CVE-2007-0874 in Allons_voter
Summary
by MITRE
Allons_voter 1.0 allows remote attackers to bypass authentication and access certain administrative functionality via a direct request for (1) admin_ajouter.php or (2) admin_supprimer.php. NOTE: this could be leveraged to conduct cross-site scripting (XSS) attacks.

The vulnerability described in CVE-2007-0874 affects Allons_voter 1.0, a web application that appears to be a voting or administrative system. This issue represents a critical authentication bypass flaw that allows remote attackers to access administrative functions without proper credentials. The vulnerability specifically targets two administrative endpoints: admin_ajouter.php and admin_supprimer.php, which are likely responsible for adding and deleting administrative elements respectively. The flaw stems from inadequate access control mechanisms that fail to verify user authentication status before granting access to privileged operations.
The technical nature of this vulnerability aligns with CWE-285, which addresses insufficient authorization issues in software systems. When attackers can directly access administrative scripts without proper authentication, they essentially bypass the entire authentication framework of the application. This direct access path creates a fundamental security weakness where the application's access control logic is completely circumvented, allowing unauthorized users to perform administrative actions that should only be available to authenticated administrators. The vulnerability demonstrates poor input validation and access control implementation, as the system fails to properly verify the identity and privileges of users attempting to access sensitive administrative functions.
The operational impact of this vulnerability is severe and multifaceted, extending beyond simple unauthorized access to include potential cross-site scripting attacks as noted in the advisory. An attacker who successfully bypasses authentication can not only modify administrative settings but also potentially inject malicious scripts into the application's response, creating a vector for XSS attacks that could compromise user sessions or redirect victims to malicious sites. This combination of authentication bypass and XSS potential creates a particularly dangerous exploit scenario where attackers can establish persistent access to the administrative interface while simultaneously creating opportunities for broader client-side attacks. The vulnerability affects the integrity and confidentiality of the entire system, as administrative functions typically control critical data and system configurations.
The attack surface for this vulnerability is particularly concerning given its remote nature, meaning attackers can exploit it from anywhere on the internet without requiring physical access or local network presence. This characteristic makes the vulnerability highly attractive to automated exploitation tools and increases the potential for widespread compromise. From an ATT&CK framework perspective, this vulnerability maps to T1078 Valid Accounts and T1213 Data from Information Repositories, as attackers can leverage the bypassed administrative access to gain persistent access and extract sensitive data. The vulnerability also relates to T1566 Phishing and T1190 Exploitation for Client Execution when considering the XSS component, as attackers can use the administrative access to deploy malicious scripts that target end users. Organizations should implement immediate mitigations including proper access controls, input validation, and authentication verification mechanisms, while also considering network segmentation and monitoring for unauthorized access attempts to administrative functions.
