CVE-2024-3116: pgAdmin 4 Remote Code Execution Vulnerability

CVE-2024-3116 Overview

CVE-2024-3116 is a critical Remote Code Execution (RCE) vulnerability affecting pgAdmin 4 versions 8.4 and earlier. The vulnerability exists in the validate binary path API, which allows attackers to execute arbitrary code on the server hosting pgAdmin. This poses a severe risk to database management system integrity and the security of underlying data, as pgAdmin is a widely-used open-source administration and development platform for PostgreSQL databases.

Critical Impact

Successful exploitation enables unauthenticated attackers to execute arbitrary commands on the pgAdmin server, potentially leading to complete system compromise, data theft, and lateral movement within the network.

Affected Products

• pgAdmin 4 versions ≤ 8.4
• Fedora 39 (via packaged pgAdmin)
• Any system running vulnerable pgAdmin 4 installations connected to PostgreSQL databases

Discovery Timeline

• April 4, 2024 - CVE-2024-3116 published to NVD

Technical Details for CVE-2024-3116

Vulnerability Analysis

This Remote Code Execution vulnerability stems from improper handling of user input in pgAdmin's validate binary path API endpoint. The vulnerability is classified under CWE-77 (Command Injection), indicating that the application fails to properly neutralize special elements used in a command before passing user-controlled input to a system shell or command interpreter.

The validate binary path functionality is designed to verify the location of PostgreSQL binaries on the server. However, due to insufficient input validation, an attacker can craft malicious requests that inject arbitrary commands into the path validation process. When the server processes these requests, the injected commands are executed with the privileges of the pgAdmin service account.

The network-accessible nature of this vulnerability means that any pgAdmin instance exposed to untrusted networks is potentially vulnerable. No authentication is required to exploit this vulnerability, and no user interaction is needed, making it particularly dangerous for internet-facing or inadequately segmented pgAdmin deployments.

Root Cause

The root cause is a Command Injection vulnerability (CWE-77) in the validate binary path API. The application fails to properly sanitize or validate user-supplied input before incorporating it into system commands. This allows attackers to break out of the intended command context and inject additional commands that the server will execute.

Attack Vector

The attack is conducted over the network against the pgAdmin web interface. An attacker sends a specially crafted HTTP request to the validate binary path API endpoint, embedding malicious commands within the path parameter. The server-side code processes this input without adequate sanitization, resulting in the execution of the attacker's commands.

The exploitation flow typically involves:

1. Identifying a vulnerable pgAdmin instance accessible over the network
2. Crafting a malicious request to the validate binary path API with injected commands
3. Sending the request to the target server
4. The server executes the injected commands with pgAdmin service privileges

Technical details and proof-of-concept information are available in the GitHub Issue Discussion and the GitHub Gist PoC. Additional analysis is provided in the Vicarius technical writeup.

Detection Methods for CVE-2024-3116

Indicators of Compromise

• Unusual HTTP requests to the pgAdmin validate binary path API endpoint containing shell metacharacters or command sequences
• Unexpected child processes spawned by the pgAdmin web server process
• Anomalous network connections originating from the pgAdmin server to external or internal hosts
• Web server logs showing requests with suspicious path parameters containing characters like ;, |, &, $(), or backticks

Detection Strategies

• Monitor web application logs for requests to the binary path validation endpoint with abnormal parameters
• Implement web application firewall (WAF) rules to detect command injection patterns in HTTP requests
• Deploy endpoint detection and response (EDR) solutions to identify suspicious process execution chains originating from web server processes
• Use network intrusion detection systems (NIDS) to identify exploitation attempts based on known attack signatures

Monitoring Recommendations

• Enable detailed logging for pgAdmin API endpoints and review logs regularly for suspicious activity
• Configure alerting for any process execution by the pgAdmin service user that deviates from normal operational baselines
• Monitor for unexpected outbound network connections from the pgAdmin server
• Implement file integrity monitoring on the pgAdmin installation directory to detect unauthorized modifications

How to Mitigate CVE-2024-3116

Immediate Actions Required

• Upgrade pgAdmin 4 to version 8.5 or later immediately
• Restrict network access to pgAdmin instances, ensuring they are not exposed to untrusted networks or the internet
• Review pgAdmin server logs for evidence of exploitation attempts
• Implement network segmentation to isolate database management tools from general network traffic

Patch Information

The pgAdmin development team has addressed this vulnerability in versions after 8.4. Users should upgrade to pgAdmin 4 version 8.5 or later to remediate this vulnerability. Fedora users should apply updates from the Fedora Package Announcement.

SentinelOne Singularity™ Platform provides protection against exploitation attempts targeting this vulnerability through behavioral AI detection of anomalous command execution patterns and network-based attack detection capabilities.

Workarounds

• Place pgAdmin behind a reverse proxy with strict input validation and WAF rules to filter command injection patterns
• Restrict access to pgAdmin using IP allowlisting or VPN requirements until patching is complete
• Disable or restrict access to the validate binary path API functionality if not operationally required
• Run pgAdmin with minimal privileges to limit the impact of potential exploitation

# Example: Restrict pgAdmin access via firewall (Linux iptables)
# Allow access only from trusted management network
iptables -A INPUT -p tcp --dport 5050 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 5050 -j DROP
