Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail 1.4.21 and earlier allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) drop-down selection lists, (2) the > (greater than) character in the SquirrelSpell spellchecking plugin, and (3) errors associated with the Index Order (aka options_order) page.

Security readout for executives and security teams

CVE-2010-4555 is a set of cross-site scripting issues in SquirrelMail 1.4.21 and earlier. If exposed webmail is vulnerable, an attacker could cause malicious script or HTML to run in a user’s browser in the SquirrelMail context. Exposure is likely limited to organizations still running SquirrelMail 1.4.21 or earlier, or distribution packages based on vulnerable code. Internet-facing webmail, shared hosting, legacy mail portals, and deployments using SquirrelSpell deserve priority review. Treat this as a legacy webmail hygiene issue with moderate business urgency. Prioritize if SquirrelMail is internet-facing, used by privileged staff, or still active in hosting environments. The main risk is browser-side compromise within a trusted mail session. Mitigation focus: Identify any SquirrelMail deployment and confirm its exact upstream or distribution package version.; Apply the relevant vendor security update from SquirrelMail, Debian, Red Hat, Mandriva, Apple, or your platform vendor.; Disable or restrict legacy SquirrelMail access if timely patching is not possible..
