CVE-2017-7692 1 Squirrelmail 1 Squirrelmail 2025-04-20 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.

Cross-site scripting (XSS) vulnerability in the Autocomplete plugin before 3.0 for SquirrelMail allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
CVE-2010-4555 1 Squirrelmail 1 Squirrelmail 2025-04-11 4.3 MEDIUM N/A
Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail 1.4.21 and earlier allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) drop-down selection lists, (2) the > (greater than) character in the SquirrelSpell spellchecking plugin, and (3) errors associated with the Index Order (aka options_order) page.
CVE-2012-2124 2 Redhat, Squirrelmail 2 Enterprise Linux, Squirrelmail 2025-04-11 5.0 MEDIUM N/A
functions/imap_general.php in SquirrelMail, as used in Red Hat Enterprise Linux (RHEL) 4 and 5, does not properly handle 8-bit characters in passwords, which allows remote attackers to cause a denial of service (disk consumption) by making many IMAP login attempts with different usernames, leading to the creation of many preference files.

functions/page_header.php in SquirrelMail 1.4.21 and earlier does not prevent page rendering inside a frame in a third-party HTML document, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site.
CVE-2010-1637 4 Apple, Fedoraproject, Redhat and 1 more 7 Mac Os X, Mac Os X Server, Fedora and 4 more 2025-04-11 4.0 MEDIUM 6.5 MEDIUM

CVE-2009-1381 1 Squirrelmail 3 Imap General.php, Squirrelmail, Squirrelmail1.4.19-1 2025-04-09 6.8 MEDIUM N/A
The map_yp_alias function in functions/imap_general.php in SquirrelMail before 1.4.19-1 on Debian GNU/Linux, and possibly other operating systems and versions, allows remote attackers to execute arbitrary commands via shell metacharacters in a username string that is used by the ypmatch program. NOTE: this issue exists because of an incomplete fix for CVE-2009-1579.
CVE-2009-1581 1 Squirrelmail 1 Squirrelmail 2025-04-09 4.3 MEDIUM N/A
functions/mime.php in SquirrelMail before 1.4.18 does not protect the application's content from Cascading Style Sheets (CSS) positioning in HTML e-mail messages, which allows remote attackers to spoof the user interface, and conduct cross-site scripting (XSS) and phishing attacks, via a crafted message.
CVE-2007-3779 1 Squirrelmail 1 Gpg Plugin 2025-04-09 4.3 MEDIUM N/A
PHP local file inclusion vulnerability in gpg_pop_init.php in the G/PGP (GPG) Plugin before 20070707 for Squirrelmail allows remote attackers to include and execute arbitrary local files, related to the MOD parameter.
