An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-48957 exists.\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-2023-48957/ (Markdown: https://insights.sbomify.com/CVE-2023-48957/index.md)","id":"CVE-2023-48957","markdown":"https://insights.sbomify.com/CVE-2023-48957/index.md","name":"CVE-2023-48957","record":{"aliases":["GHSA-44pq-qvmw-gj4m"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"VPN client","requires_auth":"none","summary":"PureVPN Linux client fails to route DNS queries through the VPN tunnel, exposing user DNS requests to the ISP.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"purevpn","vendor":"purevpn"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"PureVPN Linux client 2.0.2-Productions fails to properly handle DNS queries, allowing them to bypass the VPN tunnel and be sent directly to the ISP or default DNS servers.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Information disclosure in n/a","id":"CVE-2023-48957","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2023-48958"},"packages":[],"prev":{"headline":"Deserialization in n/a","id":"CVE-2023-48952"},"products":["n/a"],"published":"2024-08-25","related":[{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2018-6822","kev_date_added":null,"published":"2018-02-07"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2018-10204","kev_date_added":null,"published":"2018-04-18"},{"cvss_score":7.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2018-18656","kev_date_added":null,"published":"2018-10-26"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2018-7484","kev_date_added":null,"published":"2018-02-26"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-14","vendors":["n/a"]},"summary":"PureVPN Linux client fails to route DNS queries through the VPN tunnel, exposing user DNS requests to the ISP.","url":"https://insights.sbomify.com/CVE-2023-48957/"}
