Overview
CVE-2025-13879 describes a directory traversal vulnerability found in SOLIDserver IP Address Management (IPAM) version 8.2.3. This flaw allows an authenticated user with administrator privileges to access and list directories outside of their authorized scope. By manipulating the ‘directory’ parameter in the /mod/ajax.php?action=sections/list/list endpoint, malicious actors can potentially view sensitive system files and directories, leading to information disclosure and potentially further compromise.
Technical Details
The vulnerability exists within the /mod/ajax.php script, specifically when handling the sections/list/list action. The application fails to properly sanitize or validate the ‘directory’ parameter, allowing an attacker to inject directory traversal sequences (e.g., ../) to navigate outside the intended LOCAL:/// folder. By setting the ‘directory’ parameter to values such as /, an attacker can list the contents of the root directory and other sensitive areas of the server’s file system.
Affected Endpoint: /mod/ajax.php?action=sections/list/list
Vulnerable Parameter: directory
CVSS Analysis
As of the publication date of this blog post, the National Vulnerability Database (NVD) has not assigned a CVSS score to CVE-2025-13879. This means that further analysis is required to understand it’s potential severity. However, the lack of a CVSS score does not mean it’s not dangerous. Directory traversal vulnerabilities can lead to sensitive information disclosure and further exploitation.
Possible Impact
Successful exploitation of this directory traversal vulnerability can have significant consequences, including:
- Information Disclosure: Attackers can access sensitive configuration files, user credentials, and other confidential data stored on the server.
- Privilege Escalation: Gaining access to system files might allow attackers to discover further vulnerabilities and potentially escalate their privileges.
- System Compromise: In some scenarios, attackers could potentially modify or execute arbitrary code on the server, leading to complete system compromise.
- Data Breaches: Sensitive data related to the IPAM system and the network it manages could be exposed, leading to data breaches.
Mitigation or Patch Steps
To mitigate the risk associated with CVE-2025-13879, it is crucial to take the following steps:
- Upgrade SOLIDserver IPAM: Check EfficientIP’s website and resources for a patched version of SOLIDserver IPAM that addresses this vulnerability. Upgrade to the latest stable version as soon as possible.
- Input Validation: Implement robust input validation and sanitization on the ‘directory’ parameter to prevent directory traversal attempts. Ensure that only authorized directories can be accessed.
- Principle of Least Privilege: Review user access controls and ensure that administrators only have the minimum necessary privileges to perform their duties.
- Web Application Firewall (WAF): Deploy a web application firewall (WAF) to detect and block malicious requests targeting the vulnerable endpoint. Configure the WAF with rules to prevent directory traversal attacks.
- Monitor System Logs: Monitor system logs for suspicious activity, such as unusual file access attempts or directory traversal patterns.
