CVE-2015-9276: SmarterTools SmarterMail before 13.3.5535 was vulnerable to stored XSS by bypassing the anti-XSS mechanisms.

SmarterTools SmarterMail before 13.3.5535 was vulnerable to stored XSS by bypassing the anti-XSS mechanisms. It was possible to run JavaScript code when a victim user opens or replies to the attacker's email, which contained a malicious payload. Therefore, users' passwords could be reset by using an XSS attack, as the password reset page did not need the current password.

Security readout for executives and security teams

Plain-English summary

Older SmarterMail installations could let an attacker plant script code inside an email. When a user opened or replied to that message, the script could run in their browser. The cited CVE says this could support password reset abuse because the reset page did not require the current password.

Executive priority

Treat as high priority only where legacy SmarterMail is still deployed. The vulnerability is old, but the described impact reaches user account compromise. If SmarterMail is not present, document non-exposure and move on.

Technical view

CVE-2015-9276 is a stored cross-site scripting flaw in SmarterTools SmarterMail before 13.3.5535. The issue bypassed anti-XSS filtering for email content, allowing JavaScript execution in a victim user's session when viewing or replying to a crafted email. The bundle provides no CVSS, CWE, or detailed affected CPE data.

Likely exposure

Exposure is most likely in organizations still running SmarterTools SmarterMail versions before 13.3.5535. The provided affected-product metadata is incomplete, so validation should rely on product inventory and installed version checks.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. Public advisory references exist, and the described impact includes session-context script execution and possible password reset abuse, but no in-the-wild exploitation is cited here.

Researcher notes

Key gaps are absent CVSS, CWE, and structured affected CPE data. The main supported facts are product/version scope from the description and references, stored XSS in email content, trigger on open or reply, and password reset abuse potential.

Mitigation direction

  • Upgrade SmarterMail to 13.3.5535 or later if still on an affected version.
  • Review SmarterTools release notes and advisory guidance for the relevant branch.
  • Prioritize remediation for internet-facing mail portals and administrative users.
  • Require current password or stronger reauthentication for password changes where configurable.

Validation and detection

  • Inventory all SmarterMail deployments and record exact installed versions.
  • Confirm no production instance runs a version earlier than 13.3.5535.
  • Review historical account password-reset events around suspicious email activity.
  • Check whether webmail access is internet-facing or restricted to trusted networks.
  • Verify monitoring covers unusual account changes from webmail sessions.
