CVE-2017-12796
CriticalSummary
The Reporting Compatibility Add On before 2.0.4 for OpenMRS does not authenticate users when deserializing XML input into ReportSchema objects. This allows remote unauthenticated users to execute operating system commands by crafting malicious XML payloads.
Risk Assessment
The organization is at serious risk as an attacker can gain access to the operating system and execute arbitrary commands, potentially leading to data loss or system takeover.
Recommendation
It is recommended to update the Reporting Compatibility Add On to version 2.0.4 or later and implement authentication mechanisms for all XML data deserialization operations.
Original NVD description (English source)
The Reporting Compatibility Add On before 2.0.4 for OpenMRS, as distributed in OpenMRS Reference Application before 2.6.1, does not authenticate users when deserializing XML input into ReportSchema objects. The result is that remote unauthenticated users are able to execute operating system commands by crafting malicious XML payloads, as demonstrated by a single admin/reports/reportSchemaXml.form request.
