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-2021-33526 in the wild and no public exploit code.\n\nAffected product: mbDIALUP. 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-2021-33526/ (Markdown: https://insights.sbomify.com/CVE-2021-33526/index.md)","id":"CVE-2021-33526","markdown":"https://insights.sbomify.com/CVE-2021-33526/index.md","name":"CVE-2021-33526","record":{"aliases":["GHSA-2992-6547-hhfp"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"mbDIALUP client","requires_auth":"low_privilege","summary":"A local attacker can escalate privileges to SYSTEM by sending a malicious command to the mbDIALUP service, leading to arbitrary code execution.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"mbdialup","vendor":"mbconnectline"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"In MB connect line mbDIALUP versions \u003c= 3.9R0.0 a low privileged local attacker can send a command to the service running with NT AUTHORITY\\SYSTEM instructing it to execute a malicous OpenVPN configuration resulting in arbitrary code execution with the privileges of the service.","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":"Privilege escalation in mbDIALUP \u003c= 3.9R0.0","id":"CVE-2021-33526","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"OS Command Injection in mbDIALUP \u003c= 3.9R0.0","id":"CVE-2021-33527"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2021-33525"},"products":["mbDIALUP"],"published":"2021-08-02","related":[{"cvss_score":9.8,"headline":"OS Command Injection in mbDIALUP \u003c= 3.9R0.0","id":"CVE-2021-33527","kev_date_added":null,"published":"2021-08-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["MB connect line"]},"summary":"A local attacker can escalate privileges to SYSTEM by sending a malicious command to the mbDIALUP service, leading to arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2021-33526/"}
