CVE-2019-25270 Overview
SOCA Access Control System version 180612 contains a cross-site scripting (XSS) vulnerability in the senddata POST parameter of logged_page.php. This flaw allows attackers to inject malicious scripts by sending crafted POST requests, which can then execute arbitrary HTML and script code within a victim's browser session. When exploited, an attacker can potentially steal session cookies, perform actions on behalf of authenticated users, or redirect users to malicious websites.
Critical Impact
Attackers can execute arbitrary JavaScript in authenticated user sessions, potentially leading to session hijacking, credential theft, or unauthorized actions within the SOCA Access Control System.
Affected Products
- SOCA Access Control System version 180612

Technical Details for CVE-2019-25270
Vulnerability Analysis
This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting (XSS). The flaw resides in the logged_page.php file within the SOCA Access Control System, specifically in how the application handles the senddata POST parameter.
The application fails to properly sanitize or encode user-supplied input before reflecting it back in the rendered web page. This lack of input validation allows malicious actors to inject arbitrary HTML and JavaScript code that executes within the security context of the vulnerable application.
Root Cause
The root cause of this vulnerability is insufficient input validation and output encoding in the logged_page.php script. When processing POST requests containing the senddata parameter, the application directly incorporates user-supplied data into the HTML response without proper sanitization. This violates secure coding principles that require all untrusted input to be validated, sanitized, and properly encoded before being included in web page output.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker can exploit this vulnerability by crafting a malicious POST request containing JavaScript code in the senddata parameter. The attack typically involves:
- The attacker crafts a malicious form or request that submits attacker-controlled JavaScript through the senddata parameter
- A victim user with an active session is tricked into submitting this request (via social engineering or a malicious page)
- The vulnerable logged_page.php script processes the request and reflects the malicious script in the response
- The victim's browser executes the injected script within the context of the SOCA Access Control System session
The vulnerability allows execution of arbitrary scripts in the victim's browser, potentially enabling session hijacking, cookie theft, keylogging, or defacement of the application interface. For detailed technical information, refer to the ZeroScience Vulnerability ZSL-2019-5518 advisory.
Detection Methods for CVE-2019-25270
Indicators of Compromise
- Unusual POST requests to logged_page.php containing script tags or JavaScript event handlers in the senddata parameter
- Web server logs showing encoded script content (e.g., %3Cscript%3E) in POST parameters
- Browser-based security alerts triggered by inline script execution policies
- Unexpected session behavior or unauthorized actions in user accounts
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block XSS payloads in POST parameters
- Enable Content Security Policy (CSP) headers to prevent execution of inline scripts
- Monitor web server access logs for suspicious patterns in the senddata parameter
- Deploy endpoint detection solutions that can identify browser-based exploitation attempts
Monitoring Recommendations
- Enable detailed logging for all requests to logged_page.php and monitor for anomalous input patterns
- Configure security information and event management (SIEM) alerts for XSS attack signatures
- Implement real-time monitoring of authentication events to detect potential session hijacking
How to Mitigate CVE-2019-25270
Immediate Actions Required
- Restrict access to the SOCA Access Control System to trusted networks only until a patch is available
- Implement Web Application Firewall (WAF) rules to filter XSS payloads targeting the senddata parameter
- Deploy Content Security Policy (CSP) headers to mitigate the impact of successful XSS attacks
- Educate users about the risks of clicking on suspicious links or submitting untrusted forms
Patch Information
No official vendor patch has been identified in the available vulnerability data. Organizations should contact SocaTech directly to inquire about security updates for the SOCA Access Control System. Additional technical details are available from CXSecurity Issue WLB-2019050151, IBM X-Force Vulnerability #160976, and Packet Storm Security File #152837.
Workarounds
- Implement server-side input validation and output encoding for the senddata parameter in logged_page.php
- Deploy a reverse proxy or WAF with XSS filtering capabilities in front of the application
- Restrict access to the SOCA Access Control System using network segmentation and firewall rules
- Enable HTTPOnly and Secure flags on session cookies to reduce the impact of potential session theft
