The CVE-2011-1105 vulnerability represents a critical cross-site scripting flaw discovered in Mutare EVM software, a telecommunications system designed for enterprise communication management. This vulnerability affects the security posture of organizations relying on this platform for their communication infrastructure, creating potential entry points for malicious actors seeking to exploit user sessions and access sensitive information. The vulnerability specifically resides in the input validation mechanisms of the system's delivery address and PIN handling components, which fail to properly sanitize user-supplied data before processing or rendering within web interfaces.
The technical exploitation of this vulnerability occurs through the injection of malicious scripts or HTML code into the application's web interface through two primary attack vectors. Attackers can manipulate the delivery address field to inject malicious payloads that execute in the context of other users' browsers when they view or interact with the affected application. The second vector involves the PIN field, which also suffers from insufficient input validation, allowing attackers to inject scripts that can execute within user sessions. These vulnerabilities fall under the CWE-79 category of Cross-Site Scripting, specifically representing reflected XSS attacks where malicious input is immediately reflected back to the user without proper sanitization or encoding.
The operational impact of CVE-2011-1105 extends beyond simple script injection, as it enables attackers to perform session hijacking, steal user credentials, and potentially gain unauthorized access to sensitive communication data. Organizations using Mutare EVM systems may experience compromised user sessions, leading to potential data breaches and unauthorized access to communication channels. The vulnerability particularly affects enterprise environments where communication systems are integral to business operations, as attackers could exploit these flaws to intercept sensitive communications or disrupt critical business processes. The reflected nature of these XSS attacks means that successful exploitation requires user interaction with maliciously crafted links or pages, making social engineering attacks more effective against vulnerable systems.
Mitigation strategies for this vulnerability should focus on implementing comprehensive input validation and output encoding mechanisms throughout the application's web interface. Organizations must ensure that all user-supplied data, particularly in fields handling delivery addresses and PINs, undergoes proper sanitization before being processed or rendered in web contexts. The implementation of Content Security Policy headers can provide additional protection against script injection attacks, while regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components. According to ATT&CK framework category T1059, this vulnerability represents a technique for executing malicious code through web application interfaces, making it particularly relevant for defensive security measures targeting application-layer attacks. System administrators should also consider implementing web application firewalls and monitoring for unusual patterns of data injection attempts that could indicate exploitation attempts against this or similar vulnerabilities.
