CVE-2006-6030 in E-Calendar Pro
Summary
by MITRE
Multiple SQL injection vulnerabilities in E-Calendar Pro 3.0 allow remote attackers to execute arbitrary SQL commands via the (1) username and (2) passwd (Password) fields in (a) admin/default.asp; or the (3) Event Title, (4) Location, or (5) Description field when making a search engine query in (b) search.asp. NOTE: some of these details are obtained from third party information.

This vulnerability affects E-Calendar Pro 3.0, a web-based calendar application that suffers from multiple SQL injection flaws in its authentication and search functionality. The vulnerability stems from inadequate input validation and sanitization within the application's database interaction layers, allowing malicious actors to inject arbitrary SQL commands through carefully crafted user inputs.
The primary attack vectors involve three distinct input points within the application's interface. The first vector targets the administrative login functionality through the username and password fields in the admin/default.asp page, where unvalidated inputs are directly concatenated into SQL queries without proper parameterization or escaping mechanisms. The second vector operates through the search functionality in search.asp, where attackers can manipulate the Event Title, Location, or Description fields to inject malicious SQL code during search engine queries. These vulnerabilities represent classic SQL injection flaws that enable attackers to bypass authentication, extract sensitive data, modify database contents, or even execute system commands depending on the database backend and privileges.
The technical implementation of these vulnerabilities aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications. The flaw occurs because the application fails to properly sanitize user inputs before incorporating them into database queries, creating opportunities for attackers to manipulate the intended query execution flow. This vulnerability directly maps to attack techniques described in the MITRE ATT&CK framework under T1190 - Exploit Public-Facing Application, where adversaries target web applications to gain unauthorized access to backend databases. The impact extends beyond simple data theft as attackers can potentially escalate privileges, modify calendar entries, or access administrative functions through these injection points.
The operational impact of this vulnerability is significant for organizations using E-Calendar Pro 3.0, as it provides remote attackers with unauthorized access to calendar data and potentially administrative controls. Attackers can exploit these vulnerabilities to retrieve sensitive information stored in the database, including user credentials, calendar events, and personal information. The vulnerability affects both authentication and search functionalities, meaning that even users attempting to search for calendar events could inadvertently trigger SQL injection attacks. Organizations should immediately implement input validation measures, including parameterized queries, proper escaping of special characters, and regular security testing to mitigate these risks. Additionally, network segmentation and web application firewalls can provide additional layers of protection against exploitation attempts targeting these specific input vectors.
