{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/62863?format=json","vulnerability_id":"VCID-q2t7-31ux-cyc6","summary":"On Windows systems, the logger run by the Windows updater deletes the file \"update.log\" before it runs in order to write a new log of that name. The path to this file is supplied at the command line to the updater and could be used in concert with another local exploit to delete a different file named \"update.log\" instead of the one intended. *Note: This attack only affects Windows operating systems. Other operating systems are not affected.*","aliases":[{"alias":"CVE-2017-7796"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/582227?format=json","purl":"pkg:deb/debian/firefox@0?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@0%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/582059?format=json","purl":"pkg:deb/debian/firefox@149.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@149.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1059611?format=json","purl":"pkg:deb/debian/firefox@149.0.2-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@149.0.2-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1076056?format=json","purl":"pkg:deb/debian/firefox@150.0-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1088670?format=json","purl":"pkg:deb/debian/firefox@150.0.1-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/firefox@150.0.1-1%3Fdistro=sid"}],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2017-7796","reference_id":"","reference_type":"","scores":[{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17561","published_at":"2026-05-05T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17881","published_at":"2026-04-01T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17764","published_at":"2026-04-24T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17741","published_at":"2026-04-26T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17705","published_at":"2026-04-29T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.18041","published_at":"2026-04-02T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.18096","published_at":"2026-04-04T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17798","published_at":"2026-04-07T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17885","published_at":"2026-04-08T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17946","published_at":"2026-04-09T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17963","published_at":"2026-04-11T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17918","published_at":"2026-04-12T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17868","published_at":"2026-04-13T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17811","published_at":"2026-04-16T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17821","published_at":"2026-04-18T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.17858","published_at":"2026-04-21T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2017-7796"},{"reference_url":"https://bugzilla.mozilla.org/show_bug.cgi?id=1234401","reference_id":"","reference_type":"","scores":[],"url":"https://bugzilla.mozilla.org/show_bug.cgi?id=1234401"},{"reference_url":"https://www.mozilla.org/security/advisories/mfsa2017-18/","reference_id":"","reference_type":"","scores":[],"url":"https://www.mozilla.org/security/advisories/mfsa2017-18/"},{"reference_url":"http://www.securitytracker.com/id/1039124","reference_id":"","reference_type":"","scores":[],"url":"http://www.securitytracker.com/id/1039124"},{"reference_url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:a:mozilla:firefox:*:*:*:*:*:*:*:*","reference_id":"cpe:2.3:a:mozilla:firefox:*:*:*:*:*:*:*:*","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:a:mozilla:firefox:*:*:*:*:*:*:*:*"},{"reference_url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:o:microsoft:windows:-:*:*:*:*:*:*:*","reference_id":"cpe:2.3:o:microsoft:windows:-:*:*:*:*:*:*:*","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:o:microsoft:windows:-:*:*:*:*:*:*:*"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2017-7796","reference_id":"CVE-2017-7796","reference_type":"","scores":[{"value":"3.3","scoring_system":"cvssv2","scoring_elements":"AV:L/AC:M/Au:N/C:N/I:P/A:P"},{"value":"4.7
