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-2018-17153 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-2018-17153/ (Markdown: https://insights.sbomify.com/CVE-2018-17153/index.md)","id":"CVE-2018-17153","markdown":"https://insights.sbomify.com/CVE-2018-17153/index.md","name":"CVE-2018-17153","record":{"aliases":["GHSA-22xm-47fv-r79q"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Western Digital My Cloud","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication to gain admin privileges and full control of Western Digital My Cloud devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"my_cloud_dl2100","vendor":"western_digital"},{"product":"my_cloud_dl4100_firmware","vendor":"western_digital"},{"product":"my_cloud_ex2100_firmware","vendor":"western_digital"},{"product":"my_cloud_ex2_firmware","vendor":"western_digital"},{"product":"my_cloud_ex2_ultra_firmware","vendor":"western_digital"},{"product":"my_cloud_ex4100","vendor":"western_digital"},{"product":"my_cloud_ex4_firmware","vendor":"western_digital"},{"product":"my_cloud_mirror_firmware","vendor":"western_digital"},{"product":"my_cloud_mirror_gen_2_firmware","vendor":"western_digital"},{"product":"my_cloud_pr2100_firmware","vendor":"western_digital"},{"product":"my_cloud_pr4100","vendor":"western_digital"},{"product":"my_cloud_wdbctl0020hwt_firmware","vendor":"western_digital"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"It was discovered that the Western Digital My Cloud device before 2.30.196 is affected by an authentication bypass vulnerability. An unauthenticated attacker can exploit this vulnerability to authenticate as an admin user without needing to provide a password, thereby gaining full control of the device. (Whenever an admin logs into My Cloud, a server-side session is created that is bound to the user's IP address. After the session is created, it is possible to call authenticated CGI modules by sending the cookie username=admin in the HTTP request. The invoked CGI will check if a valid session is present and bound to the user's IP address.) It was found that it is possible for an unauthenticated attacker to create a valid session without a login. The network_mgr.cgi CGI module contains a command called \"cgi_get_ipv6\" that starts an admin session -- tied to the IP address of the user making the request -- if the additional parameter \"flag\" with the value \"1\" is provided. Subsequent invocation of commands that would normally require admin privileges now succeed if an attacker sets the username=admin cookie.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2016-12-14","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":1,"refs":[{"date":"2016-12-14","kind":"metasploit","ref":"exploit/linux/http/wd_mycloud_unauthenticated_cmd_injection","stars":null,"title":"Western Digital MyCloud unauthenticated command injection"},{"date":null,"kind":"nuclei","ref":"http/cves/2018/CVE-2018-17153.yaml","stars":null,"title":"Western Digital MyCloud NAS - Authentication Bypass"}],"tier":"weaponised"},"has_fix":null,"headline":"Auth bypass in n/a","id":"CVE-2018-17153","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2018"},"n_packages":0,"n_references":4,"next":{"headline":"Null dereference in FreeBSD","id":"CVE-2018-17154"},"packages":[],"prev":{"headline":"XML external entity in n/a","id":"CVE-2018-17152"},"products":["n/a"],"published":"2018-09-18","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2019-9951","kev_date_added":null,"published":"2019-04-24"}],"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":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Unauthenticated attackers can bypass authentication to gain admin privileges and full control of Western Digital My Cloud devices.","url":"https://insights.sbomify.com/CVE-2018-17153/"}
