Vulnerability details
The vulnerability allows a low-privileged authenticated attacker to originate network probes from another tenant's managed server using that tenant's stored SSH credentials.
The vulnerability exists due to missing server ownership authorization in Roxy-WI's /nettools/* POST handlers when processing the user-controlled server_from parameter. A low-privileged authenticated attacker can supply another tenant's managed server IP with working stored SSH credentials to execute constrained network diagnostics and retrieve results from that server's network.
