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-2020-8249 in the wild and no public exploit code.\n\nAffected product: Pulse Secure Desktop Client. 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-2020-8249/ (Markdown: https://insights.sbomify.com/CVE-2020-8249/index.md)","id":"CVE-2020-8249","markdown":"https://insights.sbomify.com/CVE-2020-8249/index.md","name":"CVE-2020-8249","record":{"aliases":["GHSA-73qf-8rvq-9ffc"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Pulse Secure Desktop Client","requires_auth":"low_privilege","summary":"Local attackers can exploit a buffer overflow in the Pulse Secure Desktop Client for Linux to execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"pulse_secure_desktop_client","vendor":"pulsesecure"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A vulnerability in the Pulse Secure Desktop Client (Linux) \u003c 9.1R9 could allow local attackers to perform buffer overflow.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-11-26","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-11-26T13:28:07Z","kind":"github_poc","ref":"https://github.com/mbadanoiu/CVE-2020-8249","stars":0,"title":"CVE-2020-8249: Buffer Overflow in Pulse Secure VPN Linux Client"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Memory corruption in Pulse Secure Desktop Client","id":"CVE-2020-8249","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Pulse Secure Desktop Client","id":"CVE-2020-8250"},"packages":[],"prev":{"headline":"Privilege escalation in Pulse Secure Desktop Client","id":"CVE-2020-8248"},"products":["Pulse Secure Desktop Client"],"published":"2020-10-28","related":[{"cvss_score":9.8,"headline":"Privilege escalation in Pulse Secure Desktop Cient","id":"CVE-2020-8239","kev_date_added":null,"published":"2020-10-28"},{"cvss_score":8.8,"headline":"Path traversal in Pulse Secure Desktop Client","id":"CVE-2020-8254","kev_date_added":null,"published":"2020-10-28"},{"cvss_score":7.8,"headline":"Privilege escalation in Pulse Secure Desktop Client","id":"CVE-2020-8240","kev_date_added":null,"published":"2020-10-28"},{"cvss_score":7.8,"headline":"Privilege escalation in Pulse Secure Desktop Client","id":"CVE-2020-8248","kev_date_added":null,"published":"2020-10-28"},{"cvss_score":7.8,"headline":"Privilege escalation in Pulse Secure Desktop Client","id":"CVE-2020-8250","kev_date_added":null,"published":"2020-10-28"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2018-15865","kev_date_added":null,"published":"2018-09-06"}],"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":"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":"Local attackers can exploit a buffer overflow in the Pulse Secure Desktop Client for Linux to execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2020-8249/"}
