CVE-2018-17796 — An issue was discovered in MRCMS (aka mushroom) through 3.1.2

Critical CVSS 9.8

An issue was discovered in MRCMS (aka mushroom) through 3.1.2. The WebParam.java file directly accepts the FIELD_T parameter in a request and uses it as a hash of SQL statements without filtering, resulting in a SQL injection vulnerability in getChannel() in the ChannelService.java file.

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.
