CVE-2005-1498 in myBloggie
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in myBloggie 2.1.1 allow remote attackers to inject arbitrary web script or HTML via the (1) year parameter in viewmode.php, or the (2) cat_id, (3) month_no, or (4) post_id parameter in index.php, which are not properly sanitized before they are displayed in an error message. NOTE: issues 2, 3, and 4 may be due to a problem in associated products rather than myBloggie itself.

The vulnerability described in CVE-2005-1498 represents a critical cross-site scripting flaw affecting myBloggie version 2.1.1, a web-based blogging platform that was prevalent during the mid-2000s era of content management systems. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is classified as one of the most common and dangerous web application security flaws according to the CWE database maintained by the MITRE Corporation. The vulnerability specifically manifests in two distinct attack vectors within the application's error handling mechanisms, where user-supplied input parameters are not properly sanitized before being rendered back to users in error messages.
The technical implementation of this vulnerability occurs through multiple parameter injection points within the application's PHP scripts. The primary attack vector involves the year parameter in viewmode.php, while secondary vectors target cat_id, month_no, and post_id parameters in index.php. These parameters are typically used for navigation and filtering purposes within the blogging interface but become dangerous when they are not properly validated or sanitized. When an attacker crafts malicious input containing script tags or other HTML content and submits it through these parameters, the application fails to properly escape or filter the input before displaying it in error messages, creating a persistent XSS vulnerability.
The operational impact of this vulnerability is significant as it allows remote attackers to execute arbitrary web scripts or HTML content within the context of any user's browser session. This means that when a victim visits a page containing maliciously crafted parameters, the injected scripts could perform actions such as stealing session cookies, redirecting users to malicious websites, defacing the blog content, or even executing commands on the victim's machine if the browser's security settings are inadequate. The vulnerability affects the entire user base of the affected myBloggie installation, making it particularly dangerous for blogs with substantial traffic or those used by organizations where users might have administrative privileges.
The root cause of this vulnerability lies in the application's failure to implement proper input validation and output encoding practices, which are fundamental security measures recommended by the Open Web Application Security Project (OWASP) and the Center for Internet Security (CIS). This particular flaw demonstrates the importance of the principle of least privilege in web application security, where all user inputs should be treated as potentially malicious and properly sanitized before any processing or display occurs. The fact that the vulnerability may extend to associated products rather than being solely contained within myBloggie itself suggests a broader architectural issue in how the application handles error reporting and user input processing. This type of vulnerability would typically be classified under the ATT&CK technique T1059.001 for Command and Scripting Interpreter, specifically focusing on the execution of malicious scripts through web interfaces, and could potentially enable more advanced attacks such as credential theft or privilege escalation if the vulnerable blog system had administrative access to sensitive resources. Organizations should implement comprehensive input validation mechanisms, output encoding, and regular security audits to prevent such vulnerabilities from being exploited in modern web applications.
