CVE-2025-13505 Overview
CVE-2025-13505 is a Stored Cross-Site Scripting (XSS) vulnerability affecting Datateam Information Technologies Inc. Datactive software. The vulnerability stems from improper neutralization of input during web page generation and improper neutralization of script-related HTML tags. This flaw allows attackers to inject and persist malicious scripts within the application, which are then executed when other users access the affected pages.
Critical Impact
Stored XSS vulnerabilities are particularly dangerous as malicious payloads persist in the application and can affect multiple users. Attackers can steal session cookies, capture credentials, perform actions on behalf of authenticated users, or redirect victims to malicious websites.
Affected Products
- Datateam Information Technologies Inc. Datactive versions from 2.13.34 before 2.14.0.6

Technical Details for CVE-2025-13505
Vulnerability Analysis
This vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). The Datactive application fails to properly sanitize user-supplied input before storing it and subsequently rendering it in web pages. This allows attackers with adjacent network access and low-level privileges to inject malicious JavaScript or HTML content that persists in the application's data store.
The CVSS 3.1 base score is 4.8 (Medium) with the vector string CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. Key characteristics include:
| Metric | Value |
|---|---|
| Attack Vector | Adjacent Network |
| Attack Complexity | Low |
| Privileges Required | Low |
| User Interaction | Required |
| Scope | Changed |
| Confidentiality Impact | Low |
| Integrity Impact | Low |
| Availability Impact | None |
The EPSS (Exploit Prediction Scoring System) score is 0.035% with a percentile of 9.743, indicating a relatively low probability of exploitation in the wild.
Root Cause
The root cause of this vulnerability lies in insufficient input validation and output encoding mechanisms within the Datactive application. When user-supplied data is accepted and stored without proper sanitization, and subsequently displayed without adequate output encoding, it creates an opportunity for Stored XSS attacks. The application fails to neutralize script-related HTML tags, allowing malicious payloads to be preserved and executed in users' browsers.
Attack Vector
The attack vector is classified as Adjacent Network, meaning an attacker must have access to the local network segment where the vulnerable Datactive instance resides. The attacker needs low-level privileges to inject malicious content and requires victim user interaction—specifically, another user must view the page containing the stored malicious payload for the attack to succeed.
A typical attack scenario involves an authenticated attacker submitting malicious JavaScript code through an input field that lacks proper sanitization. When another user views the affected page, the stored script executes in their browser context, potentially allowing the attacker to steal session tokens, modify page content, or perform unauthorized actions on behalf of the victim.

Detection Methods for CVE-2025-13505
Indicators of Compromise
- Unusual JavaScript code or HTML tags appearing in database records or application data fields
- Unexpected script execution errors in browser developer consoles when accessing Datactive pages
- Session anomalies or unauthorized actions traced back to XSS payload execution
- Web application firewall (WAF) logs showing blocked XSS patterns targeting Datactive endpoints
Detection Strategies
Organizations can detect potential exploitation attempts through:
Web Application Firewall (WAF) Rules: Configure WAF to detect and block common XSS patterns including <script> tags, event handlers (onerror, onload, onclick), and JavaScript pseudo-protocols (javascript:).
Log Analysis: Monitor web server and application logs for requests containing HTML or JavaScript injection patterns in parameter values.
Database Monitoring: Implement database activity monitoring to detect stored data containing suspicious script content.
Content Security Policy (CSP) Violations: Deploy and monitor CSP headers to detect unauthorized script execution attempts.
Monitoring Recommendations
Security teams should implement continuous monitoring for:
- HTTP request parameters containing encoded or plaintext script tags
- Changes to stored content that include suspicious HTML elements
- Browser-based security alerts from users accessing the application
- Anomalous user session behavior that may indicate session hijacking following XSS exploitation
SentinelOne Singularity provides advanced threat detection capabilities that can identify malicious script execution patterns and suspicious browser-based activities that may indicate XSS exploitation attempts.
How to Mitigate CVE-2025-13505
Immediate Actions Required
- Upgrade Datateam Datactive to version 2.14.0.6 or later immediately
- Implement Web Application Firewall (WAF) rules to filter XSS payloads targeting Datactive
- Review and sanitize existing stored data for potentially malicious content
- Deploy Content Security Policy (CSP) headers to restrict script execution sources
- Enable HTTP-only and Secure flags on session cookies to limit XSS impact
Patch Information
Datateam Information Technologies Inc. has addressed this vulnerability in Datactive version 2.14.0.6. Organizations running affected versions (from 2.13.34 to versions before 2.14.0.6) should upgrade immediately.
For official patch information and guidance, refer to the USOM advisory (TR-25-0424).
Workarounds
If immediate patching is not possible, organizations should implement the following temporary mitigations:
Input Validation: Implement server-side input validation to reject or encode HTML special characters (<, >, ", ', &) in all user-supplied data.
Output Encoding: Ensure all dynamic content is properly HTML-encoded before rendering in web pages.
Content Security Policy: Deploy restrictive CSP headers to prevent inline script execution.
Network Segmentation: Limit network access to the Datactive application to reduce the adjacent network attack surface.
User Awareness: Educate users about the risks of clicking suspicious links or interacting with unexpected content within the application.
Organizations should prioritize patching to version 2.14.0.6 as the definitive remediation for this vulnerability.
