CVE-2019-7352 in ZoneMinder
Summary
by MITRE
Self - Stored Cross Site Scripting (XSS) exists in ZoneMinder through 1.32.3, as the view 'state' (aka Run State) (state.php) does no input validation to the value supplied to the 'New State' (aka newState) field, allowing an attacker to execute HTML or JavaScript code.

The vulnerability identified as CVE-2019-7352 represents a critical self-stored cross site scripting flaw within ZoneMinder version 1.32.3 and earlier. This vulnerability resides in the state.php web page component which manages the Run State functionality of the surveillance system. The flaw occurs when the application fails to properly validate or sanitize user input supplied to the 'New State' parameter, creating an opportunity for malicious actors to inject persistent HTML or JavaScript code into the application's state management system. The vulnerability is classified as self-stored XSS because the malicious payload is stored within the application's database or configuration files and subsequently executed when other users access the affected state management interface.
The technical exploitation of this vulnerability follows the standard XSS attack pattern where an attacker crafts malicious input containing script code and submits it through the vulnerable newState parameter. When the ZoneMinder application processes this input without proper sanitization, the malicious code becomes permanently stored within the system's state records. Subsequent access to the state.php page by other users triggers the execution of this stored malicious code within their browser context, potentially leading to session hijacking, credential theft, or redirection to malicious websites. This vulnerability directly maps to CWE-79, which defines Cross-Site Scripting as a weakness where untrusted data is incorporated into web page content without proper validation or escaping mechanisms.
The operational impact of this vulnerability extends beyond simple script execution, as it compromises the integrity and security of the entire ZoneMinder surveillance platform. An attacker with access to the application's administrative or user interfaces could leverage this vulnerability to gain persistent access to the surveillance system, potentially leading to unauthorized monitoring activities or complete system compromise. The self-stored nature of the vulnerability means that the malicious code remains active even after the initial injection, creating a persistent threat that could go unnoticed for extended periods. This flaw particularly affects organizations relying on ZoneMinder for security monitoring, as it undermines the trustworthiness of the system's state management and could be exploited to manipulate surveillance operations or hide malicious activities within the system's configuration.
Effective mitigation strategies for CVE-2019-7352 require immediate implementation of input validation and output sanitization measures within the ZoneMinder application. Organizations should upgrade to ZoneMinder version 1.32.4 or later, which includes proper input validation for the newState parameter. Additionally, administrators should implement proper content security policies and input sanitization routines that escape or filter all user-supplied data before storage. The remediation efforts should follow ATT&CK technique T1059.007 for defense against script injection attacks, while also implementing proper web application firewall rules to detect and block malicious payloads targeting the state.php endpoint. Regular security audits of web application inputs and outputs should be conducted to identify similar vulnerabilities in other components of the surveillance system, as this type of flaw often indicates broader input validation weaknesses within the application architecture.
