CVE-2018-25199 in OOP CMS BLOG
Summary
by MITRE • 03/06/2026
OOP CMS BLOG 1.0 contains SQL injection vulnerabilities that allow unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through multiple parameters. Attackers can inject SQL commands via the search parameter in search.php, pageid parameter in page.php, and id parameter in posts.php to extract database information including table names, schema names, and database credentials.

The vulnerability identified as CVE-2018-25199 represents a critical SQL injection flaw within OOP CMS BLOG version 1.0 that exposes the application to unauthorized database access. This vulnerability stems from inadequate input validation and sanitization mechanisms within the CMS's core components, specifically affecting three distinct entry points that process user-supplied data without proper security measures. The flaw allows unauthenticated attackers to manipulate the underlying database through carefully crafted malicious inputs that bypass normal application logic and directly interact with the database engine.
The technical implementation of this vulnerability occurs through three primary attack vectors that all share the common weakness of insufficient parameter sanitization. The search parameter in search.php serves as one entry point where malicious SQL code can be injected, enabling attackers to execute arbitrary database commands against the system's backend. Similarly, the pageid parameter in page.php and the id parameter in posts.php both present opportunities for SQL injection attacks, as they accept user input without proper validation or escaping mechanisms. These parameters are directly incorporated into SQL query strings without appropriate sanitization, creating a pathway for attackers to manipulate the database structure and extract sensitive information.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with comprehensive access to the database contents through multiple extraction techniques. Attackers can leverage the SQL injection to enumerate database schema information, including table names, column structures, and database user credentials. This level of access enables further exploitation activities such as privilege escalation, data manipulation, and potential lateral movement within the network infrastructure. The vulnerability's unauthenticated nature means that any user with access to the web application can exploit these flaws without requiring prior authorization or credentials, significantly increasing the attack surface and potential damage.
From a cybersecurity framework perspective, this vulnerability maps directly to CWE-89 which specifically addresses SQL injection vulnerabilities in software applications. The flaw also aligns with several ATT&CK tactics including TA0001 Initial Access and TA0002 Execution, as attackers can use this vulnerability to gain initial system access and execute malicious database commands. The vulnerability's classification as unauthenticated SQL injection places it within the high-risk category of web application flaws that require immediate remediation. Organizations utilizing this CMS version face significant exposure to data breaches, system compromise, and potential regulatory violations due to the sensitive nature of the information that can be extracted through these attacks.
Mitigation strategies for CVE-2018-25199 require immediate implementation of input validation and parameterized query approaches across all affected application components. The most effective solution involves updating the CMS to a patched version that implements proper input sanitization and uses prepared statements or parameterized queries to prevent SQL injection attacks. Organizations should also implement web application firewalls to detect and block malicious SQL injection attempts, while conducting comprehensive security audits to identify additional vulnerable parameters. Regular security updates and patch management processes should be established to prevent similar vulnerabilities from emerging in the future, with particular attention to legacy systems that may contain outdated code structures that are susceptible to these types of attacks.
