CVE-2025-67076: Agora-project Path Traversal Vulnerability

CVE-2025-67076 Overview

CVE-2025-67076 is a directory traversal vulnerability affecting Omnispace Agora Project versions prior to 25.10. This security flaw allows unauthenticated attackers to read arbitrary files on the system by exploiting the misc controller and the ExternalGetFile action. The vulnerability is limited to files with an extension, but still poses a significant risk for information disclosure of sensitive system and configuration files.

Critical Impact

Unauthenticated remote attackers can read sensitive files from the server, potentially exposing credentials, configuration data, and other confidential information without requiring any user interaction.

Affected Products

• Agora-project Agora-project versions before 25.10

Technical Details for CVE-2025-67076

Vulnerability Analysis

This directory traversal vulnerability (CWE-22) exists in the Agora Project's file retrieval functionality. The ExternalGetFile action within the misc controller fails to properly sanitize user-supplied input, allowing attackers to traverse outside the intended directory structure using path manipulation sequences. The vulnerability enables network-based exploitation without authentication, making it particularly dangerous for internet-facing deployments. Successful exploitation results in unauthorized read access to sensitive files, though it does not permit modification or deletion of data.

Root Cause

The root cause of this vulnerability is insufficient input validation in the ExternalGetFile action. The application fails to properly sanitize path traversal sequences (such as ../) in user-supplied file path parameters. This allows attackers to escape the intended file directory and access files located elsewhere on the server's file system. The restriction that only files with extensions can be read provides minimal protection, as most sensitive configuration files, log files, and source code files contain extensions.

Attack Vector

The attack is network-based and can be executed by any unauthenticated remote attacker who can reach the vulnerable Agora Project instance. The attacker crafts a malicious request to the misc controller targeting the ExternalGetFile action with directory traversal sequences embedded in the file path parameter. This allows navigation outside the web root to access sensitive system files. The attack requires no user interaction and can be automated for reconnaissance or data exfiltration purposes.

The vulnerability can be exploited by manipulating file path parameters sent to the ExternalGetFile action. Attackers typically use sequences such as ../ to traverse parent directories and reach sensitive files like configuration files, application source code, or system files that contain extensions.

Detection Methods for CVE-2025-67076

Indicators of Compromise

• HTTP requests to the misc controller containing path traversal sequences (../, ..%2f, %2e%2e/) in URL parameters
• Web server logs showing repeated requests to ExternalGetFile action with unusual file paths
• Access attempts for sensitive files such as configuration files, .env files, or application source code through web requests
• Anomalous outbound data transfers from the web server that could indicate file exfiltration

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block path traversal patterns in HTTP requests
• Implement application-level logging to capture all file access requests through the misc controller
• Configure intrusion detection systems (IDS) to alert on directory traversal attack signatures
• Monitor web server access logs for suspicious patterns targeting file retrieval endpoints

Monitoring Recommendations

• Enable verbose logging on the Agora Project application to track file access requests
• Implement real-time alerting for requests containing path traversal sequences
• Review web server logs regularly for signs of reconnaissance or exploitation attempts
• Deploy endpoint detection and response (EDR) solutions to monitor file system access patterns

How to Mitigate CVE-2025-67076

Immediate Actions Required

• Upgrade Agora Project to version 25.10 or later immediately
• Review web server logs for evidence of prior exploitation attempts
• Restrict network access to the Agora Project instance to trusted IP ranges if possible
• Implement a web application firewall to block path traversal attempts as a defense-in-depth measure

Patch Information

The vulnerability has been addressed in Agora Project version 25.10. Organizations running earlier versions should upgrade immediately. For more information about the Agora Project and available updates, visit the Agora Project website. Additional security advisory details are available from the Helx Blog Security Advisory.

Workarounds

• Deploy a web application firewall (WAF) with rules to block path traversal sequences in incoming requests
• Restrict access to the misc controller or ExternalGetFile action at the web server level until patching is possible
• Implement network segmentation to limit exposure of the vulnerable application to untrusted networks
• Configure file system permissions to minimize the impact of potential file disclosure
