Overview
CVE-2025-13872 describes a Blind Server-Side Request Forgery (SSRF) vulnerability found in the survey-import feature of ObjectPlanet Opinio 7.26 rev12562. This vulnerability allows a remote attacker to force the Opinio server to make arbitrary HTTP GET requests to internal or external destinations by crafting malicious import requests. This can lead to sensitive information disclosure, internal network scanning, or even exploitation of other internal services.
Technical Details
The vulnerability resides within the survey import functionality of Opinio. By crafting a specially designed import request, an attacker can inject a URL that the Opinio server will then attempt to access via an HTTP GET request. Because it’s a *blind* SSRF, the attacker does not directly see the response from the target server, making detection and exploitation more challenging but still impactful. The precise vector lies in how Opinio handles the URL provided during the import process, lacking sufficient validation or sanitization of the input. The vulnerable version is ObjectPlanet Opinio 7.26 rev12562 on web-based platforms.
CVSS Analysis
Currently, the CVE entry lists the severity and CVSS score as N/A. However, based on the nature of Blind SSRF vulnerabilities, it’s crucial to assess the potential impact and assign an appropriate score. SSRF vulnerabilities can have a high severity depending on the accessibility of internal resources and the sensitivity of data exposed. Without further information, it’s difficult to provide an exact CVSS score, but administrators should treat this as a high-risk finding until otherwise informed.
Possible Impact
The impact of this Blind SSRF vulnerability can be significant:
- Internal Port Scanning: An attacker could use the Opinio server to scan internal networks, identifying open ports and services.
- Information Disclosure: The server might inadvertently expose sensitive internal resources or configuration files if requested through the SSRF.
- Service Exploitation: If vulnerable internal services are discovered, the attacker could leverage the SSRF to exploit them.
- Denial of Service (DoS): The attacker might target a specific resource causing a denial of service.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-13872, the following steps are recommended:
- Upgrade Opinio: Check the ObjectPlanet website for an updated version of Opinio that addresses this vulnerability. Refer to the changelog for confirmation.
- Input Validation: Implement strict input validation on the survey import feature to prevent malicious URLs from being processed. This includes whitelisting allowed protocols and domains, and sanitizing any user-supplied input.
- Network Segmentation: Segment the Opinio server from sensitive internal resources to limit the potential impact of an SSRF attack.
- Web Application Firewall (WAF): Deploy a WAF to detect and block malicious requests targeting the survey import functionality. Configure rules to identify patterns associated with SSRF attacks.
- Monitor Outbound Traffic: Implement monitoring of outbound HTTP requests originating from the Opinio server to detect any suspicious activity.
