Squirrelmail : Security Vulnerabilities, CVEs, Published In 2006 (XSS) CVSS score >= 3

Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail 1.4.0 through 1.4.9 allow remote attackers to inject arbitrary web script or HTML via the (1) mailto parameter in (a) webmail.php, the (2) session and (3) delete_draft parameters in (b) compose.php, and (4) unspecified vectors involving "a shortcoming in the magicHTML filter."

SquirrelMail 1.4.6 and earlier, with register_globals enabled, allows remote attackers to hijack cookies in src/redirect.php via unknown vectors. NOTE: while "cookie theft" is frequently associated with XSS, the vendor disclosure is too vague to be certain of this.

Interpretation conflict in the MagicHTML filter in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to conduct cross-site scripting (XSS) attacks via style sheet specifiers with invalid (1) "/*" and "*/" comments, or (2) a newline in a "url" specifier, which is processed by certain web browsers including Internet Explorer.

webmail.php in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to inject arbitrary web pages into the right frame via a URL in the right_frame parameter. NOTE: this has been called a cross-site scripting (XSS) issue, but it is different than what is normally identified as XSS.
