CVE-2006-5086 in Pixel Motion Blog
Summary
by MITRE
Blog Pixel Motion 2.1.1 allows remote attackers to change the username and password for the admin user via a direct request to insere_base.php with modified (1) login and (2) pass parameters. NOTE: this issue was claimed to be SQL injection by the original researcher, but it is not.

The vulnerability identified as CVE-2006-5086 affects Blog Pixel Motion version 2.1.1, a content management system that was prevalent in the mid-2000s web application landscape. This security flaw resides in the application's administrative interface handling mechanism, specifically within the insere_base.php script that manages user authentication and authorization processes. The vulnerability represents a critical authorization bypass issue that allows unauthenticated remote attackers to escalate their privileges by directly manipulating administrative parameters within the application's request structure.
The technical exploitation of this vulnerability occurs through a straightforward yet dangerous method involving direct HTTP requests to the insere_base.php endpoint. Attackers can modify two specific parameters within the request payload: login and pass, which correspond to the username and password fields respectively. This manipulation enables unauthorized individuals to change the administrative credentials without proper authentication, effectively granting them complete control over the affected blog system. The flaw does not constitute a traditional SQL injection vulnerability as initially reported by some researchers, but rather represents a clear case of improper input validation and authentication handling.
From an operational perspective, this vulnerability poses severe risks to organizations relying on Blog Pixel Motion 2.1.1 for their web presence. The remote attack vector means that malicious actors can exploit this weakness from anywhere on the internet without requiring physical access or prior authentication to the system. Once successfully exploited, attackers gain administrative privileges that allow them to modify content, delete posts, install malicious software, manipulate user accounts, and potentially use the compromised system as a launching point for further attacks within the network infrastructure. The impact extends beyond immediate data compromise to include potential service disruption and reputational damage.
Security practitioners should recognize this vulnerability as aligning with CWE-285, which addresses improper authorization issues in software applications. The flaw demonstrates poor access control implementation where the application fails to validate that incoming requests originate from legitimate administrative users with proper credentials. Additionally, this vulnerability can be mapped to ATT&CK technique T1078 which covers valid accounts usage and privilege escalation through unauthorized access to administrative interfaces. Organizations should implement immediate mitigations including updating to patched versions of Blog Pixel Motion, implementing proper input validation controls, restricting direct access to administrative endpoints, and deploying web application firewalls to monitor and block suspicious parameter manipulation attempts. The vulnerability also highlights the importance of regular security assessments and the need for proper authentication mechanisms that do not rely on simple parameter manipulation for critical system functions.
