AI-suggested

Upgrade Glances to version 4.5.5 or later, where this vulnerability is fixed. Since the vendor advisory confirms the fix in 4.5.5, applying this update fully mitigates the issue. No additional mitigations are specified.

Description

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.
