CVE-2022-24856 is a Server-Side Request Forgery (SSRF) vulnerability affecting FlyteConsole, the web user interface component of the Flyte platform, prior to version 0.52.0. FlyteConsole is designed to provide users with a graphical interface to interact with Flyte's workflow orchestration capabilities. The vulnerability arises due to the presence of a 'cors_proxy' feature that improperly handles requests, allowing an attacker who can induce a user to interact with a vulnerable FlyteConsole instance exposed to the internet to make the server perform unauthorized HTTP requests. Specifically, an attacker can exploit any authenticated or unauthenticated user session to send requests from the FlyteConsole server to internal resources such as metadata servers or other internal endpoints that are typically inaccessible externally. This can lead to unauthorized access to sensitive internal services and potentially the leakage of internal headers or metadata. The vulnerability does not require direct authentication by the attacker but leverages user interaction with the vulnerable interface. The patch for this issue, introduced in FlyteConsole version 0.52.0, removes the 'cors_proxy' functionality entirely, as it is no longer necessary for the console's operation. Until the patch is applied, a recommended mitigation is to disable FlyteConsole's exposure to the public internet, restricting access to trusted internal networks only. No known exploits have been reported in the wild, but the vulnerability's nature makes it a significant risk if the console is publicly accessible without proper controls.

For European organizations using FlyteConsole versions prior to 0.52.0, this SSRF vulnerability poses a risk of unauthorized internal network reconnaissance and potential data exposure. Attackers could leverage this flaw to access internal metadata services or other unauthenticated internal endpoints, which may contain sensitive configuration or operational data. This could facilitate further lateral movement or targeted attacks within the organization's infrastructure. The impact on confidentiality is moderate to high depending on the sensitivity of the internal services exposed. Integrity and availability impacts are lower but could arise if internal services are manipulated or overwhelmed via SSRF. Given Flyte's use in data orchestration and workflow management, disruption or compromise could affect critical data processing pipelines, impacting business operations. The risk is heightened for organizations that expose FlyteConsole directly to the internet without network segmentation or access controls. European organizations in sectors such as finance, healthcare, and critical infrastructure that rely on Flyte for data workflows are particularly at risk due to the potential exposure of sensitive internal services and data.

1. Immediate upgrade to FlyteConsole version 0.52.0 or later to apply the official patch that removes the vulnerable 'cors_proxy' functionality. 2. Until patching is possible, restrict FlyteConsole access to internal networks only; disable public internet exposure via firewall rules or VPN access. 3. Implement strict network segmentation to isolate FlyteConsole servers from sensitive internal metadata and management services. 4. Monitor network traffic from FlyteConsole servers for unusual outbound requests indicative of SSRF exploitation attempts. 5. Review and harden internal metadata and management endpoints to require authentication and limit access scope. 6. Educate users on the risks of interacting with FlyteConsole instances exposed externally and encourage reporting of suspicious behavior. 7. Conduct regular security assessments and penetration testing focusing on SSRF and related web interface vulnerabilities in FlyteConsole deployments.
