MOVEit, the file-transfer software exploited in recent weeks in one of the biggest cyberattacks ever, has received yet another security update that fixes a critical vulnerability that could be exploited to give hackers access to vast amounts of sensitive data.
On Thursday, MOVEit maker Progress Software published a security bulletin that included fixes for three newly discovered vulnerabilities in the file-transfer application. The most serious of them, tracked as CVE-2023-36934, allows an unauthenticated attacker to gain unauthorized access to the application database. It stems from a security flaw that allows for SQL injection, one of the oldest and most common exploit classes.
The vulnerability contains the same elements—and, likely, the same potentially devastating consequences—as one that came to light in late May when members of the Clop ransomware crime syndicate began mass-exploiting it on vulnerable networks around the world. To date, the Clop offensive has hit 229 organizations and spilled data affecting more than 17 million people, according to statistics tracked by Brett Callow, an analyst with security firm Emsisoft. Casualties include Louisiana and Oregon DMVs, the New York City Department of Education, and energy companies Schneider Electric and Siemens Electric.
