DataEase - Authentication Bypass (CVE-2024-56511)

CVE-2024-56511 is a critical authentication bypass vulnerability in DataEase versions before 2.10.4. Attackers can exploit URL path manipulation involving configured context paths to evade whitelist-based authentication checks and access protected interfaces without credentials, potentially leading to unauthorized data access, modification, or full application compromise.

CrowdSec has been tracking this vulnerability and its exploits since 3rd of August 2026.

CrowdSec network observations suggest that most exploitation of CVE-2024-56511 involves focused reconnaissance to identify viable targets. Attackers typically tailor their campaigns based on system exposure and configuration. It is unlikely that a given attack is accidental. CrowdSec network telemetry also shows that exploitation of CVE-2024-56511 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit the authentication bypass by requesting protected DataEase endpoints with a whitelisted prefix followed by ../, such as /geo/../de2api/datasource/types. Detection should focus on traversal patterns targeting /de2api/, particularly datasource, user-management, dashboard, and export endpoints, alongside unexpected unauthenticated JSON responses.
