Defending from Vulnerabilities: Exploiting Object Injection for Remote Code Execution (RCE)

Object injection occurs when user-supplied input is deserialized into an object within the application without proper validation or sanitization.

Defending from Vulnerabilities: Server-Side Template Injection (SSTI)

Defending from Vulnerabilities: Server-Side Template Injection (SSTI)

SSTI can lead to severe outcomes, including remote code execution (RCE), data theft, and privilege escalation. This scenario underscores the importance of adequately handling user input, especially when using templating engines to generate content dynamically.

Defending from Vulnerabilities: Timing Attack Exploitation via Server-Side Request Forgery (SSRF)

Defending from Vulnerabilities: Timing Attack Exploitation via Server-Side Request Forgery (SSRF)

In this week's series, we delve into a more sophisticated server-side attack—exploiting Server-Side Request Forgery (SSRF) using a timing attack. SSRF vulnerabilities occur when an attacker can manipulate server-side logic to make unauthorized network requests to internal or external services.

Defending from Vulnerabilities: Exploiting Payment Discounts via Logical Flaws

Defending from Vulnerabilities: Exploiting Payment Discounts via Logical Flaws

The attacker manipulates the discount application by applying multiple discount codes, even though the system is supposed to allow only one. This manipulation results in an excessive discount, allowing the attacker to purchase items at a much lower price or even for free.

Defending from Vulnerabilities: Bypassing Payment Validation with Mixed Price Manipulation

Defending from Vulnerabilities: Bypassing Payment Validation with Mixed Price Manipulation

Price manipulation is not always about setting negative amounts or reduced amount which you can prevent by adding a validation. However, often the validation can be bypassed or abused by mixed price manipulations.

Defending from Vulnerabilities: Endless Redirection Loop in URL Parameters

Defending from Vulnerabilities: Endless Redirection Loop in URL Parameters

If the redirections are improperly handled, they often lead to open redirection attacks. However, if the number of redirection attempts is not implemented, it can cause a redirection loop, leading to an application-level denial of service and resource exhaustion attack.

Defending from Vulnerabilities: Persistent XSS via Lack of Internal Application Data Validation

Defending from Vulnerabilities: Persistent XSS via Lack of Internal Application Data Validation

As a developer, you must perform input validation at each stage even if the data is already stored in the application because avoiding this could still lead to a malicious input to trigger on later interaction (second degree), causing issues like cross-site scripting (XSS).

🔌 Cyber Safety Tip of the Week: Avoid Using Public USB Charging Stations! ⚠️📱

Public USB charging stations, often found in airports, hotels, and other public places, might seem convenient, but they can pose serious security risks. Cybercriminals can tamper with these stations to install malware on your device or steal your data in a practice known as "juice jacking."

Defending from Vulnerabilities: Unauthorized File Upload via Undocumented PUT Method

Defending from Vulnerabilities: Bypass in Password Change Functionality

Password changes and updates after authentication are common functionalities found in most applications. While each application implements them differently, it is essential to ensure they are securely implemented.
