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.","publishedAt":"2020-09-17T16:39:31.000Z","updatedAt":"2024-08-04T15:05:11.914Z","severity":null,"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://github.com/felmoltor","https://twitter.com/felmoltor","https://www.titanhq.com","https://sensepost.com/blog/2020/clash-of-the-spamtitan/"],"weaknesses":[],"ingestedAt":"2026-10-29T19:47:03.086Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/24xxx/CVE-2020-24046.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2020-24046","state":"PUBLISHED","datePublished":"2020-09-17T16:39:31.000Z","dateUpdated":"2024-08-04T15:05:11.914Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2020-08-13T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"A sandbox escape issue was discovered in TitanHQ SpamTitan Gateway 7.07.
