Channel Manager worker daemon — runs on remote machines to execute video pipeline jobs
AI Security Review
scanned 8d ago · by lpm-firewall-aiThe locator contains a reachable command-injection risk on Windows when an attacker can control the configured user name. This supports a warning, while the inspected source does not establish remote control of that setting or a concrete attack in normal use.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Daemon startup attempts agent resolution when `nst_agent_user` is configured.
Impact
If an attacker can control the local configuration value, commands may run with the worker process’s privileges.
Mechanism
The locator inserts the configured name into a `tasklist` filter without escaping it before executing the command string.
AI rationale
The locator contains a reachable command-injection risk on Windows when an attacker can control the configured user name. This supports a warning, while the inspected source does not establish remote control of that setting or a concrete attack in normal use.
Evidence
bin/cli.jslib/daemon.jslib/nst-agent-locator.js
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI accepts `--nst-user` or a saved value as `nst_agent_user`.
- Daemon startup resolves the configured user’s agent on Windows.
- The locator passes command strings to `execSync`.
- The configured user name is interpolated into the `tasklist` command without escaping.
Evidence against
- The command-injection path requires a crafted local configuration value; inspected source does not show a remote route for changing it.
