CVE-2010-1865 in ClanSphere
Summary
by MITRE
Multiple SQL injection vulnerabilities in ClanSphere 2009.0.3 and earlier allow remote attackers to execute arbitrary SQL commands via (1) the IP address to the cs_getip function in generate.php in the Captcha module, or (2) the s_email parameter to the cs_sql_select function in the MySQL database driver (mysql.php).

The vulnerability identified as CVE-2010-1865 represents a critical security flaw in ClanSphere 2009.0.3 and earlier versions, specifically targeting SQL injection attack vectors that enable remote code execution. This vulnerability affects the core database interaction mechanisms of the application, creating a pathway for malicious actors to manipulate database queries and potentially gain unauthorized access to sensitive information. The flaw resides in two distinct locations within the application's codebase, each presenting unique attack surfaces that collectively weaken the overall security posture of the system.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the ClanSphere application's database handling functions. The first attack vector targets the cs_getip function in generate.php within the Captcha module, where user-provided IP address data is directly incorporated into SQL queries without proper escaping or parameterization. The second vulnerability occurs in the cs_sql_select function within mysql.php, where the s_email parameter is processed and integrated into database queries without adequate protection against malicious input. Both scenarios demonstrate poor secure coding practices that violate fundamental security principles for database interaction and input handling.
From an operational perspective, this vulnerability poses significant risks to organizations utilizing ClanSphere, as it allows remote attackers to execute arbitrary SQL commands against the underlying database system. Attackers can leverage these injection points to extract sensitive data, modify database contents, or potentially escalate privileges within the system. The impact extends beyond simple data theft, as successful exploitation could lead to complete system compromise, unauthorized access to user accounts, and potential data corruption. The remote nature of the attack means that adversaries do not require physical access to the system, making the vulnerability particularly dangerous in networked environments where the application is exposed to external traffic.
The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws in software applications, and demonstrates characteristics consistent with the ATT&CK framework's credential access and defense evasion techniques. Organizations affected by this vulnerability should prioritize immediate remediation through patching to the latest version of ClanSphere, which contains proper input validation and sanitization mechanisms. Additionally, implementing proper parameterized queries, input validation, and output encoding practices would provide defense in depth against similar vulnerabilities. Network segmentation and monitoring of database access patterns should also be considered as additional mitigations to detect and prevent exploitation attempts.
The broader implications of this vulnerability highlight the importance of regular security assessments and timely patch management in maintaining application security. Legacy applications like ClanSphere 2009.0.3 often contain multiple unpatched vulnerabilities that create persistent security risks, emphasizing the need for organizations to maintain up-to-date software versions and implement comprehensive security monitoring strategies. This vulnerability serves as a reminder of the critical importance of secure coding practices and the potential consequences of inadequate input validation in database-driven applications, particularly those handling user-supplied data through web interfaces.
