CVE-2024-31819 Overview
CVE-2024-31819 is a critical remote code execution vulnerability affecting WWBN AVideo, an open-source video streaming platform. The vulnerability exists in the submitIndex.php component and allows remote attackers to execute arbitrary code by manipulating the systemRootPath parameter. This code injection flaw (CWE-94) enables unauthenticated attackers to gain complete control over vulnerable AVideo installations through network-based attacks.
Critical Impact
This vulnerability allows unauthenticated remote attackers to execute arbitrary code on affected AVideo servers, potentially leading to complete system compromise, data theft, and lateral movement within the network.
Affected Products
- WWBN AVideo versions 12.4 through 14.2
- Self-hosted AVideo streaming platform installations
- Organizations using vulnerable AVideo deployments for video content management

Technical Details for CVE-2024-31819
Vulnerability Analysis
This vulnerability is classified as Code Injection (CWE-94), which occurs when an application improperly constructs code segments using externally-influenced input without proper neutralization. In the context of WWBN AVideo, the submitIndex.php component fails to properly sanitize the systemRootPath parameter before incorporating it into executable code paths.
The vulnerability is particularly dangerous because it requires no authentication and can be exploited remotely over the network. An attacker can craft malicious requests to the vulnerable endpoint, injecting arbitrary code that the server will execute with the privileges of the web application. This represents a complete compromise scenario where attackers can install backdoors, exfiltrate data, or pivot to other systems within the network.
Root Cause
The root cause of CVE-2024-31819 lies in insufficient input validation within the submitIndex.php component. The systemRootPath parameter is accepted from user-controlled input and processed without adequate sanitization or validation. This allows attackers to inject malicious code that is subsequently interpreted and executed by the PHP engine on the server.
The lack of proper input filtering, combined with the direct use of the parameter in a security-sensitive context, creates a straightforward attack vector for code injection.
Attack Vector
The attack is conducted over the network, targeting the submitIndex.php endpoint of vulnerable AVideo installations. An attacker sends a specially crafted HTTP request containing a malicious payload in the systemRootPath parameter.
The vulnerability mechanism involves manipulating the systemRootPath parameter to inject executable code. When the server processes the request, the injected code is executed within the context of the web application.

Detection Methods for CVE-2024-31819
Indicators of Compromise
- Suspicious HTTP requests targeting submitIndex.php with unusual systemRootPath parameter values
- Unexpected PHP process spawning child processes or executing system commands
- New files appearing in web-accessible directories with execution permissions
- Anomalous outbound network connections from the AVideo server
- Modified or newly created PHP files in the AVideo installation directory
Detection Strategies
- Monitor web server access logs for requests to submitIndex.php containing malicious patterns in the systemRootPath parameter
- Implement web application firewall (WAF) rules to detect and block code injection attempts in POST parameters
- Deploy file integrity monitoring on the AVideo installation directory to detect unauthorized modifications
- Configure intrusion detection systems (IDS) to alert on suspicious PHP execution patterns
Monitoring Recommendations
- Enable verbose logging on web servers hosting AVideo and aggregate logs to a SIEM platform
- Monitor for process execution anomalies originating from PHP or web server processes
- Implement network traffic analysis to detect command-and-control communications or data exfiltration
- Regularly audit user accounts and file permissions on AVideo servers for signs of compromise
How to Mitigate CVE-2024-31819
Immediate Actions Required
- Identify all WWBN AVideo installations running versions 12.4 through 14.2 in your environment
- Restrict network access to AVideo instances using firewall rules until patches can be applied
- Review web server logs for evidence of exploitation attempts targeting submitIndex.php
- Consider taking vulnerable instances offline if they are internet-facing and cannot be immediately patched
Patch Information
Organizations should upgrade WWBN AVideo to a version newer than 14.2 that addresses this vulnerability. Check the GitHub WWBN AVideo Project for the latest security releases and patch information. Given the critical severity of this vulnerability and its potential for remote code execution, patching should be treated as an urgent priority.
Workarounds
- Implement WAF rules to block requests containing suspicious patterns in the systemRootPath parameter
- Restrict access to submitIndex.php at the web server level using authentication or IP whitelisting
- Deploy network segmentation to isolate AVideo servers from critical infrastructure
- Monitor and alert on any access attempts to the vulnerable endpoint
# Example: Block access to submitIndex.php using Apache .htaccess
<Files "submitIndex.php">
Order deny,allow
Deny from all
Allow from 192.168.1.0/24
</Files>
