Multiple cross-site request forgery (CSRF) vulnerabilities in SquirrelMail 1.4.19 and earlier, and NaSMail before 1.7, allow remote attackers to hijack the authentication of unspecified victims via features such as send message and change preferences, related to (1) functions/mailbox_display.php, (2) src/addrbook_search_html.php, (3) src/addressbook.php, (4) src/compose.php, (5) src/folders.php, (6) src/folders_create.php, (7) src/folders_delete.php, (8) src/folders_rename_do.php, (9) src/folders_rename_getname.php, (10) src/folders_subscribe.php, (11) src/move_messages.php, (12) src/options.php, (13) src/options_highlight.php, (14) src/options_identities.php, (15) src/options_order.php, (16) src/search.php, and (17) src/vcard.php.

From Red Hat Security Advisory 2009:1490 :

An updated squirrelmail package that fixes several security issues is now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

SquirrelMail is a standards-based webmail package written in PHP.

Form submissions in SquirrelMail did not implement protection against Cross-Site Request Forgery (CSRF) attacks. If a remote attacker tricked a user into visiting a malicious web page, the attacker could hijack that user's authentication, inject malicious content into that user's preferences, or possibly send mail without that user's permission. (CVE-2009-2964)

Users of SquirrelMail should upgrade to this updated package, which contains a backported patch to correct these issues.

CVE-2009-2964 squirrelmail: CSRF issues in all forms

Form submissions in SquirrelMail did not implement protection against Cross-Site Request Forgery (CSRF) attacks. If a remote attacker tricked a user into visiting a malicious web page, the attacker could hijack that user's authentication, inject malicious content into that user's preferences, or possibly send mail without that user's permission. (CVE-2009-2964)

SquirrelMail, a webmail application, does not employ a user-specific token for webforms. This allows a remote attacker to perform a Cross Site Request Forgery (CSRF) attack. The attacker may hijack the authentication of unspecified victims and send messages or change user preferences among other actions, by tricking the victim into following a link controlled by the offender.

In addition, a denial-of-service was fixed, which could be triggered when a password containing 8-bit characters was used to log in (CVE-2010-2813 ).
