An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15956 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-15956/ (Markdown: https://insights.sbomify.com/CVE-2020-15956/index.md)","id":"CVE-2020-15956","markdown":"https://insights.sbomify.com/CVE-2020-15956/index.md","name":"CVE-2020-15956","record":{"aliases":["GHSA-fc79-vjq3-f6j4"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NVR server software","requires_auth":"none","summary":"Remote unauthenticated attackers can cause denial of service in ACTi NVR3 Standard Server via a buffer overflow triggered by a malformed payload.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nvr","vendor":"acti"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"ActiveMediaServer.exe in ACTi NVR3 Standard Server 3.0.12.42 allows remote unauthenticated attackers to trigger a buffer overflow and application termination via a malformed payload.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2020-08-04","github_poc":1,"max_poc_stars":5,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-08-04T03:27:24Z","kind":"github_poc","ref":"https://github.com/megamagnus/cve-2020-15956","stars":5,"title":"ActiveMediaServer.exe in ACTi NVR3 Standard Server 3.0.12.42 allows remote unauthenticated attackers to trigger a buffer overflow and application termination via a malformed payload."},{"date":"2020-08-05","kind":"exploitdb","ref":"48731","stars":null,"title":"ACTi NVR3 Standard or Professional Server 3.0.12.42 - Denial of Service (PoC)"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2020-15956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Auth bypass in n/a","id":"CVE-2020-15957"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2020-15955"},"products":["n/a"],"published":"2020-08-04","related":[],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote unauthenticated attackers can cause denial of service in ACTi NVR3 Standard Server via a buffer overflow triggered by a malformed payload.","url":"https://insights.sbomify.com/CVE-2020-15956/"}
