CVE-2011-1104 in EVM
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in Mutare EVM allow remote attackers to hijack the authentication of arbitrary users for requests that (1) change a PIN, (2) delete messages, (3) add a delivery address, or (4) change a delivery address.

The CVE-2011-1104 vulnerability represents a critical cross-site request forgery flaw discovered in Mutare EVM software, a telecommunications system used for managing communication services. This vulnerability exists within the authentication and authorization mechanisms of the system, creating a pathway for malicious actors to exploit user sessions without proper authorization. The flaw specifically affects the web-based administrative interface of the Mutare EVM platform, where users can perform sensitive operations through HTTP requests that are not properly validated for authenticity. The vulnerability stems from the absence of proper anti-CSRF token validation, allowing attackers to craft malicious requests that appear to originate from authenticated users within the system.
The technical implementation of this vulnerability exploits the fundamental weakness in the web application's session management and request validation processes. Attackers can construct specially crafted web pages or send malicious links that, when visited by an authenticated user, automatically submit requests to the Mutare EVM system. These requests target four specific functions that modify critical system parameters including PIN changes, message deletion, and address management operations. The vulnerability operates under the common weakness pattern identified as CWE-352, which describes Cross-Site Request Forgery flaws where applications fail to validate that requests originate from legitimate sources. The attack vector leverages the browser's automatic handling of cookies and session information, where the system automatically authenticates requests based on existing session tokens without verifying the user's intent.
The operational impact of this vulnerability extends beyond simple data modification, as it allows attackers to completely compromise user accounts and system integrity. When an authenticated user visits a malicious page, the CSRF attack can silently perform actions such as changing PINs which would grant the attacker full administrative access to the system, deleting important messages that could contain critical information, or modifying delivery addresses to redirect communications. This creates a significant risk for organizations relying on Mutare EVM for telecommunications management, as the compromise of a single user session could lead to complete system takeover. The vulnerability affects the confidentiality, integrity, and availability of the communication system, potentially enabling data exfiltration, service disruption, and unauthorized access to sensitive telecommunications infrastructure. According to the MITRE ATT&CK framework, this vulnerability maps to techniques involving credential access and privilege escalation through session management flaws.
Mitigation strategies for CVE-2011-1104 should focus on implementing robust anti-CSRF protection mechanisms within the Mutare EVM system. The primary solution involves implementing anti-CSRF tokens that are generated per session and validated for each request, ensuring that requests originate from legitimate user interactions rather than automated malicious submissions. Organizations should also implement proper request validation that checks referer headers and origin domains to prevent unauthorized requests from external sources. Additionally, the system should enforce strict session management practices including session timeout mechanisms and secure cookie attributes to prevent session hijacking. Regular security assessments and input validation should be implemented to identify similar vulnerabilities in other system components. The remediation process should include immediate patching of the affected Mutare EVM software version and implementation of comprehensive security monitoring to detect potential exploitation attempts. Organizations should also establish incident response procedures specifically designed to handle session-based attacks and maintain detailed audit logs of all administrative actions for forensic analysis purposes.
