An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-33389 in the wild and no public exploit code.\n\nAffected product: Nozomi Networks Arc. 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-2026-33389/ (Markdown: https://insights.sbomify.com/CVE-2026-33389/index.md)","id":"CVE-2026-33389","markdown":"https://insights.sbomify.com/CVE-2026-33389/index.md","name":"CVE-2026-33389","record":{"aliases":["GHSA-8g88-35qx-36v7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Nozomi Networks Arc","requires_auth":"none","summary":"Attackers can intercept credentials via man-in-the-middle attacks due to disabled certificate validation in Smart Polling, allowing device access and tampering.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-671","name":"Lack of Administrator Control over Security"}],"description":"An improper certificate/host key validation vulnerability was discovered in the Smart Polling functionality, which established encrypted connections to target devices without validating the remote host's identity, and no option was provided to enable it. A man-in-the-middle attacker positioned between a sensor and a polled device can, during a polling session, impersonate the device and intercept the communication, including the credentials used to access it. The captured credentials can then be replayed to authenticate against the device itself or against other devices sharing the same credentials, allowing the attacker to access and tamper with the device's data and to disrupt its operations.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Security feature bypass in Arc","id":"CVE-2026-33389","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Incorrect privilege assignment for Arc sensors in Guardian/CMC before 26.2.0","id":"CVE-2026-33390"},"packages":[],"prev":{"headline":"Incorrect authorization in Credentials Manager in Guardian/CMC before 26.3.0","id":"CVE-2026-33388"},"products":["Arc","CMC","Guardian"],"published":"2026-09-08","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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Nozomi Networks"]},"summary":"Attackers can intercept credentials via man-in-the-middle attacks due to disabled certificate validation in Smart Polling, allowing device access and tampering.","url":"https://insights.sbomify.com/CVE-2026-33389/"}
