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.", "severity": [], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2020-24046" }, { "type": "WEB", "url": "https://github.com/felmoltor" }, { "type": "WEB", "url": "https://sensepost.com/blog/2020/clash-of-the-spamtitan" }, { "type": "WEB", "url": "https://twitter.com/felmoltor" }, { "type": "WEB", "url": "https://www.titanhq.com" } ], "database_specific": { "cwe_ids": [], "severity": "HIGH", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2020-09-17T17:15:00Z" } }
