It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-6421 in the wild and no public exploit code.\n\nAffected product: Mobatek MobaXterm Home Edition. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-6421/ (Markdown: https://insights.sbomify.com/CVE-2026-6421/index.md)","id":"CVE-2026-6421","markdown":"https://insights.sbomify.com/CVE-2026-6421/index.md","name":"CVE-2026-6421","record":{"aliases":["GHSA-hf75-j846-hmxr"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SSH client","requires_auth":"low_privilege","summary":"Local attackers can exploit an uncontrolled search path in msimg32.dll to execute arbitrary code, requiring high complexity and local access.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"},{"id":"CWE-426","name":"Untrusted Search Path"}],"description":"A vulnerability has been found in Mobatek MobaXterm Home Edition up to 26.1. This affects an unknown part in the library msimg32.dll. The manipulation leads to uncontrolled search path. An attack has to be approached locally. The attack is considered to have high complexity. It is indicated that the exploitability is difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 26.2 is able to mitigate this issue. It is suggested to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-07-06","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-07-06T10:18:00Z","kind":"github_poc","ref":"https://github.com/1neptune/chimera","stars":0,"title":"Rust-based DLL hijacking loader for MobaXterm (CVE-2026-6421) with persistence"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Mobatek MobaXterm Home Edition msimg32.dll uncontrolled search path","id":"CVE-2026-6421","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"Local privilege escalation via unauthenticated ALPC in ESET Inspect Connector","id":"CVE-2026-6423"},"packages":[],"prev":{"headline":"Keylime: keylime: security bypass due to hardcoded tpm quote nonce","id":"CVE-2026-6420"},"products":["MobaXterm Home Edition"],"published":"2026-04-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-17","vendors":["Mobatek"]},"summary":"Local attackers can exploit an uncontrolled search path in msimg32.dll to execute arbitrary code, requiring high complexity and local access.","url":"https://insights.sbomify.com/CVE-2026-6421/"}
