CVE-2024-0949: Elektraweb Authentication Bypass Flaw

CVE-2024-0949 Overview

CVE-2024-0949 is a critical authentication bypass vulnerability affecting Talya Informatics Elektraweb. The vulnerability stems from multiple security weaknesses including missing authentication mechanisms, files or directories accessible to external parties, and the use of hard-coded credentials. These combined flaws allow remote attackers to bypass authentication controls without requiring any privileges or user interaction.

Critical Impact

Remote attackers can bypass authentication entirely, potentially gaining unauthorized access to the Elektraweb system with full confidentiality, integrity, and availability impact.

Affected Products

• Talya Informatics Elektraweb versions before v17.0.68

Technical Details for CVE-2024-0949

Vulnerability Analysis

This vulnerability combines three distinct security weaknesses (CWE-306: Missing Authentication for Critical Function) that together create a severe authentication bypass condition. The vulnerability is network-accessible, requiring no special privileges or user interaction to exploit. The attack complexity is low, making exploitation straightforward for attackers with network access to the vulnerable system.

The impact spans all three security domains: confidentiality, integrity, and availability are all highly impacted. An attacker successfully exploiting this vulnerability could gain complete unauthorized access to the Elektraweb system, potentially viewing, modifying, or disrupting sensitive data and operations.

Root Cause

The root cause of CVE-2024-0949 lies in fundamental authentication design flaws within Elektraweb. The system fails to properly authenticate users for critical functions (CWE-306), exposes files or directories to external parties without proper access controls, and utilizes hard-coded credentials that can be discovered and exploited by attackers. These vulnerabilities indicate systemic security design issues in versions prior to v17.0.68.

Attack Vector

The attack vector is network-based, allowing remote exploitation without physical access to the target system. An attacker can exploit this vulnerability by leveraging the missing authentication mechanisms to directly access protected resources. The use of hard-coded credentials provides an additional attack path, as these credentials may be extracted from the application and reused to bypass authentication entirely.

The vulnerability does not require any user interaction or special privileges, making it an attractive target for automated scanning and exploitation attempts. Attackers can potentially access sensitive files and directories that should be protected, leading to data exfiltration or system compromise.

Detection Methods for CVE-2024-0949

Indicators of Compromise

• Unusual authentication attempts or successful logins without corresponding valid user sessions
• Access to protected files or directories from external IP addresses
• Log entries showing bypass of normal authentication workflows
• Network traffic patterns indicating reconnaissance or exploitation attempts against Elektraweb endpoints

Detection Strategies

• Monitor authentication logs for anomalous patterns such as successful authentications without proper credential submission
• Implement network traffic analysis to detect attempts to access protected resources without authentication
• Deploy web application firewall (WAF) rules to detect and block authentication bypass attempts
• Review access logs for requests to sensitive files or directories from unauthorized sources

Monitoring Recommendations

• Enable verbose logging on Elektraweb instances to capture detailed authentication events
• Configure alerting for failed and anomalous authentication patterns
• Monitor for any access attempts using known hard-coded credential patterns
• Implement real-time monitoring of network traffic to Elektraweb systems

How to Mitigate CVE-2024-0949

Immediate Actions Required

• Upgrade Talya Informatics Elektraweb to version v17.0.68 or later immediately
• Restrict network access to Elektraweb systems to trusted IP ranges only
• Implement additional authentication controls such as multi-factor authentication where possible
• Review system logs for any signs of prior exploitation

Patch Information

Talya Informatics has addressed this vulnerability in Elektraweb version v17.0.68. Organizations running affected versions should prioritize upgrading to the patched version. For additional information, refer to the USOM Security Notification TR-24-0808.

Workarounds

• Implement network segmentation to limit exposure of Elektraweb systems to untrusted networks
• Deploy a web application firewall (WAF) with rules to detect and block authentication bypass attempts
• Restrict access to the Elektraweb interface through firewall rules or VPN requirements
• Monitor for unauthorized access attempts while awaiting patch deployment
