The vulnerability is due to the incorrect handling of directory paths. An attacker could exploit this vulnerability by creating a malicious file and copying the file to a system directory. An exploit could allow the attacker to copy malicious files to arbitrary locations with system level privileges. This could include DLL pre-loading, DLL hijacking, and other related attacks. To exploit this vulnerability, the attacker needs valid credentials on the Windows system.","severity":{"version":"3.0","score":6.5,"vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.28515,"percentile":0.98144,"model":"v2026.06.15"},"facts":{"in_kev":true,"known_exploited":true,"public_exploit":true,"fix_available":false},"cwes":["CWE-427"],"published":"2020-02-19T19:15:53Z","modified":"2026-08-12T05:17:29Z","kev":{"date_added":"2022-10-24","due_date":"2022-11-14","required_action":"Apply updates per vendor instructions.","known_ransomware_use":"Known"},"exploitation":[{"source":"euvd","since":"2022-10-24"},{"source":"kev","since":"2022-10-24"}],"exploits":[{"source":"pocgithub","id":"shubham0d/CVE-2020-3153","title":"shubham0d/CVE-2020-3153","date":"2020-05-04","url":"https://github.com/shubham0d/CVE-2020-3153"},{"source":"pocgithub","id":"raspberry-pie/CVE-2020-3153","title":"raspberry-pie/CVE-2020-3153","date":"2020-05-15","url":"https://github.com/raspberry-pie/CVE-2020-3153"},{"source":"pocgithub","id":"goichot/CVE-2020-3153","title":"goichot/CVE-2020-3153","date":"2020-05-19","url":"https://github.com/goichot/CVE-2020-3153"},{"source":"metasploit","id":"exploit/windows/local/anyconnect_lpe","title":"Cisco AnyConnect Privilege Escalations (CVE-2020-3153 and CVE-2020-3433)","type":"exploit","platform":"Windows","date":"2020-08-05","verified":true,"url":"https://www.rapid7.com/db/modules/exploit/windows/local/anyconnect_lpe"}],"products":[{"vendor":"cisco","product":"anyconnect secure"},{"vendor":"cisco","product":"anyconnect_secure_mobility_client"},{"vendor":"cisco","product":"cisco anyconnect secure mobility client"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ac-win-path-traverse-qO4HWBsj","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"http://seclists.org/fulldisclosure/2020/Apr/43","tags":["mailing-list","x_refsource_FULLDISC","x_transferred","Exploit","Mailing List","Third Party Advisory"]},{"url":"http://packetstormsecurity.com/files/157340/Cisco-AnyConnect-Secure-Mobility-Client-4.8.01090-Privilege-Escalation.html","tags":["x_refsource_MISC","x_transferred","Exploit","Third Party Advisory","VDB Entry"]},{"url":"http://packetstormsecurity.com/files/158219/Cisco-AnyConnect-Path-Traversal-Privilege-Escalation.html","tags":["x_refsource_MISC","x_transferred","Exploit","Third Party Advisory","VDB Entry"]},{"url":"http://packetstormsecurity.com/files/159420/Cisco-AnyConnect-Privilege-Escalation.html","tags":["x_refsource_MISC","x_transferred","Exploit","Third Party Advisory","VDB Entry"]},{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2020-3153","tags":["government-resource","US Government Resource"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3153"},{"url":"https://github.com/advisories/GHSA-xpxv-rfwh-rcfc"}],"sources":{"cve":[{"id":"CVE-2020-3153","title":"Cisco AnyConnect Secure Mobility Client for Windows Uncontrolled Search Path Vulnerability","description":"A vulnerability in the installer component of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated local attacker to copy user-supplied files to system level directories with system level privileges.
