| CVE-2020-14933 | 1 Squirrelmail | 1 Squirrelmail | 2021-11-30 | 6.5 MEDIUM | 8.8 HIGH |
| ** DISPUTED ** compose.php in SquirrelMail 1.4.22 calls unserialize for the $attachments value, which originates from an HTTP POST request. NOTE: the vendor disputes this because these two conditions for PHP object injection are not satisfied: existence of a PHP magic method (such as __wakeup or __destruct), and any attack-relevant classes must be declared before unserialize is called (or must be autoloaded). . | |||||
| CVE-2012-5623 | 1 Squirrelmail | 1 Change Passwd | 2020-03-10 | 5.0 MEDIUM | 7.5 HIGH |
| Squirrelmail 4.0 uses the outdated MD5 hash algorithm for passwords. | |||||
| CVE-2018-8741 | 2 Debian, Squirrelmail | 2 Debian Linux, Squirrelmail | 2019-08-15 | 6.5 MEDIUM | 8.8 HIGH |
| A directory traversal flaw in SquirrelMail 1.4.22 allows an authenticated attacker to exfiltrate (or potentially delete) files from the hosting server, related to ../ in the att_local_name field in Deliver.class.php. | |||||
| CVE-2017-7692 | 1 Squirrelmail | 1 Squirrelmail | 2017-11-04 | 9.0 HIGH | 8.8 HIGH |
| SquirrelMail 1.4.22 (and other versions before 20170427_0200-SVN) allows post-authentication remote code execution via a sendmail.cf file that is mishandled in a popen call. It's possible to exploit this vulnerability to execute arbitrary shell commands on the remote server. The problem is in the Deliver_SendMail.class.php with the initStream function that uses escapeshellcmd() to sanitize the sendmail command before executing it. The use of escapeshellcmd() is not correct in this case since it doesn't escape whitespaces, allowing the injection of arbitrary command parameters. The problem is in -f$envelopefrom within the sendmail command line. Hence, if the target server uses sendmail and SquirrelMail is configured to use it as a command-line program, it's possible to trick sendmail into using an attacker-provided configuration file that triggers the execution of an arbitrary command. For exploitation, the attacker must upload a sendmail.cf file as an email attachment, and inject the sendmail.cf filename with the -C option within the "Options > Personal Informations > Email Address" setting. | |||||
