Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the MibController class. When parsing the realName parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-12122.","provenance":"source","from":"CVE.org"},"summary":{"text":"A path traversal flaw in the MibController class of NETGEAR ProSAFE Network Management System 1.6.0.26 lets the realName parameter be used in file operations without proper validation of the supplied path. A remote attacker with low-privilege authentication (which can be bypassed) and no user interaction can delete arbitrary files, producing a denial-of-service condition on the system.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-29T07:18:29Z"},"cvss":{"score":7.1,"severity":"HIGH","version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.73248,"percentile":0.99456,"date":"2026-10-29","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":0,"pulses":[],"provenance":"machine"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"references":[{"url":"https://kb.netgear.com/000062722/Security-Advisory-for-Denial-of-Service-on-NMS300-PSV-2020-0500","tags":["x_refsource_MISC"]},{"url":"https://www.zerodayinitiative.com/advisories/ZDI-21-359/","tags":["x_refsource_MISC"]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2021-14041","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2021-14041","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2021-03-29","kind":"published","label":"Published (CVE.org)","url":"https://www.cve.org/CVERecord?id=CVE-2021-27276","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":24.9,"factors":[{"name":"In a KEV catalog","points":0.0,"detail":"not listed"},{"name":"Recent KEV listing","points":0.0,"detail":"not listed"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":19.89,"detail":"percentile 0.9946"},{"name":"Named in threat reports","points":0.0,"detail":"0 reports"},{"name":"Public exploit code","points":0.0,"detail":"none found"},{"name":"Mentioned in OTX pulses","points":0.0,"detail":"0 pulses"},{"name":"CVSS severity","points":4.97,"detail":"base score 7.1"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
