Vulnerabilities

mime.php in SquirrelMail through 1.4.23-svn-20250401 and 1.5.x through 1.5.2-svn-20250401 allows XSS via e-mail headers, because JavaScript payloads are mishandled after $encoded has been set to true.

An information exposure vulnerability has been found, the exploitation of which could allow a remote user to retrieve sensitive information stored on the server such as credential files, configuration files, application files, etc., simply by appending any of the following parameters to the end of the URL: %00 %0a,…

Stored XSS vulnerability. This vulnerability could allow an attacker to store a malicious JavaScript payload via GET and POST methods on multiple parameters in the MailAdmin_dll.htm file.

Path traversal vulnerability whose exploitation could allow an authenticated remote user to bypass SecurityManager's intended restrictions and list a parent directory via any filename, such as a multiple ..%2F value affecting the 'dodoc' parameter in the /MailAdmin_dll.htm file.

compose.php in SquirrelMail 1.4.22 calls unserialize for the $attachments value, which originates from an HTTP POST request.

compose.php in SquirrelMail 1.4.22 calls unserialize for the $mailtodata value, which originates from an HTTP GET request. This is related to mailto.php.

Squirrelmail 4.0 uses the outdated MD5 hash algorithm for passwords.

XSS was discovered in SquirrelMail through 1.4.22 and 1.5.x through 1.5.2. Due to improper handling of RCDATA and RAWTEXT type elements, the built-in sanitization mechanism can be bypassed. Malicious script content from HTML e-mail can be executed within the application context via crafted use of (for example) a…

Directory traversal vulnerability in CREAR AL-Mail32 before 1.13d allows remote attackers to write to arbitrary files via a crafted filename of an attachment.

Cross-site scripting (XSS) vulnerability in Homepage Decorator PerlMailer 3.10 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The Gentoo Nullmailer package before 1.11-r2 uses world-readable permissions for /etc/nullmailer/remotes, which allows local users to obtain SMTP authentication credentials by reading the file.

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…

Multiple cross-site request forgery (CSRF) vulnerabilities in SquirrelMail 1.4.21 and earlier allow remote attackers to hijack the authentication of unspecified victims via vectors involving (1) the empty trash implementation and (2) the Index Order (aka options_order) page, a different issue than CVE-2010-4555.
