This vulnerability is due to the .NET Agent Coordinator Service executing code with SYSTEM privileges. An attacker with local access to a device that is running the vulnerable agent could create a custom process that would be launched with those SYSTEM privileges. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system. This vulnerability is fixed in AppDynamics .NET Agent Release 21.7.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-269"],"references":["https://docs.appdynamics.com/display/PAA/Security+Advisory%3A+AppDynamics+.NET+Agent+Privilege+Escalation+Vulnerability","https://docs.appdynamics.com/display/PAA/Security+Advisory%3A+AppDynamics+.NET+Agent+Privilege+Escalation+Vulnerability"],"products":["cisco:appdynamics_.net_agent"],"source":"nvd","synced_at":"2026-10-19T21:21:57.125947417+00:00"},"epss":{"cve":"CVE-2021-34745","score":0.0023,"percentile":0.13929,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
