CVE-2020-12677 — An issue was discovered in Progress MOVEit Automation Web Admin
An issue was discovered in Progress MOVEit Automation Web Admin. A Web Admin application endpoint failed to adequately sanitize malicious input, which could allow an unauthenticated attacker to execute arbitrary code in a victim's browser, aka XSS. This affects 2018 - 2018.0 prior to 2018.0.3, 2018 SP1 - 2018.2 prior to 2018.2.3, 2018 SP2 - 2018.3 prior to 2018.3.7, 2019 - 2019.0 prior to 2019.0.3, 2019.1 - 2019.1 prior to 2019.1.2, and 2019.2 - 2019.2 prior to 2019.2.2.

Matched remediation archetype
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.
