    Rapid7 Metasploit Framework: Path Traversal (CVE-2026-87690)

    Published Last modified Sources: CVE.org

    What is affected, what to do

    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.

    An exploit is publicly available. Update Rapid7 Metasploit Framework to version 6.5.5.

    The priority score is a consolidated metric that condenses several individual signals into a single, action-guiding ranking: technical severity (CVSS), exploitation likelihood (EPSS), known-exploited status (KEV) and the context of the affected asset. The aim is to answer the only truly important question in vulnerability management: what first?

    Exploit maturity

    An exploit is code or a technique that specifically uses a concrete vulnerability to force unintended behaviour — such as executing code or escalating privileges. It is the tool that turns a theoretical flaw into a practical attack.

    XIEM Effective CVSS

    XIEM® is the tiered managed-security operating model from NEOSEC and a registered trademark of NEOSEC GmbH. It extends classic SIEM — the central collection, normalisation and correlation of security-relevant events — with endpoint forensics, network visibility and deception technology, and consolidates them into three building tiers: Sentry, Orchestrate and Command.

    8.8 Methodology
    CVSS v3

    CVSS is the globally established, open standard for assessing the technical severity of a vulnerability on a scale from 0 to 10. It describes how easily a flaw can be exploited and what damage it can cause — but not how likely its actual exploitation is. CVSS and the complementary EPSS deliberately answer different questions.

    8.8
    EPSS score

    The EPSS score is the absolute model output for an individual vulnerability: the estimated probability of real-world exploitation within the next 30 days, expressed as a value between 0 and 1 (i.e. 0 % to 100 %). A score of 0.42 means „the model estimates a 42 % chance of real-world exploitation within 30 days“.

    Read in glossary
    0.4 %
    Low — model estimates < 1% exploitation likelihood.
    EPSS percentile

    The EPSS percentile is the relative position of a vulnerability within all EPSS-scored CVEs, expressed as a value between 0 and 1. A percentile of 0.90 means „this CVE has a higher EPSS score than 90 % of all other scored CVEs“. Unlike the EPSS score, it is not a probability — but a positioning within a ranking.

    35.3
    Elevated — this CVE ranks above at least 10% of all CVEs scored today.
    KEV status

    The KEV catalogue is a list maintained by the US authority CISA of vulnerabilities for which active exploitation in the wild has been confirmed. It answers not the question „how severe?“ but „is it already being attacked?“ — thereby sharply prioritising patching.

    Classification under NIS2 and CRA

    Rule-based classification from exploitation status and severity. It does not replace a case-by-case assessment.

    NIS2

    NIS2 is EU Directive (EU) 2022/2555 to raise the level of cybersecurity across the Union. It substantially broadens obligations compared with the first NIS directive: more sectors, mandatory risk management, staged reporting duties and personal accountability of senior management.

    CRA

    The CRA is EU Regulation (EU) 2024/2847 setting horizontal cybersecurity requirements for „products with digital elements“ — from industrial controllers and software to connected consumer devices. For the first time manufacturers must ensure security across the entire product lifecycle, handle vulnerabilities and provide security updates.

    Read in glossary
    From 11.12.2027, Annex I Part II CRA requires manufacturers of affected products with digital elements to handle vulnerabilities without delay and provide security updates.

    Description

    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.
