Overview
The CVE-2025-52562 is a severe security flaw found in Performave Convoy, a widely used KVM server management panel by hosting businesses. The vulnerability lies in the LocaleController component of the software. Specifically, it allows an unauthenticated remote attacker to exploit a directory traversal vulnerability, potentially leading to system compromise and data leakage. As the exploit does not require user interaction, it presents a substantial risk to businesses relying on Performave Convoy for their operations.

How the Exploit Works
The directory traversal vulnerability is present in the LocaleController component of Performave Convoy. An attacker can craft a malicious HTTP request with specific locale and namespace parameters, thereby exploiting the directory traversal vulnerability. Thus, the attacker can include and execute arbitrary PHP files on the server, potentially leading to system compromise and data leakage.
Conceptual Example Code
For illustration, a conceptual example of a malicious HTTP request exploiting this vulnerability might look like this:
GET /localeController?locale=../../../../malicious.php&namespace= HTTP/1.1
Host: vulnerable-server.comIn the above example, the attacker is using the `locale` parameter in the HTTP request to traverse the directory structure (‘../../../../’) and execute a malicious PHP file (‘malicious.php’) on the server. This is a conceptual representation and might differ in real-world scenarios based on the server’s specific configurations and setup.
Recommendations for Mitigation
The vulnerability has been patched in Performave Convoy version 4.4.1. Therefore, users are strongly advised to update to this version or later to mitigate the risk. If immediate update is not possible, implementing strict Web Application Firewall (WAF) rules to filter incoming requests targeting the vulnerable endpoints can serve as a temporary workaround. Intrusion Detection Systems (IDS) can also be used to monitor and alert on potential exploitation attempts.
