CVE-2021-1132 is a high-severity vulnerability affecting Cisco Network Services Orchestrator (NSO) due to improper input validation in its web-management interface and HTTP-based APIs. An unauthenticated, remote attacker can exploit this by sending crafted HTTP requests with directory traversal sequences. This allows access to sensitive files on the affected system, as indicated by its CVSS score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). While Cisco has released software updates, there are no known workarounds, and there is no evidence of active exploitation, public exploit code, or significant community discussion.
