Glances has CQL Injection in its Cassandra Export Module via Unsanitized Config Values
Summary
The Cassandra export module (glances/exports/glances_cassandra/__init__.py) interpolates keyspace, table, and replication_factor configuration values directly into CQL statements without validation. A user with write access to glances.conf can redirect all monitoring data to an attacker-controlled Cassandra keyspace.
Vulnerable Code
# Line 80
f"CREATE KEYSPACE {self.keyspace} WITH "
f"replication = {{ 'class': 'SimpleStrategy', 'replication_factor': '{self.replication_factor}' }}"
# Line 94
f"CREATE TABLE {self.table} (plugin text, time timeuuid, stat map<text,float>, PRIMARY KEY (plugin, time)) WITH CLUSTERING ORDER BY (time DESC)"
# Line 112
stmt = f"INSERT INTO {self.table} (plugin, time, stat) VALUES (?, ?, ?)"Steps to Reproduce
- Configure
glances.confwith malicioustablevalue:
[cassandra]
host = 127.0.0.1
port = 9042
keyspace = glances
table = attacker_ks.captured_stats- Create attacker keyspace in Cassandra
- Run
glances --export cassandra - All monitoring data is written to
attacker_ks.captured_statsinstead of the legitimate table
Confirmed output:
INSERT stmt: INSERT INTO attacker_ks.captured_stats (plugin, time, stat) VALUES (?, ?, ?)
Legitimate table row count: 0
Attacker table row count: 1
[CONFIRMED] plugin=cpu, stat={'user': 50.0}Impact
All exported monitoring data (CPU, memory, network, disk I/O) is silently redirected to an attacker-controlled Cassandra keyspace — both data exfiltration and data loss.
Proposed Fix
import re
def _validate_cql_identifier(name: str) -> str:
if not re.match(r'^[a-zA-Z_][a-zA-Z0-9_.]*$', name):
raise ValueError(f"Invalid CQL identifier: {name!r}")
return name
# In __init__(): validate before use
self.keyspace = _validate_cql_identifier(self.keyspace)
self.table = _validate_cql_identifier(self.table)
