AMD TEE | All versions prior to vendor patch

How the Exploit Works

In the case of CVE-2021-26383, an attacker who has gained access to a local userspace can exploit the vulnerability by invoking a command with malformed arguments. The insufficient bounds checking in the AMD TEE allows these malformed arguments to access memory out of the allocated bounds. This results in an illegal memory access which can lead to unpredictable system behavior, potentially allowing the attacker to compromise the system or leak data.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. Note, this is a simplified representation and actual exploit code may be more complex:

# Attacker has access to the local userspace
$ ./exploit-program --malformed-argument

In this example, it’s assumed that the attacker has already compromised the userspace and is able to execute arbitrary commands. The `exploit-program` represents any program running in the AMD TEE, and `–malformed-argument` is an argument that can cause out-of-bounds memory access due to insufficient bounds checking.

Mitigation Guidance

The primary mitigation for this vulnerability is to apply the vendor patch provided by AMD. This patch corrects the bounds checking issue, preventing the potential for out-of-bounds memory access.
If immediate patching is not possible, a temporary mitigation can be implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS). These security measures can help detect and block attempts to exploit this vulnerability. However, they should be considered a temporary solution until the vendor patch can be applied.
Please note, the effectiveness of WAFs and IDSs as a mitigation for this vulnerability depends on accurately identifying and blocking exploit attempts, which might not always be possible. Therefore, applying the vendor patch remains the most reliable solution.

Overview

A significant cybersecurity vulnerability, CVE-2025-58437, has been detected in the platform Coder, which is widely used by organizations to provision remote development environments via Terraform. The vulnerability exists in versions 2.22.0 through 2.24.3, 2.25.0 and 2.25.1 of the software. This flaw exposes systems to potential compromise and data leakage, thereby posing a serious threat to the security of users and organizations. Given the extent of Coder’s usage, this vulnerability is of substantial concern and demands immediate attention.

Vulnerability Summary

CVE ID: CVE-2025-58437
Severity: Critical, CVSS score 8.1
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Coder | 2.22.0 – 2.24.3
Coder | 2.25.0 – 2.25.1

How the Exploit Works

The vulnerability arises from insecure session handling in Coder’s prebuilt workspaces. When a workspace is started, Coder generates a session token for the user, which is exposed via coder_workspace_owner.session_token. Prebuilt workspaces, owned by a built-in prebuilds system user, can be claimed by a different user. However, when a workspace is claimed, the previous session token for the prebuilds user is not expired, making it an exploitable vulnerability. Any Coder workspace templates that persist this automatically generated session token are potentially impacted.

Conceptual Example Code

Let’s illustrate this with a conceptual example. Suppose an attacker has somehow gained access to the prebuilds user’s session token. The attacker could then use this token in the following way:

GET /coder_workspace/ HTTP/1.1
Host: vulnerable-coder.com
Authorization: Bearer {prebuilds-user-session-token}
{ "workspace_id": "..." }

In this example, the attacker uses the prebuilds user’s session token to gain unauthorized access to the workspace data. This could potentially lead to data leakage or a system compromise.
Please remember, this is a conceptual example and not an actual exploit.

Mitigation

The vulnerability is fixed in versions 2.24.4 and 2.25.2 of Coder. Therefore, users are strongly recommended to update their software to these versions immediately. As a temporary mitigation measure, users can apply a vendor patch or use Web Application Firewall (WAF) and Intrusion Detection Systems (IDS). Still, the most secure solution is to update to the patched versions of the software.

Affected Products

Product | Affected Versions

ERP | < 14.89.2 ERP | 15.0.0 through 15.75.1 How the Exploit Works

The CVE-2025-58439 vulnerability stems from the ERP tool’s lack of parameter validation in some of its endpoints. This shortcoming allows attackers to send specially crafted requests with malicious SQL commands. These commands can manipulate the database to retrieve sensitive information, such as software version details. In a worst-case scenario, this vulnerability can lead to system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how an attacker might exploit this vulnerability using a malicious SQL command in a POST request:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "'; SELECT VERSION(); -- " }

In this example, the attacker is injecting a SQL command (`SELECT VERSION()`) into the request. The semicolon (`;`) marks the end of one command and the start of another, and the two hyphens (`–`) indicate a comment, causing the database management system to ignore the rest of the malicious payload.

Mitigation Guidance

Users of vulnerable versions of ERP are strongly advised to update their software to version 14.89.2 or 15.76.0, in which this issue has been fixed. If immediate software update is not possible, users can temporarily mitigate the threat by using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to block malicious requests. However, these are only temporary measures, and the ultimate solution is to update the software to a non-vulnerable version.

Overview

The cybersecurity world is abuzz with the discovery of a new vulnerability in WeiPHP v5.0 and before, tagged as CVE-2025-55849. WeiPHP is a popular open-source framework used by programmers to build applications. However, this vulnerability may allow an attacker to manipulate SQL queries, leading to unauthorized access to sensitive data, and potential system compromise. Given the widespread use of WeiPHP, the impact of this vulnerability is potentially far-reaching, affecting numerous applications and by extension, organizations and their users.

