On Thursday, Microsoft sent warnings to “Thousands” of the company’s cloud computing customers, explaining that “Intruders could have the ability to read, change or even delete their main databases,” according to a Reuters report published the same day citing a cybersecurity researcher and a copy of the warning email.
Researchers at the cybersecurity company Wiz found the vulnerability in Microsoft Azure’s Cosmos DB database, according to Reuters, and were “Able to access keys that control access to databases held by thousands of companies.” Since Microsoft is unable to change these keys, Reuters said the company emailed customers directing them to make new keys.
The Microsoft warning to customers said the company had “No indication that external entities outside the researcher had access to the primary read-write key,” according to Reuters.
The Wiz team discovered the flaw in Jupyter Notebook earlier this month and alerted Microsoft a few days later and the company was paid $40,000 for finding the vulnerability, according to Reuters.
