Last modified

CVE-2021-1132 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A vulnerability in the API subsystem and in the web-management interface of Cisco Network Services Orchestrator (NSO) could allow an unauthenticated, remote attacker to access sensitive data. This vulnerability exists because the web-management interface and certain HTTP-based APIs do not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. EPSS estimates a 1.61% chance of exploitation in the next 30 days.
