A critical flaw in Development Software’s in MOVEit Transfer managed file transfer application has come beneath common exploitation in the wild to consider about vulnerable systems.
The shortcoming, which is nevertheless to be assigned a CVE identifier, relates to a significant SQL injection vulnerability that could direct to escalated privileges and possible unauthorized accessibility to the ecosystem.
“An SQL injection vulnerability has been identified in the MOVEit Transfer web application that could enable an unauthenticated attacker to attain unauthorized entry to MOVEit Transfer’s database,” the firm reported.
“Based on the database engine staying utilized (MySQL, Microsoft SQL Server, or Azure SQL), an attacker may possibly be in a position to infer information about the composition and contents of the database in addition to executing SQL statements that change or delete database components.”
