CVE-2017-15051 — Teampass Teampass security vulnerability

Medium CVSS 5.4

Multiple stored cross-site scripting (XSS) vulnerabilities in TeamPass before 2.1.27.9 allow authenticated remote attackers to inject arbitrary web script or HTML via the (1) URL value of an item or (2) user log history. To exploit the vulnerability, the attacker must be first authenticated to the application. For the first one, the attacker has to simply inject XSS code within the URL field of a shared item. For the second one however, the attacker must prepare a payload within its profile, and then ask an administrator to modify its profile. From there, whenever the administrator accesses the log, it can be XSS'ed.

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
