[GLSA-200603-09] SquirrelMail: Cross-site scripting and IMAP command injection

Vulnerability Assessment Summary SquirrelMail: Cross-site scripting and IMAP command injection Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200603-09 (SquirrelMail: Cross-site scripting and IMAP command injection) SquirrelMail does not validate the right_frame parameter in webmail.php, possibly permiting frame replacement or cross-site scripting (CVE-2006-0188). Martijn Brinkers and Scott Hughes discovered that MagicHTML fails to handle certain input correctly, potentially leading to cross-site scripting (only Internet Explorer, CVE-2006-0195). Vicente Aguilera reported that the sqimap_mailbox_select function did not strip newlines from the mailbox or subject parameter, possibly permiting IMAP command injection (CVE-2006-0377). Impact By exploiting the cross-site scripting vulnerabilities, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's webmail account, cookie theft, etc. A remote attacker could exploit the IMAP command injection to execute arbitrary IMAP commands on the configured IMAP server. Workaround There is no known workaround at this time.
