CVE-2009-2554 in jobline
Summary
by MITRE
SQL injection vulnerability in the search method in jobline.class.php in Jobline (com_jobline) 1.1.2.2, 1.3.1, and possibly earlier versions, a component for Joomla!, allows remote attackers to execute arbitrary SQL commands via the search parameter in a results action to index.php, which invokes the search method from the searchJobPostings function in jobline.php.

The vulnerability described in CVE-2009-2554 represents a critical SQL injection flaw within the Jobline component for Joomla! versions 1.1.2.2, 1.3.1, and potentially earlier releases. This vulnerability resides in the jobline.class.php file within the search method, specifically when processing search parameters through the results action in index.php. The flaw occurs when the search parameter is passed to the searchJobPostings function in jobline.php, creating an exploitable pathway for malicious actors to manipulate database queries. The vulnerability is classified as a classic SQL injection attack vector where user-supplied input is directly incorporated into SQL commands without proper sanitization or parameterization, making it particularly dangerous for database integrity and confidentiality.
The technical exploitation of this vulnerability allows remote attackers to execute arbitrary SQL commands against the underlying database system. When a user submits a search query through the vulnerable component, the input parameter is concatenated directly into SQL statements without proper input validation or escaping mechanisms. This creates an opportunity for attackers to inject malicious SQL code that can manipulate database contents, extract sensitive information, modify data structures, or even gain unauthorized access to the database server itself. The vulnerability specifically targets the search functionality of the Jobline component, which is commonly used for job posting and search features on Joomla! websites, making it a prime target for attackers seeking to compromise job boards and employment-related websites.
The operational impact of this vulnerability extends beyond simple data theft or manipulation, as it can lead to complete system compromise and unauthorized access to sensitive information. Attackers can leverage this vulnerability to extract user credentials, personal information, job listings, and other confidential data stored within the database. The vulnerability affects Joomla for their web presence, including employment platforms, educational institutions, and corporate websites, the potential for widespread impact is substantial. The vulnerability also demonstrates poor input validation practices and highlights the importance of secure coding methodologies in web application development.
Mitigation strategies for this vulnerability should include immediate patching of the affected Jobline component to version 1.3.2 or later, which contains the necessary security fixes. Organizations should also implement proper input validation and parameterized queries throughout their applications to prevent similar vulnerabilities from occurring in the future. The use of web application firewalls and database access controls can provide additional layers of protection against SQL injection attacks. Security practitioners should follow established frameworks such as the CWE (Common Weakness Enumeration) classification for SQL injection vulnerabilities, which falls under CWE-89, and implement defensive measures aligned with ATT&CK framework techniques for SQL injection prevention. Additionally, regular security audits, code reviews, and vulnerability assessments should be conducted to identify and remediate similar issues across the entire application stack, ensuring comprehensive protection against database-related attack vectors.
