The files are created and written with a SYSTEM account except one file (logplaceholder) which inherits permission giving all users full access control list. Netskope client restricts access to this file by allowing only read permissions as a standard user. Whenever the Netskope client service restarts, it deletes the logplaceholder and recreates, creating a race condition, which can be exploited by a malicious local user to create the file and set ACL permissions on the file. Once the file is created by a malicious user with proper ACL permissions, all files within C:\\Users\\Public\\netSkope\\ becomes modifiable by the unprivileged user. By using Windows pseudo-symlink, these files can be pointed to other places in the system and thus malicious users will be able to elevate privileges.\n"}],"id":"CVE-2022-4149","lastModified":"2026-06-17T05:20:05.780","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"HIGH","attackVector":"LOCAL","availabilityImpact":"HIGH","baseScore":7.0,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"exploitabilityScore":1.0,"impactScore":5.9,"source":"psirt@netskope.com","type":"Secondary"},{"cvssData":{"attackComplexity":"HIGH","attackVector":"LOCAL","availabilityImpact":"HIGH","baseScore":7.0,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"exploitabilityScore":1.0,"impactScore":5.9,"source":"nvd@nist.gov","type":"Primary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2022-4149","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","timestamp":"2024-12-12T17:04:43.872061Z","version":"2.0.3"}}]},"published":"2023-06-15T07:15:08.710","references":[{"source":"psirt@netskope.com","tags":["Vendor Advisory"],"url":"https://www.netskope.com/company/security-compliance-and-assurance/security-advisories-and-disclosures/netskope-security-advisory-nskpsa-2023-002"},{"source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"],"url":"https://www.netskope.com/company/security-compliance-and-assurance/security-advisories-and-disclosures/netskope-security-advisory-nskpsa-2023-002"}],"sourceIdentifier":"psirt@netskope.com","vulnStatus":"Modified","weaknesses":[{"description":[{"lang":"en","value":"CWE-367"}],"source":"psirt@netskope.com","type":"Secondary"},{"description":[{"lang":"en","value":"CWE-367"}],"source":"nvd@nist.gov","type":"Primary"}]}
