Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances XML-RPC server (glances -s, implemented in glances/server.py) does not validate the HTTP Host header, leaving it vulnerable to DNS rebinding attacks. An attacker can exploit DNS rebinding to exfiltrate the full system monitoring dataset from a victim's browser. This vulnerability is fixed in 4.5.5.
