Description
A flaw was found in assisted-migration-agent. An unauthenticated attacker, located on the same local area network (LAN), can exploit a path traversal vulnerability. By crafting a specially designed gzipped tarball, the attacker can bypass security checks and write arbitrary files to the system. This could ultimately lead to the execution of unauthorized code on the appliance.

Impact

The vulnerability in assisted‑migration‑agent enables an unauthenticated attacker on the same local area network to craft a specially designed gzipped tarball that bypasses security checks. By exploiting a path‑traversal flaw, the attacker can write arbitrary files to the system, effectively allowing execution of unauthorized code. This flaw corresponds to CWE‑59 and carries a CVSS score of 9.6, indicating critical severity.

Affected Systems

Products affected are instances of the assisted‑migration‑agent software distributed by Red Hat. No specific version information is provided in the advisory, so the vulnerability may exist in all releases prior to the fix.

Risk and Exploitability

The CVSS score of 9.6 signals a very high risk of successful exploitation. EPSS data is not available, but the vulnerability is not listed in the CISA KEV catalog. The attack vector is inferred to be local network traffic directed at the agent, as the attacker must be able to deliver a crafted tarball over the LAN. If exploited, the attacker could overwrite critical configuration or binary files and achieve remote code execution on the appliance.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the assisted‑migration‑agent package to the vendor‑supplied fix that addresses the path‑traversal issue.
  • Restrict access to the migration agent by configuring firewall rules or network segmentation so that only trusted hosts can reach it over the LAN.
  • Disable the ability to upload tarball files for migration until the vulnerability is patched.
  • Review any automated migration workflows to ensure they do not use untrusted tarball inputs before remediation is complete.
