It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-5311 in the wild and no public exploit code.\n\nAffected product: Symantec Endpoint Protection. 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-2016-5311/ (Markdown: https://insights.sbomify.com/CVE-2016-5311/index.md)","id":"CVE-2016-5311","markdown":"https://insights.sbomify.com/CVE-2016-5311/index.md","name":"CVE-2016-5311","record":{"aliases":["GHSA-g7qp-85xf-w4q4"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Symantec Norton Security","requires_auth":"none","summary":"Local attackers can gain system privileges via DLL preloading in Symantec Norton and Endpoint Protection products.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"symantec","cpe":[{"product":"endpoint_protection","vendor":"symantec"},{"product":"endpoint_protection_cloud","vendor":"symantec"},{"product":"norton_360","vendor":"symantec"},{"product":"norton_antivirus","vendor":"symantec"},{"product":"norton_antivirus_with_backup","vendor":"symantec"},{"product":"norton_family","vendor":"symantec"},{"product":"norton_internet_security","vendor":"symantec"},{"product":"norton_security","vendor":"symantec"},{"product":"norton_security_with_backup","vendor":"symantec"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"A Privilege Escalation vulnerability exists in Symantec Norton Antivirus, Norton AntiVirus with Backup, Norton Security, Norton Security with Backup, Norton Internet Security, Norton 360, Endpoint Protection Small Business Edition Cloud, and Endpoint Protection Cloud Client due to a DLL-preloading without path restrictions, which could let a local malicious user obtain system privileges.","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 Endpoint Protection Small Business Edition Cloud, and Endpoint Protection Cloud Client","id":"CVE-2016-5311","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"symantec:endpoint_protection","products":["symantec:endpoint_protection","symantec:norton_antivirus"],"type":"privilege_escalation","year":"2016"},"n_packages":0,"n_references":5,"next":{"headline":"Path traversal in n/a","id":"CVE-2016-5312"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2016-5310"},"products":["Endpoint Protection Small Business Edition Cloud, and Endpoint Protection Cloud Client","Norton Antivirus, Norton AntiVirus with Backup, Norton Security, Norton Security with Backup, Norton Internet Security, Norton 360"],"published":"2020-01-09","related":[{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2012-0295","kev_date_added":null,"published":"2012-05-23"},{"cvss_score":8.8,"headline":"Privilege escalation in Symantec Endpoint Protection","id":"CVE-2018-5237","kev_date_added":null,"published":"2018-06-20"},{"cvss_score":7.8,"headline":"Privilege escalation in Symantec Endpoint Protection","id":"CVE-2020-5836","kev_date_added":null,"published":"2020-05-11"},{"cvss_score":7.8,"headline":"Path traversal in Symantec Endpoint Protection","id":"CVE-2020-5837","kev_date_added":null,"published":"2020-05-11"},{"cvss_score":7.8,"headline":"Privilege escalation in Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE)","id":"CVE-2020-5820","kev_date_added":null,"published":"2020-02-11"},{"cvss_score":7.8,"headline":"Code injection in Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE)","id":"CVE-2020-5821","kev_date_added":null,"published":"2020-02-11"},{"cvss_score":7.8,"headline":"Privilege escalation in Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE)","id":"CVE-2020-5822","kev_date_added":null,"published":"2020-02-11"}],"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":"2024-08-06","vendors":["Symantec"]},"summary":"Local attackers can gain system privileges via DLL preloading in Symantec Norton and Endpoint Protection products.","url":"https://insights.sbomify.com/CVE-2016-5311/"}
