Impact: System deadlock leading to potential system compromise or data leakage

Affected Products

Product | Affected Versions

Copyparty | Up to but not including 1.18.9

How the Exploit Works

The vulnerability resides in the filter parameter for the “Recent Uploads” page in versions of Copyparty prior to 1.18.9. This parameter allows arbitrary RegExes. If this feature is enabled (which is the default setting), an attacker can craft a filter introducing a complex enough regular expression that would cause the server to enter into an infinite loop or consume excessive resources, thus deadlocking the server.

Conceptual Example Code

The following pseudocode exemplifies how an attacker might exploit this vulnerability:

GET /recent-uploads?filter=(a+)+b HTTP/1.1
Host: target.example.com

In this example, the filter `(a+)+b` is a classic example of a regular expression that can lead to catastrophic backtracking, causing the server to consume excessive resources and enter a deadlock state.

Mitigation

For mitigation, it’s recommended to upgrade to Copyparty version 1.18.9 or later where this vulnerability has been fixed. As a temporary countermeasure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be configured to block or filter requests containing complex or potentially malicious regular expressions.

Vulnerability Summary

CVE ID: CVE-2025-54581
Severity: High (7.5/10)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: A successful exploit of this vulnerability could cause a denial-of-service attack, potentially compromising the system and causing data leakage.

Affected Products

Product | Affected Versions

vProxy | 2.3.3 and below

How the Exploit Works

The exploit works by an attacker manipulating the HTTP Proxy-Authorization header. This header is user-controlled and untrusted data is extracted from it. The manipulated data is passed to Extension::try_from and eventually flows into parse_ttl_extension, where it is parsed as a TTL (Time-To-Live) value. If the attacker supplies a TTL of zero (e.g. by setting the username as ‘configuredUser-ttl-0’), a division by zero error occurs, leading to a server crash and a subsequent denial-of-service attack.

Conceptual Example Code

Here is a conceptual example of how this vulnerability might be exploited. This could be done through an HTTP request as shown below:

GET / HTTP/1.1
Host: target.vproxy.com
Proxy-Authorization: Basic Y29uZmlndXJlZFVzZXItdHRsLTA=

The Proxy-Authorization header above is a Base64 encoded string of ‘configuredUser-ttl-0’. The server parses this as a TTL value of zero, leading to a division by zero crash, hence causing a denial-of-service.
For mitigation, it is advised to apply the vendor patch or use WAF/IDS as temporary mitigation. The vulnerability has been fixed in vProxy server version 2.4.0.
