Vulnerability from fkie_nvd - Published: 2026-10-12 05:17 - Updated: 2026-10-14 04:18

Severity

8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Summary

The Metasploit Framework post module post/apple_ios/gather/ios_image_gather is affected by a relative path traversal vulnerability (CWE-22). The module interpolates file names taken from a Meterpreter directory listing — data fully controlled by a hostile or tampered iOS device — directly into the local destination path passed to client.fs.file.download_file(), with no sanitization. The underlying stdapi sink (lib/rex/post/meterpreter/extensions/stdapi/fs/file.rb) writes to whatever path is supplied, so a listing entry such as ../../msfconsole.rc escapes the intended ~/.msf4/loot/<random> directory and overwrites ~/.msf4/msfconsole.rc, a resource file that every msfconsole invocation automatically executes at startup (lib/msf/ui/console/driver.rb:196). An attacker-controlled device that lures an operator into running this gather module achieves an arbitrary file write as the operator; because the written msfconsole.rc can load a second written file (a Ruby plugin whose top-level code runs on require), this converts into persistent code execution and an interactive shell as the operator (frequently root) on the pentester's workstation at the next console launch. The same traversal was previously fixed upstream in the recursive downloader (stdapi/fs/dir.rb scrubs separators); this module omitted the equivalent scrub. The fix applies the same separator scrub (or File.basename) to listing entries before building the local path.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
