Vulnerability Assessment Details
Multiple XSS Vulnerabilities in SquirrelMail
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200405-16
(Multiple XSS Vulnerabilities in SquirrelMail)
Several unspecified cross-site scripting (XSS) vulnerabilities and a well
hidden SQL injection vulnerability were found. An XSS attack permits an
attacker to insert malicious code into a web-based application.
SquirrelMail does not check for code when parsing variables received via
the URL query string.
One of the XSS vulnerabilities could be exploited by a possible hacker to steal
cookie-based authentication credentials from the user's browser. The SQL
injection issue could potentially be used by a possible hacker to run arbitrary
SQL commands inside the SquirrelMail database with rights of the
SquirrelMail database user.
There is no known workaround at this time. All users are advised to upgrade
to version 1.4.3_rc1 or higher of SquirrelMail.
All SquirrelMail users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-mail/squirrelmail-1.4.3_rc1"
# emerge ">=net-mail/squirrelmail-1.4.3_rc1"
Network Security Threat Level: Medium
