How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-15887, inspect your project dependencies for Munkireport/softwareupdate:

inspect dependencies for munkireport/softwareupdate

Analyze the terminal output to locate any version of Munkireport/softwareupdate in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Munkireport/softwareupdate, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A SQL injection vulnerability in softwareupdate_controller.php in the Software Update module before 1.6 for MunkiReport allows attackers to execute arbitrary SQL commands via the last URL parameter of the `/module/softwareupdate/get_tab_data/` endpoint.
