CVE-2007-1050 in MyCalendar
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in index.php in AbleDesign MyCalendar allow remote attackers to inject arbitrary web script or HTML via (1) the go parameter, (2) the keyword parameter in the search menu (go=search), or (3) the username or (4) the password in a go=Login action.

The vulnerability identified as CVE-2007-1050 represents a critical cross-site scripting flaw within the AbleDesign MyCalendar application's index.php file. This vulnerability exposes the system to remote code execution through malicious web script injection, creating significant security risks for users interacting with the calendar application. The flaw specifically affects the application's handling of user input parameters, making it susceptible to persistent and reflected XSS attacks that can compromise user sessions and data integrity.
The technical implementation of this vulnerability occurs through four distinct attack vectors that all originate from the index.php file's parameter processing mechanisms. The first vector involves the go parameter which when manipulated allows attackers to inject malicious scripts directly into the application's response handling. The second vector targets the keyword parameter within the search menu functionality, specifically when the go=search action is invoked, creating a pathway for attackers to inject script code through search queries. The third and fourth vectors exploit the username and password parameters during login operations when the go=Login action is executed, allowing attackers to inject malicious content into authentication forms that can persist across sessions.
From an operational impact perspective, this vulnerability creates substantial risk for organizations utilizing AbleDesign MyCalendar applications. Attackers can exploit these XSS flaws to steal user credentials, hijack sessions, redirect users to malicious sites, or inject malicious content that persists in the calendar application's interface. The vulnerability's impact extends beyond simple script injection as it can enable more sophisticated attacks including session fixation, credential theft, and data exfiltration. The persistent nature of some of these XSS vectors means that malicious content can remain active long after initial exploitation, continuously affecting users who interact with the vulnerable application.
Security professionals should note that this vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications. The attack surface is further defined by ATT&CK technique T1531 which covers the use of malicious inputs to manipulate web application behavior. Organizations should implement comprehensive input validation and output encoding mechanisms to address this vulnerability. The recommended mitigation strategies include implementing strict parameter validation for all user inputs, employing context-specific output encoding, and deploying web application firewalls to detect and prevent malicious script injection attempts. Additionally, regular security audits and code reviews should be conducted to identify similar vulnerabilities in other application components and ensure proper sanitization of all user-supplied data before processing or display within the application interface.
