This is implemented using a shell script, and the code which handled network names was not careful to prevent expansion by the shell.  As a result, a suitably crafted network name can be used to execute commands via a subshell.\n\nThe problem can be exploited to execute code as root on the system running bsdinstall or bsdconfig.  The attacker would need to create an access point with a specially crafted name and be within range of a Wi-Fi scan.  Note that bsdinstall and bsdconfig are vulnerable as soon as the user prompts them to scan for nearby networks; they do not need to actually select the malicious network."}],"problemTypes":[{"descriptions":[{"cweId":"CWE-78","description":"CWE-78: Improper Neutralization of Special Elements used in an OS Command","lang":"en","type":"CWE"}]}],"providerMetadata":{"orgId":"63664ac6-956c-4cba-a5d0-f46076e16109","shortName":"freebsd","dateUpdated":"2026-05-21T09:27:20.431Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.5,"attackVector":"ADJACENT_NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-05-21T00:00:00+00:00","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3","id":"CVE-2026-45255"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-22T03:55:39.175Z"}}]}}
