{"id":"CVE-2018-15442","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-15442","generatedAt":"2026-10-29T02:04:08.858Z","title":"A vulnerability in the update service of Cisco Webex Meetings Desktop App for Windows could allow an authenticated, local attacker to execute arbitrary commands as a privileged user.","description":"A vulnerability in the update service of Cisco Webex Meetings Desktop App for Windows could allow an authenticated, local attacker to execute arbitrary commands as a privileged user. The vulnerability is due to insufficient validation of user-supplied parameters. An attacker could exploit this vulnerability by invoking the update service command with a crafted argument. An exploit could allow the attacker to run arbitrary commands with SYSTEM user privileges. While the CVSS Attack Vector metric denotes the requirement for an attacker to have local access, administrators should be aware that in Active Directory deployments, the vulnerability could be exploited remotely by leveraging the operating system remote management tools.","published":"2018-10-24T19:29:00.000Z","lastModified":"2026-06-17T01:42:30.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.0","score":7.8,"severity":"HIGH","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-78"],"affected":["cisco/webex meetings desktop","cisco/webex productivity tools"],"epss":{"score":0.1602,"percentile":0.96894,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":2,"verified":true,"firstPublished":"2018-10-25","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":45696,"kind":"exploit","title":"WebEx - Local Service Permissions Exploit (Metasploit)","url":"https://www.exploit-db.com/exploits/45696","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/windows/local/45696.rb","file":"exploits/windows/local/45696.rb","published":"2018-10-25","added":"2018-10-25","updated":"2018-10-25","author":"Metasploit","type":"local","platform":"windows","port":null,"verified":true,"codes":["CVE-2018-15442"],"tags":"Local","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://raw.githubusercontent.com/rapid7/metasploit-framework/2ab9a003d40e436e2f1099d0d164b76a0c2d4d33/modules/exploits/windows/local/webexec.rb"},{"edbId":45695,"kind":"exploit","title":"WebExec - (Authenticated) User Code Execution (Metasploit)","url":"https://www.exploit-db.com/exploits/45695","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/windows/remote/45695.rb","file":"exploits/windows/remote/45695.rb","published":"2018-10-25","added":"2018-10-25","updated":"2019-03-17","author":"Metasploit","type":"remote","platform":"windows","port":null,"verified":true,"codes":["CVE-2018-15442"],"tags":"Remote","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://raw.githubusercontent.com/rapid7/metasploit-framework/2ab9a003d40e436e2f1099d0d164b76a0c2d4d33/modules/exploits/windows/smb/webexec.rb"}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 16.0%, higher than 97% of all known CVEs.
