CVE-2025-13505 Overview
CVE-2025-13505 is a stored Cross-Site Scripting (XSS) vulnerability affecting Datateam Information Technologies Inc. Datactive. The flaw results from improper neutralization of input during web page generation, allowing attackers to inject script-related HTML tags that persist within the application [CWE-79]. When another user renders the affected page, the stored payload executes in the victim's browser under the origin of the Datactive application.
The vulnerability affects Datactive versions from 2.13.34 before 2.14.0.6. Exploitation requires user interaction but does not require prior authentication or elevated privileges.
Critical Impact
Attackers can inject persistent JavaScript that executes in the browsers of authenticated users, enabling session data theft, unauthorized actions, and cross-user compromise within Datactive deployments.
Affected Products
- Datateam Datactive 2.13.34 through versions before 2.14.0.6
- Web applications and portals built on affected Datactive releases
- Downstream integrations that render Datactive-managed content without additional sanitization

Technical Details for CVE-2025-13505
Vulnerability Analysis
The vulnerability is a stored XSS issue in Datactive. The application accepts user-supplied input and persists it to backend storage without adequate neutralization of HTML control characters or <script>-related tags. When the stored content is later rendered into an HTML response, the browser interprets the attacker-controlled markup as executable script rather than inert data.
Because the payload is stored server-side, every user who visits the affected view receives the malicious script. This differs from reflected XSS in that no crafted link is required for repeated exploitation. The scope-changed CVSS metric indicates the injected script can affect resources beyond the vulnerable component, including other browser contexts sharing the origin.
Root Cause
Datactive fails to apply context-appropriate output encoding when writing user input into HTML responses. Input fields that should be treated as plain text are rendered without HTML entity encoding, allowing tags such as <script>, <img onerror=...>, and event-handler attributes to survive intact. The absence of a strict Content Security Policy (CSP) compounds the issue by permitting inline script execution.
Attack Vector
An unauthenticated attacker submits a crafted payload through an input field that Datactive stores and later renders in a web page. A legitimate user, typically an administrator or operator, subsequently loads the page containing the stored payload. The browser parses the injected markup and executes the attacker's JavaScript in the user's session context.
Common post-exploitation actions include exfiltrating session cookies, issuing authenticated requests against the Datactive backend on behalf of the victim, capturing keystrokes, and delivering secondary payloads through the trusted origin. See the USOM Notification TR-25-0424 for vendor-coordinated advisory details.
Detection Methods for CVE-2025-13505
Indicators of Compromise
- Datactive database records containing <script>, javascript:, or HTML event handler attributes such as onerror= and onload= inside fields intended for plain text.
- Outbound HTTP requests from user browsers to unfamiliar domains immediately after loading Datactive pages.
- Unexpected session token usage from IP addresses that do not match the authenticated user's normal location.
Detection Strategies
- Review Datactive application logs for POST or PUT requests containing HTML tags, encoded angle brackets (%3Cscript%3E), or JavaScript URI schemes in body parameters.
- Deploy web application firewall (WAF) rules that flag script-related tokens submitted to Datactive input endpoints.
- Correlate browser Content Security Policy violation reports with Datactive page loads to surface active injection attempts.
Monitoring Recommendations
- Monitor Datactive user activity for anomalous privilege changes, password resets, or configuration updates that occur shortly after a session loads a suspect page.
- Track outbound network traffic from workstations accessing Datactive for connections to newly registered or low-reputation domains.
- Alert on Datactive administrator sessions issuing bulk API calls that do not align with typical workflow patterns.
How to Mitigate CVE-2025-13505
Immediate Actions Required
- Upgrade Datactive to version 2.14.0.6 or later on all deployments.
- Audit stored Datactive content for embedded script tags or event handlers and remove malicious entries before returning the application to production use.
- Rotate session tokens and administrative credentials for any user who accessed the application during the exposure window.
Patch Information
Datateam addresses CVE-2025-13505 in Datactive 2.14.0.6. Administrators should apply the vendor-supplied release across all instances. Refer to the Siber Guvenlik Bulletin TR-25-0424 and the USOM Notification TR-25-0424 for authoritative version and remediation information.
Workarounds
- Deploy a WAF policy in front of Datactive that blocks HTML tags and JavaScript URI schemes in request parameters until the patch is applied.
- Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins.
- Restrict Datactive access to authenticated users on trusted networks to reduce the population of potential injectors during the remediation window.
