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-2018-17785 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.github.blynkkk:blynk-server (Maven): affected all versions; fixed in 0.39.7\n- com.github.blynkkk:blynk-server (Maven): affected all versions; fixed in 0.39.7\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-2018-17785/ (Markdown: https://insights.sbomify.com/CVE-2018-17785/index.md)","id":"CVE-2018-17785","markdown":"https://insights.sbomify.com/CVE-2018-17785/index.md","name":"CVE-2018-17785","record":{"aliases":["GHSA-4r64-wf76-c53p"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Blynk IoT server","requires_auth":"none","summary":"An attacker can read arbitrary files on the server by exploiting a directory traversal vulnerability in the Blynk server's static file handling.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"blynk-server","vendor":"blynk"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"In blynk-server in Blynk before 0.39.7, Directory Traversal exists via a ../ in a URI that has /static or /static/js at the beginning, as demonstrated by reading the /etc/passwd file.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"In blynk-server a Directory Traversal exists","id":"CVE-2018-17785","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2018"},"n_packages":2,"n_references":2,"next":{"headline":"Missing authorization in n/a","id":"CVE-2018-17786"},"packages":[{"ecosystem":"Maven","fixed":["0.39.7"],"introduced":["0"],"last_affected":[],"package":"com.github.blynkkk:blynk-server","purl":null,"source":"GHSA-4r64-wf76-c53p"},{"ecosystem":"Maven","fixed":["0.39.7"],"introduced":["0"],"last_affected":[],"package":"com.github.blynkkk:blynk-server","purl":"pkg:maven/com.github.blynkkk/blynk-server","source":"GHSA-4r64-wf76-c53p"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-17784"},"products":["n/a"],"published":"2018-09-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-09-16","vendors":["n/a"]},"summary":"An attacker can read arbitrary files on the server by exploiting a directory traversal vulnerability in the Blynk server's static file handling.","url":"https://insights.sbomify.com/CVE-2018-17785/"}
