Description

The cacheservice API could be abused to inject parameters with SQL syntax which was insufficiently sanitized before getting executed as SQL statement. Attackers with access to a local or restricted network were able to perform arbitrary SQL queries, discovering other users cached data. We have improved the input check for API calls and filter for potentially malicious content. No publicly available exploits are known.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
