Overview
A critical security vulnerability, tagged as CVE-2025-54122, has been identified in the Manager-io/Manager accounting software. This vulnerability, an unauthenticated full read Server-Side Request Forgery (SSRF), affects both the Desktop and Server editions of the software. It allows attackers to bypass network isolation and access restrictions, potentially gaining access to internal services, cloud metadata endpoints, and facilitating the exfiltration of sensitive data from isolated network segments. This vulnerability is of significant concern to all users of Manager-io/Manager version up to and including 25.7.18.2519 due to its potential for system compromise or data leakage.

How the Exploit Works
The vulnerability stems from an issue in the proxy handler component of Manager-io/Manager. A malicious actor can send a carefully crafted request to the server, leveraging the SSRF vulnerability to bypass network isolation measures. This allows the attacker to make requests to internal services or cloud metadata endpoints under the guise of the vulnerable server, potentially gaining unauthorized access to sensitive data or system resources.
Conceptual Example Code
Below is a hypothetical HTTP request that an attacker might use to exploit this vulnerability:
GET /proxy?target=http://internal-service.example.com/ HTTP/1.1
Host: vulnerable-manager.example.comIn this example, the attacker is using the vulnerable proxy handler to send a GET request to an internal service that would otherwise be inaccessible. The server processes the request as if it were legitimate, potentially giving the attacker access to sensitive data or system resources.
Mitigation
It is strongly recommended to apply the vendor patch as soon as possible. The vulnerability is fixed in Manager-io/Manager version 25.7.21.2525. As a temporary mitigation, users may also implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block malicious requests attempting to exploit this vulnerability.
