CVE-2013-7385 in LiveZilla
Summary
by MITRE
LiveZilla 5.1.2.1 and earlier includes the MD5 hash of the operator password in plaintext in Javascript code that is generated by lz/mobile/chat.php, which allows remote attackers to obtain sensitive information and gain privileges by accessing the loginName and loginPassword variables using an independent cross-site scripting (XSS) attack. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7033.

The vulnerability described in CVE-2013-7385 represents a critical security flaw in LiveZilla versions 5.1.2.1 and earlier, specifically within the mobile chat functionality. This issue stems from improper handling of authentication credentials in client-side JavaScript code, creating a significant exposure that could be exploited by remote attackers. The vulnerability manifests through the inclusion of MD5 hashed passwords in plaintext JavaScript code generated by the lz/mobile/chat.php script, fundamentally undermining the security of the authentication mechanism.
The technical implementation of this vulnerability involves the generation of JavaScript code that contains both loginName and loginPassword variables in plaintext format. When an attacker successfully executes a cross-site scripting attack against the vulnerable system, they can directly access these variables and extract the MD5 hashes of operator passwords. This represents a serious deviation from secure coding practices and violates fundamental principles of credential protection. The vulnerability is particularly concerning because it occurs in the mobile chat interface, which typically serves as a critical communication channel for support staff and administrators. The MD5 hash exposure creates a pathway for attackers to potentially reverse-engineer passwords or use the hashes in subsequent attacks, including credential stuffing or brute force attempts against the MD5 algorithm.
The operational impact of this vulnerability extends beyond simple information disclosure, as it enables privilege escalation and unauthorized access to administrative functions. Attackers who successfully exploit this vulnerability can gain access to operator accounts, potentially leading to complete system compromise. This threat is exacerbated by the fact that the vulnerability results from an incomplete fix for CVE-2013-7033, indicating a pattern of inadequate security remediation and suggesting that the vendor may have failed to properly address the underlying architectural issues. The presence of hardcoded credentials in client-side code violates multiple security standards including those outlined in the OWASP Top Ten, specifically addressing insecure authentication mechanisms and sensitive data exposure. Organizations relying on LiveZilla for customer support operations face significant risk of unauthorized access to their support systems, potentially leading to data breaches, service disruption, and reputational damage.
The remediation approach for this vulnerability requires immediate patching of the LiveZilla software to version 5.1.3 or later, which contains the proper fix for both CVE-2013-7385 and CVE-2013-7033. Security administrators should also implement comprehensive monitoring for cross-site scripting attempts and ensure that all mobile chat interfaces are properly secured. Additional mitigations include implementing strict content security policies to prevent unauthorized script execution, conducting regular security audits of client-side code, and ensuring that authentication credentials are never exposed in plaintext within browser contexts. This vulnerability aligns with ATT&CK technique T1566 for initial access through social engineering and T1548 for privilege escalation, demonstrating how credential exposure can enable broader attack vectors. Organizations should also consider implementing multi-factor authentication for operator accounts and regularly reviewing their security configurations to prevent similar issues in other components of their support infrastructure.
