render in shared views until the patch is applied.
Deploy a strict Content Security Policy that blocks inline scripts and unauthorized script sources to limit payload execution.
Place the application behind a Web Application Firewall (WAF) with rules to filter HTML and JavaScript syntax from form submissions.
Educate users to report unexpected browser behavior, popups, or redirects when accessing the warehouse interface.
