  1.1.0

Overview

This appears to be a legitimate J6B/QNX diagnostics skill, but it gives broad root-level device, log-transfer, monitoring, and admin-command guidance without enough scoping or safety warnings.

Install only for authorized J6B/QNX developers, testers, or system operators. Treat logs and coredumps as sensitive, avoid root access unless required by approved procedure, export only necessary files to approved storage, and do not run process-kill, permission-change, time-setting, or background monitoring commands on live systems without explicit operational approval.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands

Findings (12)

Context-Inappropriate Capability

Medium

• Confidence: 84% confidence
• Finding: The skill instructs users to `chmod +x` and launch `/userdata/monitor_cpu.sh` with `nohup`, creating a long-lived background process that persists beyond the immediate analysis session. Even though framed as monitoring, this expands the skill from passive inspection into agentic execution with persistence and ongoing filesystem writes, which can consume resources, leave residue, and operate without continued user awareness.

Vague Triggers

Medium

• Confidence: 88% confidence
• Finding: The trigger list includes many generic troubleshooting terms such as '日志', 'log', 'tail', 'grep', '错误', '异常', '失败', '性能', and 'CPU', which are common across many unrelated tasks. This increases the chance of unintended invocation, causing the skill to surface remote-access, log-download, or monitoring instructions in contexts where the user did not explicitly request this capability.

Missing User Warnings

Medium

• Confidence: 91% confidence
• Finding: The skill provides direct `scp` and `ssh` examples to copy logs from the device to the local machine, including bulk download and tarball creation, but does not warn about sensitive data transfer, storage location, overwrite risk, or local retention. Because logs often contain proprietary, personal, or operationally sensitive information, normalizing unaudited transfer can lead to data exposure or policy violations.

Missing User Warnings

Low

• Confidence: 82% confidence
• Finding: The monitoring section states that the script automatically writes logs under `/userdata/log/cpu_monitor/` and auto-deletes files after 7 days, but it does not clearly warn about disk consumption, log growth, permission requirements, or the operational impact of unattended writes. While lower risk than remote transfer, this can still affect constrained embedded filesystems and surprise operators.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The document explicitly identifies log and coredump locations and says important logs should be downloaded promptly, but it does not warn that these artifacts may contain sensitive diagnostic, crash, filesystem, process, or proprietary system information. In a vehicle/embedded troubleshooting skill, that omission increases the chance of unauthorized collection, mishandling, or over-sharing of sensitive data during support workflows.

Missing User Warnings

Medium

• Confidence: 97% confidence
• Finding: The skill provides ready-to-run ssh/scp commands to copy logs from a device to another machine, including bulk collection of all module logs, without any warning about authorization, privacy review, secure destination handling, or credential hygiene. Because these commands facilitate direct exfiltration of operational and crash data from an embedded system, the skill context makes the omission more dangerous than generic documentation.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The document includes QNX process-termination commands such as `slay <PID>`, `slay -f <PID>`, and killing by process name, but provides no warning that these actions can abruptly stop critical vehicle or system services. In a log-analysis/troubleshooting skill, users are likely to copy commands directly, so omission of impact guidance materially increases the chance of accidental service disruption or unsafe system state changes.

Missing User Warnings

Medium

• Confidence: 97% confidence
• Finding: The skill documents `su -`, `sudo command`, `chmod`, and `chown` examples without warning that elevated privileges and recursive permission changes can alter system integrity, expose logs, or break applications. Because this skill is explicitly for operational troubleshooting on a QNX board, operators may run these commands on live systems, making unintended privilege misuse or permission damage more plausible.

Missing User Warnings

Low

• Confidence: 88% confidence
• Finding: The document shows `date -s` for setting system time without noting that changing time can skew logs, interfere with diagnostics, disrupt scheduled tasks, and affect security mechanisms that rely on timestamps. While lower impact than process termination or privilege escalation, it can still compromise forensic accuracy and operational behavior during troubleshooting.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The troubleshooting section recommends killing a problematic process as a routine response to process anomalies, but does not warn about service interruption, cascading failures, or loss of volatile diagnostic context. In this skill's troubleshooting context, prescriptive operational steps are likely to be followed quickly, which makes the missing warning more dangerous than in a purely academic reference.

Missing User Warnings

Medium

• Confidence: 91% confidence
• Finding: The guide explicitly tells users to download and back up important logs locally, but it does not warn that logs can contain sensitive vehicle, system, environment, or user-related data. In a log-analysis skill, this omission increases the chance of uncontrolled data export, insecure storage, or sharing of sensitive diagnostic artifacts outside approved handling processes.

Missing User Warnings

Medium

• Confidence: 89% confidence
• Finding: The manual provides concrete SSH/SCP access patterns, host IPs, and a root username, but gives no warning about credential handling, least privilege, log sensitivity, or authorization checks before export. In an agent skill context, this can normalize unsafe remote access and data exfiltration workflows, increasing the chance that operators expose sensitive logs or use overly privileged accounts without review.
