At Impress IT Solutions, we prioritize safeguarding your business against emerging threats. Recently, significant security vulnerabilities were identified in Microsoft Dynamics 365 and Power Apps Web API, which could have led to sensitive data exposure. These vulnerabilities, uncovered by cybersecurity experts and patched as of May 2024, underscore the importance of proactive IT management for Houston businesses.
Understanding the Vulnerabilities
The three vulnerabilities—two within Power Platform’s OData Web API Filter and one in the FetchXML API—posed serious risks to companies using these tools. Without timely intervention, these flaws could have been exploited to access sensitive data such as names, phone numbers, addresses, financial information, and even password hashes.
- OData Web API Filter Access Control Flaw
The first vulnerability stemmed from insufficient access control, enabling unauthorized access to the contacts table. Threat actors could execute a boolean-based search to extract password hashes character by character, potentially compromising entire datasets.
For example, attackers could query the system using incremental searches like startswith(adx_identity_passwordhash, ‘a’) and refine their search until the full password hash was obtained.
- Orderby Clause Exploitation
The second flaw leveraged the orderby clause in the OData Web API, allowing attackers to retrieve specific columns of data, such as email addresses, without proper authorization. - FetchXML API Vulnerability
The third issue involved the FetchXML API, which allowed attackers to bypass existing access controls and retrieve restricted data columns using custom queries. Unlike the other vulnerabilities, this method offered more flexibility, making it particularly dangerous.
The Implications for Houston Businesses
Exploiting these vulnerabilities could have devastating consequences, including unauthorized access to sensitive information, cracked passwords, and the potential sale of compromised data on the dark web. For businesses in Houston, this highlights the critical need for robust IT security measures.
