Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the ReportTemplateController class. When parsing the path 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-12123.","provenance":"source","from":"CVE.org"},"summary":{"text":"The flaw is a path traversal weakness in the ReportTemplateController class of NETGEAR ProSAFE Network Management System, where the path parameter is used in file operations without proper validation. An attacker with network access and low-privilege credentials, or one who can bypass the existing authentication mechanism, can send a crafted request to delete arbitrary files on the system, which can cause a denial-of-service condition.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-29T07:18:31Z"},"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":0.7451,"percentile":0.99494,"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/000062723/Security-Advisory-for-Denial-of-Service-on-NMS300-PSV-2020-0537","tags":["x_refsource_MISC"]},{"url":"https://www.zerodayinitiative.com/advisories/ZDI-21-355/","tags":["x_refsource_MISC"]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2021-14037","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2021-14037","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-2021-27272","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":19.9,"detail":"percentile 0.9949"},{"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"}]}}
