An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

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/ 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.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
