0.17.1
CVE-2024-31461 describes a Server-Side Request Forgery (SSRF) vulnerability affecting Plane, an open-source project management tool. This flaw allows attackers to initiate requests from the server hosting the application, potentially granting unauthorized access to internal resources. Versions prior to 0.17-dev are vulnerable, and a patch is included in version 0.17-dev.
The SSRF vulnerability in Plane allows an attacker to leverage the application server as a proxy to interact with internal services that are not directly accessible from the outside world. This can lead to unauthorized access to sensitive data stored within those internal systems, such as configuration files, database credentials, or API keys. Furthermore, an attacker could potentially manipulate internal APIs or trigger unintended actions within the internal network. The blast radius extends to any internal service accessible from the Plane server, potentially compromising the entire internal infrastructure.
CVE-2024-31461 was publicly disclosed on April 10, 2024. While no active exploitation campaigns have been publicly reported, the SSRF nature of the vulnerability makes it a potential target for opportunistic attackers. The vulnerability's CRITICAL severity score indicates a high potential for exploitation. It is not currently listed on the CISA KEV catalog.
Organizations using Plane for project management, particularly those with sensitive internal services accessible from the application server, are at risk. Shared hosting environments where Plane is deployed alongside other applications are also vulnerable, as a compromised Plane instance could potentially be used to access other hosted services.
• linux / server: Monitor Plane application logs for unusual outbound requests to internal services. Use journalctl -u plane to filter for HTTP requests to unexpected destinations.
journalctl -u plane | grep -i 'http://internal.service/'• generic web: Use curl to test for SSRF by attempting to access internal services through the Plane application.
curl http://localhost:8080/internal_service• windows / supply-chain: If Plane is running within a container on Windows, monitor container logs for suspicious outbound connections using PowerShell's Get-NetTCPConnection.

The primary mitigation for CVE-2024-31461 is to upgrade Plane to version 0.17-dev or later, which includes the necessary patch. If upgrading immediately is not feasible, consider implementing a Web Application Firewall (WAF) with strict outbound request filtering rules to block suspicious URLs and protocols. Additionally, restrict the network access of the Plane server to only the necessary internal services. Carefully review and validate all user inputs to prevent attackers from injecting malicious URLs. After upgrading, confirm the fix by attempting to access an internal service through the Plane application and verifying that the request is blocked or properly handled.
Actualice a la versión 0.17-dev o posterior. Si no puede actualizar inmediatamente, restrinja las conexiones de red salientes del servidor que aloja la aplicación solo a los servicios esenciales. Implemente una validación estricta de las URL o parámetros que se utilizan para generar solicitudes del lado del servidor.
