Vulnerabilities (CVE)

The spell checker plugin (check_me.mod.php) for SquirrelMail before 1.2.3 allows remote attackers to execute arbitrary commands via a modified sqspell_command parameter.

Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail before 1.2.11 allow remote attackers to inject arbitrary HTML code and steal information from a client's web browser.

Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail 1.4.0 through 1.4.4 allow remote attackers to inject arbitrary web script or HTML via unknown attack vectors in (1) the URL or (2) an e-mail message.

Cross-site scripting (XSS) vulnerability in read_body.php in SquirrelMail before 1.2.3 allows remote attackers to execute arbitrary Javascript via a javascript: URL in an IMG tag.

Interpretation conflict in the MagicHTML filter in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to conduct cross-site scripting (XSS) attacks via style sheet specifiers with invalid (1) "/*" and "*/" comments, or (2) a newline in a "url" specifier, which is processed by certain web browsers including Internet Explorer.

An incomplete fix for a cross-site scripting (XSS) vulnerability in SquirrelMail 1.2.8 calls the strip_tags function on the PHP_SELF value but does not save the result back to that variable, leaving it open to cross-site scripting attacks.

Cross-site scripting (XSS) vulnerability in webmail.php in SquirrelMail before 1.4.4 allows remote attackers to inject arbitrary web script or HTML via certain integer variables.

SquirrelMail 1.4.6 and earlier, with register_globals enabled, allows remote attackers to hijack cookies in src/redirect.php via unknown vectors. NOTE: while "cookie theft" is frequently associated with XSS, the vendor disclosure is too vague to be certain of this.

SquirrelMail 1.2.7 and earlier allows remote attackers to determine the absolute pathname of the options.php script via a malformed optpage file argument, which generates an error message when the file cannot be included in the script.

webmail.php in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to inject arbitrary web pages into the right frame via a URL in the right_frame parameter. NOTE: this has been called a cross-site scripting (XSS) issue, but it is different than what is normally identified as XSS.

Cross-site scripting (XSS) vulnerability in the decoding of encoded text in certain headers in mime.php for SquirrelMail 1.4.3a and earlier, and 1.5.1-cvs before 23rd October 2004, allows remote attackers to execute arbitrary web script or HTML.

PHP remote file inclusion vulnerability in functions/plugin.php in SquirrelMail 1.4.6 and earlier, if register_globals is enabled and magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary PHP code via a URL in the plugins array parameter. NOTE: this issue has been disputed by third parties, who state that Squirrelmail provides prominent warnings to the administrator when register_globals is enabled.

PHP remote file inclusion vulnerability in functions/plugin.php in SquirrelMail 1.4.6 and earlier, if register_globals is enabled and magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary PHP code via a URL in the plugins array parameter. NOTE: this issue has been disputed by third parties, who state that Squirrelmail provides prominent warnings to the administrator when register_globals is enabled. Since the varieties of administrator negligence are uncountable, perhaps this type of issue should not be included in CVE. However, the original developer has posted a security advisory, so there might be relevant real-world environments under which this vulnerability is applicable

Dynamic variable evaluation vulnerability in compose.php in SquirrelMail 1.4.0 to 1.4.7 allows remote attackers to overwrite arbitrary program variables and read or write the attachments and preferences of other users.

SquirrelMail 1.2.5 and earlier allows authenticated SquirrelMail users to execute arbitrary commands by modifying the THEME variable in a cookie.

load_prefs.php and supporting include files in SquirrelMail 1.0.4 and earlier do not properly initialize certain PHP variables, which allows remote attackers to (1) view sensitive files via the config_php and data_dir options, and (2) execute arbitrary code by using options_order.php to upload a message that could be interpreted as PHP.

Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail 1.4.2 allow remote attackers to execute arbitrary script as other users and possibly steal authentication information via multiple attack vectors, including the mailbox parameter in compose.php.

CRLF injection vulnerability in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to inject arbitrary IMAP commands via newline characters in the mailbox parameter of the sqimap_mailbox_select command, aka "IMAP injection."

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).

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.

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 NOEMBED, NOFRAMES, NOSCRIPT, or TEXTAREA element.

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.

The mail message display page in SquirrelMail through 1.4.22 has XSS via SVG animations (animate to attribute).

The mail message display page in SquirrelMail through 1.4.22 has XSS via the formaction attribute.

The mail message display page in SquirrelMail through 1.4.22 has XSS via a "<math xlink:href=" attack.

The mail message display page in SquirrelMail through 1.4.22 has XSS via a "<math><maction xlink:href=" attack.

The mail message display page in SquirrelMail through 1.4.22 has XSS via a "<form action='data:text" attack.

The mail message display page in SquirrelMail through 1.4.22 has XSS via a "<svg><a xlink:href=" attack.
