{"id":"CVE-2023-34409","details":"In Percona Monitoring and Management (PMM) server 2.x before 2.37.1, the authenticate function in auth_server.go does not properly formalize and sanitize URL paths to reject path traversal attempts. This allows an unauthenticated remote user, when a crafted POST request is made against unauthenticated API routes, to access otherwise protected API routes leading to escalation of privileges and information disclosure.","modified":"2026-07-15T01:48:55.397038089Z","published":"2023-06-06T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/34xxx/CVE-2023-34409.json","unresolved_ranges":[{"source":"DESCRIPTION","extracted_events":[{"introduced":"2.x"},{"fixed":"2.37.1"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/34xxx/CVE-2023-34409.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34409"},{"type":"ARTICLE","url":"https://www.percona.com/blog/pmm-authentication-bypass-vulnerability-fixed-in-2-37-1/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/percona/pmm","events":[{"introduced":"94232076c12a4511f4f1d48988b56ab2bfd24286"},{"fixed":"03b95b3d05401a268eda3158db739f5f11a619de"}],"database_specific":{"extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.37.1"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:percona:monitoring_and_management:*:*:*:*:*:*:*:*"}}],"versions":["v2.37.0","v2.28.0","v2.27.0","v2.26.0","v2.25.0","v2.24.0","v2.23.0","v2.22.0","v2.21.0","v2.20.0","v2.19.0","v2.18.0","v2.17.0","v2.16.0","v2.15.1","v2.15.0","v2.14.0","v2.13.0","v2.12.0","v2.11.1","v2.11.0","v2.10.1","v2.10.0","v2.9.1","v2.9.0","v2.8.0","v2.7.0","v2.6.1","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.2","v2.2.1","v2.2.0","v2.1.0","v2.0.1","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-34409.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
