bash ps auxbash netstat -tulpnbash ss -tulnbash lsmodbash printenv env setbash iptables -L ufw status verbose firewall-cmd --list-all pfctl -s rulesTechnical Analysis
The skill presents broad system-enumeration commands as general listing operations without requiring explicit authorization, limiting collection to task-relevant information, or providing output-redaction safeguards.
In particular,
printenv,env, and shellsetcan disclose sensitive runtime values such as API keys, access tokens, credentials, proxy secrets, service endpoints, and shell functions. Thesetcommand can expose more information than environment-only commands because it may include shell-local variables and function definitions.The process, listening-port, kernel-module, and firewall commands disclose detailed host-security topology. Depending on operating-system permissions, commands such as
netstat -tulpn,iptables -L, andpfctl -s rulesmay also reveal privileged process associations or security policy details. The document does not itself bypass permissions or execute these commands automatically, but its broad trigger and lack of least-privilege constraints can cause an agent to collect substantially more sensitive information than a routine file-listing request requires.Attack Path
- A user or untrusted prompt invokes the broadly described listing skill.
- The agent interprets the request as authorization to inspect general system state.
- The agent runs commands such as
printenv,set,ps aux,netstat -tulpn, or firewall-rule enumeration. - Cred ...[truncated 1529 chars]

Remediation Suggestions
- Remove
printenv,env, andsetfrom general-purpose listing guidance. Provide targeted alternatives that display only explicitly requested, non-sensitive variable names. - Require explicit informed confirmation before enumerating environment variables, all processes, process-to-port mappings, kernel modules, routing information, or firewall rules.
- Apply least-privilege defaults. File-listing requests should run only file-listing commands and must not implicitly authorize broader host reconnaissance.
- Introduce a strict allowlist of safe commands and options for each supported intent.
- Redact values whose names match secret patterns such as
TOKEN,SECRET,PASSWORD,PASS,KEY,CREDENTIAL,AUTH, andCOOKIE. - Return only task-relevant fields. For example, omit process command-line arguments and process ownership unless the user explicitly requests them.
- Avoid privileged execution and clearly state that the skill must not use
sudo, elevation, or permission bypasses to obtain otherwise inaccessible details. - Prevent sensitive command output from being retained in persistent memory, telemetry, or logs.
- Document trust boundaries and warn that system-enumeration output may contain confidential information that should not be shared with third parties.
