Vulnerability Type: Privileged access to raw system memory
Risk Level: HighVulnerable Code Snippet:
bash # /dev/mem (limited, requires permissions) sudo dd if=/dev/mem of=memory.raw bs=1M # /proc/kcore (ELF format) sudo cp /proc/kcore memory.elfTechnical Analysis
The Skill instructs the Agent to use
sudoto copy data from/dev/memor/proc/kcore. These interfaces may expose kernel memory and the memory of user processes. A resulting image can contain passwords, cryptographic keys, access tokens, application secrets, personal information, and other security-sensitive data.Raw memory acquisition is a legitimate forensic capability, but the Skill does not require the Agent to verify authorization, establish an approved scope, minimize collected data, or apply secure evidence-handling controls before executing these privileged commands. Consequently, an Agent following the instructions could cross least-privilege boundaries when the underlying task has not explicitly authorized full-system memory acquisition.
Attack Path
- An attacker or untrusted user submits a request framed as a memory-forensics task.
- The Agent follows the Skill and requests or uses elevated privileges.
- The Agent reads
/dev/memor/proc/kcoreand creates a memory image. - The image is searched for credentials, tokens, keys, or data belonging to other users and processes.
- The extracted material is used to access protected applications, accounts, or services.
Exploitation depends on the Agent having, or being able to obtain, sufficient operating-system privileges.
Impact Assessment
Successful exploitation may disclose memory belonging to the kernel and multiple local processes. Depending on the host and available memory interface, the exposed scope can include credentials, session tokens, encryption keys, confidential docum ...[truncated 195 chars]

Remediation Suggestions
- Require explicit confirmation that the requester owns or is authorized to examine the target system.
- Define the target host, investigation scope, evidence destination, retention period, and approved acquisition method before running privileged commands.
- Require a human approval checkpoint before invoking
sudoor reading kernel memory interfaces. - Prefer a reviewed acquisition utility that records acquisition metadata and minimizes changes to the target.
- Write evidence only to an encrypted, access-controlled destination rather than a general temporary directory.
- Calculate and record a cryptographic hash immediately after acquisition.
- Record the operator, date, tool version, command, target, and evidence hash for chain-of-custody purposes.
- Prevent memory images from being uploaded, shared, or transmitted without separate authorization.
- Securely delete working copies after the approved retention period.
