With the growing scale of cybersecurity threats day by day, digitally installed applications present on open platforms are more vulnerable to risk. To reduce these web application security risks, we will learn specific methods and practices in this blog.
10 Web Application Security Risks
This article discusses 10 common risk factors to web application security.
- SQL injection
- Cross-site scripting (XSS)
- Cross-site request forgery (CSRF)
- Insecure direct object references
- Remote code execution
- Insufficient logging and monitoring
- Insecure cryptographic storage
- Failure to restrict URL access
- Cross-origin resource sharing (CORS) misconfiguration
- Using components with known vulnerabilities
1. SQL injection
An attack involving SQL injection happens when an intruder enters illicit code into an application’s databases via user-provided sections. These sorts of attacks might achieve a variety of objectives. Enabling an attacker to gain entry to private information kept in the database without authorization is one of the two most frequent results.
Login credentials, banking details, and other personal information may be accessible to the attacker, depending on the type of information stored in the database of records. The following result might involve data alteration or erasure. For example, an individual could run the DROP TABLE or DROP DATABASE commands.
Ways to mitigate:
- Verify the customer’s entries.
- Employ output encoding to avoid unique characters like < and > from being rendered as the code for HTML.
- Rather than using dynamic SQL wherever feasible, utilize saved procedures, query parameters, or predefined remarks.
There are suggested methods for managing user data in the majority of languages and platforms. By combining both front- and back-end protocols to avoid SQL injection, the application itself may improve its protection against this sort of risk.

2. Cross-site scripting (XSS)
Cross-site scripting (XSS) attacks include introducing harmful code or scripts into an internet page. The internet page then runs the code, enabling an intruder to obtain private user information such as session credentials and cookies, as well as do additional operations.
There are merely two forms of XSS attacks: reflective and stored. In reflective XSS attacks, attackers inject unwanted scripts into a website, which the site immediately executes. In stored XSS attacks, attackers inject malicious code that the website stores and later executes when triggered.
If effective, a cross-site scripting attack can steal client IDs, damage websites, and lead visitors to hostile websites, allowing for scams.
Ways to mitigate:
- Verify the customer’s data.
- Apply output encrypting methods.
- Utilize automated hygiene tools like OWASP AntiSamy.
- Create an information safety procedure.
3. Cross-site request forgery (CSRF)
In a cross-site request forgery (CSRF) attack, an attacker tricks the target into performing an action on a website without their knowledge. The attacker often inserts a malicious link or page into a site the target is currently browsing. When the target clicks the link or submits a form, the action executes on the attacker’s behalf, potentially causing data loss or unauthorized access.
Ways to mitigate:
- Use CSRF safeguards incorporated into the system you are utilizing, if appropriate.
- Employ CSRF credentials, which are distinctive, random variables associated with the time a user is online, to validate the legitimacy of submissions in applications and URLs.
- Using SameSite cookies, which the browser sends only in response to the specific source that created them.
- This can assist in prohibiting cybercriminals from sending inquiries on behalf of an attacker by denying them permission to the user’s SameSite cookies.

4. Insecure direct object references
Insecure Direct Object References (IDOR) arise when a program discloses immediate object citations, like URLs or database links, allowing hackers to access sensitive information by modifying these identifiers.
Ways to mitigate:
- Implement proper session management and access controls to ensure only authorized users can access specific assets or information.
- In helping prohibit criminals from changing object-specific connections to access-restricted information, verify that input from users is of the appropriate category, width, and structure.
- Rather, look into using globally unique identifiers (GUIDs) to avoid intruders from assuming the specific object addresses required for entering encrypted information.
5. Remote Code Execution
Remote Code Execution vulnerabilities enable criminals to run arbitrary programs on a processor, probably resulting in complete system compromise and unwanted use of private data.
These attacks may take an array of forms, including leveraging weaknesses within software libraries or inserting spyware into user-defined areas.
