To be protected, web admins should update the patched version of the plugin, 5.153.4. РІР‚СљDespite these obstacles, we were able to craft a proof-of-concept capable of extracting data from anywhere in the database by sending requests containing SQL commands in the user-agent request header,РІР‚Сњ researchers said. РІР‚СљSince data was not being inserted into a sensitive table, the insert query could not be used by an attacker to exploit the site by changing values in the database, and this also made it difficult to retrieve any sensitive data from the database,РІР‚Сњ according to Wordfence.Р”Р„lso, the SQL statement used the РІР‚Сљsanitize_text_fieldРІР‚Сњ function in an attempt to prevent SQL injection, and the user-agent was included in the query within single quotes. For instance, the vulnerable SQL query is an РІР‚СљinsertРІР‚Сњ query. Wordfence did outline several features in the plugin code that make the issue more difficult to exploit. РІР‚СљThere are a number of other SQL-injection techniques that can work around many forms of traditional input sanitization depending on the exact construction of the vulnerable query.РІР‚Сњ РІР‚СљFor example, a request might ask the database if the first letter of the admin userРІР‚в„ўs email address starts with the letter РІР‚Вc,РІР‚в„ў and instruct it to delay the response by five seconds if this is true, and then try guessing the next letters in sequence,РІР‚Сњ according to Wordfence. This is an approach that involves sending requests to the database that РІР‚СљguessРІР‚Сњ at the content of a database table and instruct the database to delay the response or РІР‚СљsleepРІР‚Сњ if the guess is correct. Researchers were able to successfully exploit the vulnerability in CleanTalk via the time-based blind SQL-injection technique, they said.

Prepared statements are one of the ways to prevent this they isolate each query parameter so that an adversary would not be able to see the entire scope of the data thatРІР‚в„ўs returned.

SQL injection is a web-security vulnerability that allows attackers to interfere with the queries that an application makes to its database, so that they intercept or infer the responses that databases return when queried.

РІР‚СљUnfortunately, the update_log function in lib/Cleantalk/ApbctWP/Firewall/SFW.php, which was used to insert records of these requests into the database, failed to use a prepared SQL statement,РІР‚Сњ according to the firm, which released an analysis on Tuesday. It maintains a blocklist and tracks the behavior of different IP addresses, including the user-agent string that browsers send to identify themselves.
