Detailsinfo

A vulnerability classified as problematic has been found in thorsten phpMyFAQ up to 4.1.0. This affects the function searchCustomPages of the file phpmyfaq/src/phpMyFAQ/Search.php. The manipulation with an unknown input leads to a data query logic injection vulnerability. CWE is classifying the issue as CWE-943. The product generates a query intended to access or manipulate data in a data store such as a database, but it does not neutralize or incorrectly neutralizes special elements that can modify the intended logic of the query. This is going to have an impact on confidentiality. The summary by CVE is:

phpMyFAQ is an open source FAQ web application. Prior to version 4.1.1, the searchCustomPages() method in phpmyfaq/src/phpMyFAQ/Search.php uses real_escape_string() (via escape()) to sanitize the search term before embedding it in LIKE clauses. However, real_escape_string() does not escape SQL LIKE metacharacters % (match any sequence) and _ (match any single character). An unauthenticated attacker can inject these wildcards into search queries, causing them to match unintended records — including content that was not meant to be surfaced — resulting in information disclosure. This issue has been patched in version 4.1.1.
