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-2015-7256 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-2015-7256/ (Markdown: https://insights.sbomify.com/CVE-2015-7256/index.md)","id":"CVE-2015-7256","markdown":"https://insights.sbomify.com/CVE-2015-7256/index.md","name":"CVE-2015-7256","record":{"aliases":["GHSA-36v6-x937-539h"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ZyXEL network devices","requires_auth":"none","summary":"ZyXEL network devices use non-unique X.509 certificates and SSH host keys, enabling man-in-the-middle attacks and impersonation.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"c1000z_firmware","vendor":"zyxel"},{"product":"fr1000z_firmware","vendor":"zyxel"},{"product":"gs1900-24_firmware","vendor":"zyxel"},{"product":"gs1900-8_firmware","vendor":"zyxel"},{"product":"nwa1100-n_firmware","vendor":"zyxel"},{"product":"nwa1100-nh_firmware","vendor":"zyxel"},{"product":"nwa1121-ni_firmware","vendor":"zyxel"},{"product":"nwa1123-ac_firmware","vendor":"zyxel"},{"product":"nwa1123-ni_firmware","vendor":"zyxel"},{"product":"p-660hn-51_firmware","vendor":"zyxel"},{"product":"p-663hn-51_firmware","vendor":"zyxel"},{"product":"p8702n_firmware","vendor":"zyxel"},{"product":"pmg5318-b20a_firmware","vendor":"zyxel"},{"product":"q1000_firmware","vendor":"zyxel"},{"product":"sbg3300-n000_firmware","vendor":"zyxel"},{"product":"sbg3300-nb00_firmware","vendor":"zyxel"},{"product":"sbg3500-n000_firmware","vendor":"zyxel"},{"product":"vmg1312-b10a_firmware","vendor":"zyxel"},{"product":"vmg1312-b30a_firmware","vendor":"zyxel"},{"product":"vmg1312-b30b_firmware","vendor":"zyxel"},{"product":"vmg4380-b10a_firmware","vendor":"zyxel"},{"product":"vmg8324-b10a_firmware","vendor":"zyxel"},{"product":"vmg8924-b10a_firmware","vendor":"zyxel"},{"product":"vmg8924-b30a_firmware","vendor":"zyxel"},{"product":"vsg1435-b101_firmware","vendor":"zyxel"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-310","name":null}],"description":"ZyXEL NWA1100-N, NWA1100-NH, NWA1121-NI, NWA1123-AC, and NWA1123-NI access points; P-660HN-51, P-663HN-51, VMG1312-B10A, VMG1312-B30A, VMG1312-B30B, VMG4380-B10A, VMG8324-B10A, VMG8924-B10A, VMG8924-B30A, and VSG1435-B101 DSL CPEs; PMG5318-B20A GPONs; SBG3300-N000, SBG3300-NB00, and SBG3500-N000 small business gateways; GS1900-8 and GS1900-24 switches; and C1000Z, Q1000, FR1000Z, and P8702N project models use non-unique X.509 certificates and SSH host keys.","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":"Weak cryptography in n/a","id":"CVE-2015-7256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2015"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2015-7257"},"packages":[],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2015-7255"},"products":["n/a"],"published":"2017-09-27","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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"ZyXEL network devices use non-unique X.509 certificates and SSH host keys, enabling man-in-the-middle attacks and impersonation.","url":"https://insights.sbomify.com/CVE-2015-7256/"}
