Overview
This article provides a comprehensive analysis of CVE-2025-54560, a Server-Side Request Forgery (SSRF) vulnerability discovered in the Application Server of Desktop Alert PingAlert versions 6.1.0.11 to 6.1.1.2. This vulnerability allows attackers to probe internal infrastructure, potentially leading to sensitive information disclosure and further exploitation.
Technical Details
The SSRF vulnerability exists within the PingAlert Application Server. An attacker can craft malicious requests that force the server to make HTTP requests to arbitrary internal or external resources. This can be achieved by manipulating parameters that control URL construction or request destinations within the PingAlert application. By exploiting this vulnerability, an attacker can:
- Scan internal network ports and services.
- Access internal resources that are not directly accessible from the internet.
- Potentially read sensitive data from internal services (e.g., configuration files, database credentials).
- Bypass firewalls and access control lists (ACLs).
The vulnerable component allows for URL manipulation without proper sanitization or validation. An example exploit scenario might involve crafting a URL within the PingAlert interface that instructs the server to make a request to http://internal.server:8080/admin/config.txt, exposing potentially sensitive configuration information.
CVSS Analysis
While the CVE entry currently lists the Severity and CVSS Score as N/A (Not Available), the potential impact of an SSRF vulnerability should be considered serious. A proper CVSS score would likely be assigned after further investigation. It’s crucial to consider the specific context and potential impact on your organization’s infrastructure when assessing the risk.
Possible Impact
The impact of CVE-2025-54560 could be significant. A successful exploitation could lead to:
- Internal Reconnaissance: Attackers can map the internal network, identify running services, and gather information about system configurations.
- Data Breach: Sensitive data stored on internal systems can be accessed and exfiltrated.
- Privilege Escalation: SSRF can be used to access internal administration interfaces or APIs, potentially leading to privilege escalation.
- Denial of Service (DoS): Attackers can overload internal services by forcing the server to make numerous requests.
Mitigation and Patch Steps
To mitigate the risks associated with CVE-2025-54560, the following steps are recommended:
- Upgrade PingAlert: Upgrade to a patched version of Desktop Alert PingAlert that addresses the SSRF vulnerability. Check Desktop Alert’s official website for the latest updates.
- Input Validation: Implement strict input validation and sanitization on all URL parameters within the PingAlert application. Ensure that URLs are properly validated against a whitelist of allowed destinations.
- Network Segmentation: Implement network segmentation to limit the impact of a successful SSRF attack. Isolate critical internal systems from the PingAlert server.
- Firewall Rules: Configure firewall rules to restrict outgoing traffic from the PingAlert server to only necessary destinations.
- Regular Monitoring: Monitor network traffic and server logs for suspicious activity, such as unusual outbound requests or attempts to access internal resources.
