It has been rated as critical. Affected by this issue is some unknown functionality of the file /hedwig.cgi of the component HTTP POST Request Handler. The manipulation of the argument service with the input ../../../../htdocs/webinc/getcfg/DHCPS6.BRIDGE-1.xml leads to path traversal. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-251666 is the identifier assigned to this vulnerability. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced.","provenance":"source","from":"NVD"},"summary":{"text":"A path traversal flaw exists in the HTTP POST request handler of the /hedwig.cgi file in the D-Link DIR-859 Router, 1.06B01, where the service argument is not restricted to a safe directory. A remote attacker can exploit it without authentication or user interaction by submitting a crafted traversal value in that argument, and the vendor has confirmed the product is end-of-life and unsupported.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-30T13:35:59Z"},"cvss":{"score":9.8,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.82714,"percentile":0.99666,"date":"2026-10-29","provenance":"source"},"kev":{"dateAdded":"2025-06-25","dueDate":"2025-07-16","ransomware":false,"requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","notes":"https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10371 ; https://nvd.nist.gov/vuln/detail/CVE-2024-0769","provenance":"source"},"vulncheckKev":{"dateAdded":"2024-06-25","exploitedFirstSeen":"2024-06-25","ransomware":false,"evidence":[{"url":"https://www.labs.greynoise.io/grimoire/2024-06-25-dlink-again/","date":"2024-06-25"},{"url":"https://cyble.com/blog/cyble-honeypot-sensors-detect-d-link-cisco-qnap-and-linux-attacks/","date":"2024-10-07"},{"url":"https://app.crowdsec.net/cti/cve-explorer/CVE-2024-0769","date":"2025-06-07"},{"url":"https://www.cisa.gov/sites/default/files/feeds/known_exploited_vulnerabilities.json","date":"2025-06-25"},{"url":"https://assets.recordedfuture.com/insikt-report-pdfs/2025/cta-2025-0828.pdf","date":"2025-08-28"},{"url":"https://cyble.com/resources/research-reports/global-cybersecurity-report/","date":"2025-12-11"},{"url":"https://www.loginsoft.com/reports/annually/vulnerability-intelligence-report-2025","date":"2026-01-20"}],"evidenceTotal":7,"provenance":"source"},"exploited":true,"otx":{"pulseCount":50,"pulses":[{"name":"Actively_Exploited_Kev | Oct 30, 2026","url":"https://otx.alienvault.com/pulse/6ae35d889ea92b4ce19c2680","created":"2026-10-29"},{"name":"Actively_Exploited_Kev | Oct 29, 2026","url":"https://otx.alienvault.com/pulse/6ae20c1db17e7057ae7d9ad1","created":"2026-10-28"},{"name":"Actively_Exploited_Kev | Oct 28, 2026","url":"https://otx.alienvault.com/pulse/6ae0ba7e0e2a97ff7b218819","created":"2026-10-27"},{"name":"Actively_Exploited_Kev | Oct 27, 2026","url":"https://otx.alienvault.com/pulse/6adf68b85c3e852f3c111d18","created":"2026-10-26"},{"name":"Actively_Exploited_Kev | Oct 24, 2026","url":"https://otx.alienvault.com/pulse/6adb740e397c3ad4799aa4cd","created":"2026-10-23"},{"name":"Actively_Exploited_Kev | Oct 23, 2026","url":"https://otx.alienvault.com/pulse/6ada236fcfba2dfa730ea482","created":"2026-10-22"},{"name":"Actively_Exploited_Kev | Oct 22, 2026","url":"https://otx.alienvault.com/pulse/6ad8d33a077cbb5cab524d80","created":"2026-10-21"},{"name":"Actively_Exploited_Kev | Oct 21, 2026","url":"https://otx.alienvault.com/pulse/6ad78130c4d1ac2be83a8b6d","created":"2026-10-20"},{"name":"Actively_Exploited_Kev | Oct 20, 2026","url":"https://otx.alienvault.com/pulse/6ad62f63c24a405a3423cc13","created":"2026-10-19"},{"name":"Actively_Exploited_Kev | Oct 19, 2026","url":"https://otx.alienvault.com/pulse/6ad4dda174e5797d0bd238b7","created":"2026-10-18"}],"provenance":"machine"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"references":[{"url":"https://github.com/c2dc/cve-reported/blob/main/CVE-2024-0769/CVE-2024-0769.md","tags":["Exploit","Third Party Advisory"]},{"url":"https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10371","tags":["Vendor Advisory"]},{"url":"https://vuldb.com/?ctiid.251666","tags":["Permissions Required","VDB Entry"]},{"url":"https://vuldb.com/?id.251666","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://github.com/c2dc/cve-reported/blob/main/CVE-2024-0769/CVE-2024-0769.md","tags":["Exploit","Third Party Advisory"]},{"url":"https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10371","tags":["Vendor Advisory"]},{"url":"https://vuldb.com/?ctiid.251666","tags":["Permissions Required","VDB Entry"]},{"url":"https://vuldb.com/?id.251666","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2024-0769","tags":["US Government Resource"]},{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2024-0769","tags":["US Government Resource"]}],"techniques":[{"id":"T1190","name":"Exploit Public-Facing Application","tactics":["initial-access"],"provenance":"source","basis":"ctid-kev","bases":["ctid-kev"],"basisDetail":"CTID Mappings Explorer KEV 07/28/2025 (ATT&CK 16.1); capability: Directory Traversal (Relative and Absolute)","mappingType":"exploitation_technique","evidence":[],"comment":"This path traversal vulnerability in D-Link DIR-859 WiFi routers can lead to information disclosure, such as configuration files.
