CVE-2020-7356 — CAYIN xPost suffers from an unauthenticated SQL Injection vulnerability
Critical
CVSS 10
CAYIN xPost suffers from an unauthenticated SQL Injection vulnerability. Input passed via the GET parameter 'wayfinder_seqid' in wayfinder_meeting_input.jsp is not properly sanitized before being returned to the user or used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code and execute SYSTEM commands.

Matched remediation archetype
SQL and data-query injection
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace request, message, file, and stored values into SQL, ORM query fragments, filters, sort expressions, and other data-query languages.
- Inventory database roles, reachable schemas, multi-tenant boundaries, and whether stacked or administrative operations are enabled.
- Check both direct queries and second-order use of previously stored values.
Remediate safely
- Use parameterized queries or safe query builders for all values; map identifiers and operators through explicit allowlists.
- Remove raw query concatenation and give the application account only the tables and operations it requires.
- Update affected data-access components and add regression tests for query structure preservation with inert edge-case inputs.
