The CVE-2010-4935 vulnerability represents a critical sql injection flaw in the enTrans 0.3.2 content management system and earlier versions. This vulnerability specifically affects the poll.php script which processes user input through the sid parameter without adequate sanitization or validation. The flaw enables remote attackers to inject malicious sql commands directly into the application's database layer, potentially compromising the entire system. The vulnerability exists due to insufficient input validation mechanisms that fail to properly escape or filter user-supplied data before incorporating it into sql queries.
This sql injection vulnerability falls under the common weakness enumeration CWE-89 which categorizes sql injection as a serious security flaw that allows attackers to manipulate database queries. The attack vector is particularly dangerous because it operates over remote network connections without requiring authentication, making it highly exploitable in automated attack scenarios. The sid parameter serves as the primary injection point where malicious input can be crafted to bypass normal query execution and instead execute unauthorized database operations. This type of vulnerability is classified under the attack technique T1190 in the ATT&CK framework as it represents a method for executing arbitrary code through database manipulation.
The operational impact of this vulnerability extends beyond simple data theft to include complete system compromise. Attackers can leverage this flaw to extract sensitive information such as user credentials, personal data, and system configurations from the underlying database. The vulnerability also enables attackers to modify or delete database records, potentially causing data integrity issues and service disruption. Additionally, successful exploitation can lead to privilege escalation within the database environment, allowing attackers to gain elevated access rights and potentially move laterally within the network infrastructure. The vulnerability affects all versions of enTrans up to and including 0.3.2, making it a widespread concern for organizations running outdated software systems.
Mitigation strategies for CVE-2010-4935 must address both immediate remediation and long-term security improvements. The most effective immediate solution involves upgrading to a patched version of enTrans beyond 0.3.2 where the sql injection vulnerability has been resolved through proper input validation and parameterized query implementation. Organizations should implement proper input sanitization techniques including the use of prepared statements and parameterized queries to prevent sql injection attacks. Network segmentation and database access controls should be strengthened to limit the potential impact of successful exploitation attempts. Regular security audits and vulnerability assessments should be conducted to identify similar flaws in other applications and systems. The implementation of web application firewalls and intrusion detection systems can provide additional layers of protection against sql injection attempts targeting this and similar vulnerabilities.