Vulnerability Summary

CVE ID: CVE-2025-55849
Severity: High (CVSS:8.4)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Unauthorized access to sensitive data, potential system compromise

Affected Products

Product | Affected Versions

WeiPHP | v5.0 and before

How the Exploit Works

The vulnerability stems from insufficient sanitization of user-supplied inputs in the ‘SucaiController.class.php’ file. An attacker can exploit this by injecting malicious SQL code into the application’s query string. This results in the application unknowingly running the malicious SQL query, which can lead to unauthorized access to sensitive data, modification of data, or even system compromise.

Conceptual Example Code

Here’s a conceptual example of how an attacker might exploit the vulnerability. Suppose the application accepts a parameter ‘template_id’ in the URL to fetch some data:

GET /SucaiController.class.php?template_id=100 HTTP/1.1
Host: vulnerable.example.com

An attacker could substitute ‘100’ with a crafted SQL statement:

GET /SucaiController.class.php?template_id=100;DROP%20TABLE%20users; HTTP/1.1
Host: vulnerable.example.com

This could lead to the ‘users’ table being dropped from the database if the application directly includes the ‘template_id’ parameter in a SQL query without sanitizing it first.

Mitigation Steps

To mitigate this vulnerability, users are advised to apply the patch provided by the vendor as soon as it’s available. In the interim, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used to detect and block SQL Injection attacks. Additionally, developers should always sanitize user inputs before including them in SQL queries to prevent such injection attacks.

Overview

The recent discovery of a significant vulnerability in Envasadora H2O Eireli – Soda Cristal v40.20.4 has raised serious cybersecurity concerns. This flaw, designated as CVE-2025-52389, exposes users to potential system compromise and data leakage. As an Insecure Direct Object Reference (IDOR) vulnerability, it allows authenticated attackers to manipulate HTTP requests to gain unauthorized access to sensitive data.

Vulnerability Summary

CVE ID: CVE-2025-52389
Severity: High, with a CVSS score of 8.8
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
Impact: Unauthorized access to sensitive data, potential system compromise

Affected Products

Product | Affected Versions

Envasadora H2O Eireli – Soda Cristal | v40.20.4

How the Exploit Works

The exploit takes advantage of an IDOR vulnerability. In this scenario, an attacker with authenticated access can manipulate the parameters of an HTTP request to reference objects (data files, user accounts, etc.) that they should not have access to. The system fails to properly verify the user’s authorization before processing the request, thus granting the attacker access to sensitive data.

Conceptual Example Code

Here’s a hypothetical example of how an HTTP request might be crafted to exploit this vulnerability:

GET /user_data?id=12345 HTTP/1.1
Host: vulnerable-website.com
Authorization: Bearer <attacker's legitimate token>
{ "user_id": "67890" }

In this example, the attacker is using their valid session token but changes the ‘user_id’ in the request to that of another user. The server mistakenly trusts the session token and returns sensitive data for user 67890, despite the request coming from the attacker.

Mitigation and Prevention

The best course of action is to apply the vendor’s patch as soon as possible. In the meantime, or if patching is not immediately feasible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These can be configured to detect and block suspicious HTTP requests that may be attempting to exploit this vulnerability. Furthermore, developers should enforce strict access controls and ensure proper authorization checks are in place to prevent such vulnerabilities.

Overview

Critical security vulnerabilities are an ongoing issue for web-based applications, and WordPress themes are no exception. This blog post will delve into the specifics of the CVE-2025-9114 vulnerability discovered in the Doccure theme for WordPress. This vulnerability leaves websites using this theme exposed to potential system compromise or data leakage. It is of particular concern because it allows unauthenticated attackers to bypass authorization, change user passwords, and potentially take over administrator accounts.

Vulnerability Summary

CVE ID: CVE-2025-9114
Severity: Critical (9.8 CVSS Severity Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

Doccure WordPress Theme | Up to and including 1.4.8

How the Exploit Works

The vulnerability stems from the Doccure theme providing user-controlled access to system objects. This effectively allows a user to bypass authorization protocols that are meant to prevent unauthorized system access. Specifically, an unauthenticated attacker can take advantage of this vulnerability to change user passwords, even those of administrator accounts. This ability to alter passwords could potentially allow the attacker to take over these accounts, leading to a full system compromise.

Conceptual Example Code

Consider the example of an unauthenticated HTTP POST request to an endpoint responsible for password changes. By crafting a malicious JSON payload, an attacker could potentially change a user’s password:

POST /password/change HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"username": "admin",
"new_password": "malicious_password"
}

In this conceptual example, the attacker targets the “admin” account and sets a new password (“malicious_password”), effectively taking over the admin account.

Recommended Mitigation

The best mitigation for this vulnerability is to apply the vendor patch as soon as possible. If an immediate patch cannot be applied, temporary mitigation can be achieved by implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block malicious traffic attempting to exploit this vulnerability. It is highly recommended to take action immediately to prevent potential system compromise or data leakage.
