Description

The WP-Partner WordPress plugin through 1.2.1 does not sanitise and escape a parameter before using it in a SQL query, allowing unauthenticated attackers to append additional SQL queries and extract sensitive information from the database.

  "executiveSummary": "The WP-Partner plugin, in all versions up to and including 1.2.1, contains a critical SQL injection vulnerability.\nThis vulnerability exists due to improper sanitization and escaping of user-supplied input before it is incorporated into database queries.\nThe flaw permits unauthenticated, remote attackers to execute arbitrary SQL commands against the backend database.\nSuccessful exploitation results in unauthorized data access, including the potential extraction of sensitive information, database credentials, or administrative user data.\nGiven that the attack does not require prior authentication, the risk is classified as critical, as it allows attackers to bypass standard application security controls.\nThe vulnerability directly impacts the integrity and confidentiality of the WordPress database managed by the affected plugin.",
  "technicalDetails": "The root cause of this vulnerability is a failure to implement secure coding practices regarding database interactions within the WP-Partner plugin versions 1.2.1 and earlier.\nSpecifically, the plugin accepts user-supplied input via an HTTP request parameter that is subsequently concatenated directly into a SQL query string without prior validation, sanitization, or the use of parameterized prepared statements.\nBy injecting specially crafted SQL syntax into the vulnerable parameter, an attacker can manipulate the structure of the original query.\nBecause the application fails to utilize WordPress's built-in database abstraction layer (such as the $wpdb->prepare() function), the database engine interprets the malicious input as part of the executable command rather than as a literal data value.\nThe attack flow begins when an unauthenticated actor sends a crafted request containing SQL injection payloads, such as UNION-based or time-based blind SQL injection strings, to the affected endpoint.\nUpon receiving the malicious payload, the plugin executes the query in the context of the WordPress database user. This grants the attacker the ability to perform unauthorized operations, including dumping sensitive tables, modifying user permissions, or potentially escalating privileges.\nIn a UNION-based attack scenario, the attacker can append a UNION SELECT statement to the original query to force the application to return data from arbitrary tables within the database, effectively leaking database structure and contents.\nIf the database user has elevated permissions, the attacker might also leverage this vulnerability to interact with the underlying filesystem or operating system, depending on the specific configuration of the database environment.\nThe vulnerability is accessible over the network without requiring any prior authentication, making it a highly attractive target for automated exploitation tools that scan for vulnerable WordPress plugins.\nThe lack of input filtering at the application entry point ensures that any string containing SQL control characters, such as single quotes, semicolons, or comments (e.g., --, #), can trigger the vulnerability, leading to full compromise of the database integrity."
