Cross-site request forgery (CSRF) vulnerability in SquirrelMail 1.4.8-4.fc6 and earlier allows remote attackers to perform unspecified actions as arbitrary users via unspecified vectors. NOTE: this issue might overlap CVE-2007-2589 or CVE-2002-1648.

Cross-site scripting (XSS) vulnerability in search.php in SquirrelMail 1.5.1 and earlier, when register_globals is enabled, allows remote attackers to inject arbitrary HTML via the mailbox parameter.

** DISPUTED ** 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.

options_identities.php in SquirrelMail 1.4.4 and earlier uses the extract function to process the $_POST variable, which allows remote attackers to modify or read the preferences of other users, conduct cross-site scripting XSS) attacks, and write arbitrary files.

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.
