    Hi there,

    (report below)

    Just wondering if anybody knows how cpanel handles security issues like this one. Squirrel mail just released a new update and then within a day an update with the fix, however the XSS vulnerabilites are reported for versions 1.x.

    What should we do?


    TITLE:
    SquirrelMail Multiple Cross-Site Scripting Vulnerabilities

    SECUNIA ADVISORY ID:
    SA23195

    VERIFY ADVISORY:
    http://secunia.com/advisories/23195/

    CRITICAL:
    Moderately critical

    IMPACT:
    Cross Site Scripting

    WHERE:
    From remote

    SOFTWARE:
    SquirrelMail 1.x
    http://secunia.com/product/288/

    DESCRIPTION:
    Some vulnerabilities have been reported in SquirrelMail, which can be exploited by malicious people to conduct cross-site scripting and script insertion attacks.

    1) Input passed to certain parameters in webmail.php and compose.php in the "draft", "compose", and "mailto" functionality is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

    2) Input validation errors exist in the magicHTML filter when sanitising HTML mails. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.

    Successful exploitation of some of these errors require that the target user runs Microsoft Internet Explorer.

    The vulnerabilities are reported in versions before 1.4.9a.

    SOLUTION:
    Update to version 1.4.9a.

    PROVIDED AND/OR DISCOVERED BY:
    The vendor credits Martijn Brinkers

    ORIGINAL ADVISORY: http://squirrelmail.org/security/issue/2006-12-02
    http://sourceforge.net/project/shownotes.php?release_id=468482

    Hi,

    this is a hot issue in the netherlands, because it is discovered there in a servey to check the level of security of webmail of internet providers.

    I think cpanel would pick up the problem if we make a report in bugzilla, but it will take long (to long for a dutch provider ;))

    So has someone a guide to manually update squirrelmail to the latest version (1.4.9a)
