An attacker could exploit this vulnerability by modifying objects in the PHP Agent install directory, which would run with the same privileges as PHP. A successful exploit could allow a lower-privileged attacker to elevate their privileges to root on an affected device.","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://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-appd-php-authpriv-gEBwTvu5","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-appd-php-authpriv-gEBwTvu5"],"products":["cisco:appdynamics"],"source":"nvd","synced_at":"2026-10-19T21:42:07.670898610+00:00"},"epss":{"cve":"CVE-2023-20274","score":0.00187,"percentile":0.08379,"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).
