DESCRIPTION
SquirrelMail[1] is a widely used webmail client for php4.
Four vulnerabilities were discovered in SquirrelMail:
Alvin Alex reported[2] that SquirrelMail 1.4.2 is prone to multiple
cross-site scripting[3] attacks which could 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.
Roman Medina discovered[4] a cross-site scripting (XSS)
vulnerability[5] in mime.php for SquirrelMail before 1.4.3 that
allows remote attackers to insert arbitrary HTML and script code via
the content-type mail header, as demonstrated using read_body.php.
An SQL injection vulnerability[6] in SquirrelMail before 1.4.3 RC1
allows remote attackers to execute unauthorized SQL statements, with
unknown impact, probably via abook_database.php.
Roman Medina also found[7] other multiple cross-site scripting (XSS)
vulnerabilities[8] in SquirrelMail 1.2.10 and earlier that allows
remote attackers to inject arbitrary HTML or script via (a) the
$mailer variable in read_body.php, (b) the $senderNames_part variable
in mailbox_display.php, and possibly other vectors including (c) the
$event_title variable or (d) the $event_text variable.
SOLUTION
It is recommended that all SquirrelMail users upgrade their
packages.
