It limits the admin user to a restricted shell, allowing execution of a small number of tools of the operating system. This restricted shell can be bypassed after changing the properties of the user admin in the operating system file /etc/passwd. This file cannot be accessed though the restricted shell, but it can be modified by abusing the Backup/Import Backup functionality of the web interface. An authenticated attacker would be able to obtain the file /var/tmp/admin.passwd after executing a Backup operation. This file can be manually modified to change the GUID of the user to 0 (root) and change the restricted shell to a normal shell /bin/sh. After the modification is done, the file can be recompressed to a .tar.bz file and imported again via the Import Backup functionality. The properties of the admin user will be overwritten and a root shell will be granted to the user upon the next successful login.","state":"PUBLIC","assigner":"cve@mitre.org","published_at":"2020-09-17 17:15:00","updated_at":"2020-09-24 13:46:00"},"problem_types":["CWE-269"],"metrics":[],"references":[{"url":"https://sensepost.com/blog/2020/clash-of-the-spamtitan/","name":"https://sensepost.com/blog/2020/clash-of-the-spamtitan/","refsource":"MISC","tags":["Exploit","Third Party Advisory"],"title":"SensePost |   Clash of the (spam)titan","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.titanhq.com","name":"https://www.titanhq.com","refsource":"MISC","tags":["Vendor Advisory"],"title":"titanhq.com","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://twitter.com/felmoltor","name":"https://twitter.com/felmoltor","refsource":"MISC","tags":["Third Party Advisory"],"title":"Felipe Molina (felmoltor) on Twitter","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://github.com/felmoltor","name":"https://github.com/felmoltor","refsource":"MISC","tags":["Third Party Advisory"],"title":"felmoltor (Felipe Molina) · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2020-24046","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-24046","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2020","cve_id":"24046","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"titanhq","cpe5":"spamtitan","cpe6":"7.07","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2020","cve_id":"24046","vulnerable":"1","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"titanhq","cpe5":"spamtitan","cpe6":"7.07","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"cve@mitre.org","ID":"CVE-2020-24046","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"n/a","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"n/a"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"A sandbox escape issue was discovered in TitanHQ SpamTitan Gateway 7.07.
