CVE-2024-26479: Statping-ng Information Disclosure Flaw

CVE-2024-26479 Overview

CVE-2024-26479 is an information disclosure vulnerability affecting Statping-ng, an open-source status page and monitoring system. The vulnerability exists in version 0.91.0 and allows an attacker to obtain sensitive information via a crafted request to the Command execution function. This flaw enables unauthorized access to confidential data that should not be exposed to external parties.

Critical Impact

Attackers can extract sensitive system information through the Command execution function without authentication, potentially exposing internal configuration details and system data.

Affected Products

• Statping-ng v.0.91.0

Technical Details for CVE-2024-26479

Vulnerability Analysis

This vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The flaw resides in the Command execution function within Statping-ng, which fails to properly restrict access to sensitive information. When exploited, an attacker can craft malicious requests that trigger the vulnerable function and retrieve confidential data that would otherwise be protected.

The vulnerability is accessible over the network without requiring user interaction or prior authentication. While the impact is limited to confidentiality (no integrity or availability impact), the exposed information could be leveraged for further attacks against the monitoring infrastructure or the systems it monitors.

Root Cause

The root cause of this vulnerability stems from improper access controls in the Command execution function. Statping-ng fails to adequately validate and sanitize incoming requests before processing them, allowing specially crafted inputs to bypass security mechanisms and expose sensitive information. The lack of proper authorization checks on this endpoint enables unauthenticated attackers to extract data that should only be accessible to authenticated administrators.

Attack Vector

The attack vector is network-based, requiring the attacker to send crafted HTTP requests to the vulnerable Statping-ng instance. The exploitation requires no special privileges and does not depend on user interaction. An attacker with network access to the Statping-ng application can target the Command execution function endpoint with malicious requests designed to extract sensitive information.

The attack can be performed remotely against any exposed Statping-ng instance running the vulnerable version. Organizations running Statping-ng as a public-facing status page are particularly at risk, as the application is designed to be accessible to external users.

Technical details and proof-of-concept materials are available in the GitHub PoC Repository.

Detection Methods for CVE-2024-26479

Indicators of Compromise

• Unusual or malformed HTTP requests targeting the Command execution endpoint
• Unexpected data extraction patterns in application logs
• Anomalous traffic patterns to the Statping-ng monitoring interface from unknown sources
• Log entries showing access attempts to sensitive configuration or system information endpoints

Detection Strategies

• Monitor HTTP access logs for crafted requests targeting the Command execution function
• Implement web application firewall (WAF) rules to detect and block malicious request patterns
• Set up alerts for abnormal access patterns to the Statping-ng application
• Deploy network intrusion detection systems (NIDS) to identify exploitation attempts

Monitoring Recommendations

• Enable verbose logging on the Statping-ng application to capture detailed request information
• Monitor for unusual response sizes that may indicate successful data extraction
• Implement rate limiting on the affected endpoints to slow potential exploitation
• Review access logs regularly for indicators of reconnaissance or exploitation activity

How to Mitigate CVE-2024-26479

Immediate Actions Required

• Identify all Statping-ng v.0.91.0 instances in your environment
• Restrict network access to Statping-ng to trusted IP addresses only
• Place Statping-ng behind a reverse proxy with authentication requirements
• Monitor for any signs of exploitation while awaiting an official patch

Patch Information

At the time of publication, no official patch has been released by the Statping-ng maintainers. Organizations should monitor the Statping NG GitHub Repository for security updates and new releases that address this vulnerability. Consider implementing the workarounds below until an official fix becomes available.

Workarounds

• Implement network-level access controls to restrict who can reach the Statping-ng instance
• Deploy a web application firewall (WAF) to filter malicious requests before they reach the application
• Use a reverse proxy with authentication to add an additional security layer
• Consider temporarily disabling the Command execution functionality if not critical to operations

# Example: Restrict access to Statping-ng using iptables
# Allow only trusted networks to access the application
iptables -A INPUT -p tcp --dport 8080 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -s 192.168.0.0/16 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