A competent RCE operation could have produced several outcomes. These involve Denial of Service assaults, the disclosure of confidential data, illegal mining of cryptocurrency, and the installation of a virus. In some instances, an effective operation could enable a hacker to have full authority over the affected system.
Ways to mitigate:
- Clean up user involvement.
- RCE hackers might exploit storage problems like buffer spills.
- Running frequent vulnerability assessments on applications may assist you in uncovering buffer overflows and memory-related flaws that a hacker might abuse.
- Constantly maintain your computer’s OS and third-party programs up-to-date to guarantee you get the most recent safety updates.
- Minimize a hacker’s capacity to travel via a system by using network splitting, authorization, and a lack of confidence safety measure.
6. Insufficient logging and monitoring
Insufficient logging and monitoring refer to the absence of appropriate tracking and surveillance mechanisms established for identifying and reacting to safety concerns.
This allows intruders to go undetected and keep trying to breach the network, which might result in information and monetary damage.
It’s also crucial to understand what is being recorded. If highly confidential data, including card numbers or login details, is uploaded to logs, intruders who acquire access to the logs may exploit such data unlawfully. Illegal Activities, credit card transactions, or illegal access to a system might be readily accomplished.
Ways to mitigate:
- Log critical actions and events in the application and examine logs frequently.
- Use log evaluation techniques to automate log inspection management, enabling faster and more effective identification of potential threats or abnormalities.
- Configure monitoring devices to warn management of any possible security vulnerabilities in immediate detail, permitting employees to jump in faster to imminent attacks.
- Make sure sensitive data is not simply contained in access or is correctly disguised.
7. Insecure cryptographic storage
Insecure cryptographic storage occurs when systems mismanage key cryptography, such as storing keys in a simple form or using weak keys. Vulnerability can provide hackers with entry to private data by compromising encrypted keys.
Ways to mitigate:
- To safeguard saved information, employ powerful cryptographic methods.
- To support breaking the ability to protect data, use secure key management techniques, including changing passwords often and keeping them in a safe place.
- Secured solutions for storage, which include security modules for hardware or protected devices for storage, can assist with safeguarding data that is encrypted.
8. Failure to restrict URL access
Failure to restrict URL access indicates an absence of adequate access oversight, allowing unauthorized individuals to gain entry to restricted pages and services.
This can provide hackers with entry to private information, possibly compromising the system. This type of vulnerability is primarily analogous to and linked to those weaknesses we addressed previously.
The primary distinction permits an intruder to enter information stored in the database. In contrast, failing to limit URL knowledge grants the perpetrator exposure to specific tools and capabilities that no regular consumer should know.
Ways to mitigate:
- Implement adequate access controls by establishing verification and authorization procedures to guarantee that only those with permission have permission to use specific assets or services.
- Implement role-based permission. The authorization system should prohibit any kind of access by default, necessitating specific permissions from specified users and positions for browsing every single page.
- Install suitable approval procedures for the pertinent phases of consumers’ mobile application use.
9. Cross-Origin Resource Sharing
Cross-Origin Resource Sharing is a safety measure that enables a website’s server to control the domains that have access to its assets. However, if CORS is incorrectly configured, hackers can get unauthorized access to limited assets via an alternate source. This might disclose information via applications that can be accessed without consent.
Ways to mitigate:
- Configure CORS headers correctly.
- Employ CORS frameworks that offer a simple interface for setting CORS flags to ensure that CORS is configured correctly.
10. Using components with known vulnerabilities
Utilizing elements having identified weaknesses means using out-of-date software libraries, platforms, or additional components that have known flaws.
Most contemporary internet pages are constructed with complicated parts, making it challenging for engineers to comprehend how they function inside. This can lead to potential weaknesses if the component has identified weaknesses that need to be fixed correctly.
Ways to mitigate:
- Maintain a record of element revisions.
- One may resolve any holes by frequently looking for upgrades and using the most recently released versions of modules.
- Employ antivirus programs to assist you in detecting recognized weaknesses in modules and notify programmers of possible concerns.
