The vulnerability is due to the lack of a proper locking mechanism on critical variables that need to stay static until used. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a set of RPM-related CLI commands. A successful exploit could allow the attacker to perform arbitrary command injection. The attacker would need administrator credentials for the targeted device.","severity":{"version":"3.0","score":6.4,"vector":"CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.00357,"percentile":0.29678,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-667","CWE-78"],"published":"2019-05-15T16:50:29Z","modified":"2026-06-17T02:29:09Z","products":[{"vendor":"cisco","product":"cisco nx-os software"},{"vendor":"cisco","product":"nx-os"},{"vendor":"cisco","product":"nx_os"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-rpm-injec","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/108361","tags":["vdb-entry","x_refsource_BID","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1732"},{"url":"https://github.com/advisories/GHSA-p72g-8563-4jg8"}],"sources":{"cve":[{"id":"CVE-2019-1732","title":"Cisco NX-OS Software Remote Package Manager Command Injection Vulnerability","description":"A vulnerability in the Remote Package Manager (RPM) subsystem of Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to leverage a time-of-check, time-of-use (TOCTOU) race condition to corrupt local variables, which could lead to arbitrary command injection.
