A08:2021 OWASP – Software and Data Integrity Failures

Humans in today’s digital world are surrounded by software and applications. For almost all of your day-to-day personal and professional work, we have an application or software to assist us. However, they are not as useful as they seem. 

If not guarded by enough API security measures, the application/software we use acts as a means for a hacker to reach you. That explains why a cyber-attack is taking place every 39 seconds. 

OWASP Top 10, a well-recognized entity educating people about the problem-causing threat, recently updated the list. A08:2021, the latest vulnerability in OWASP’s most-recent list, is something any software user should be familiar with. Let’s learn more about it.

Learning Objectives

Vulnerability Description

A08:2021 is the new entrant and talks about the seen/unseen dangers that modern-era software/applications bring with them.

Often called as Software and Data Integrity Failures OWASP, it talks about the assumptions linked with critical CI/CD pipeline, data handling, and software update integrity failure. In layman's language, when one uses software/application/critical data without adhering to best verification or authentication practices, multiple threats approaches and A08:2021 covers all of them.

Not going through with the authentication process creates an opportunity for hackers/threat actors to gain authorized access to restricted applications/software. Once that happens, they are allowed to cause endless havoc such as malicious code injection, data theft, and controlling the application/software operation.

Examples of Attacks

Some common examples of A08:2021 are:

  • When end-user updates happen devoid of signing

Many applications/software come with auto-update features and don’t comply with the user-verification process using the digital signing mechanism. Such unsigned update incidences provide an opportunity for threat actors to corrupt the targeted system/software. This could be a serious issue and has no direct fix. The only remedy is to fix the issue in the future version only. 

  • The incidence of insecure deserialization

Incidence deserialization occurs when a React application uses Spring Boot microservices and programmers struggle hard to make sure the code used remains unalterable. To make this happen, programmers generally perform user state serialization. If that’s not done correctly, an attacker can easily figure out the “r00” Java object signature. Using the Java Serial Killer tool, the threat actor can perform remote code execution. 

Examples of Attacks
Examples of Attacks
  1. A hacker identifies the agency's insecure CI/CD pipeline and installs malicious code that gets into production.
  2. Customers unknowingly download malicious code from the agency's replacement servers.
  3. The malicious replacement connects to the customer's environment and the hacker uses it to gain access to the customer's network.

Prevention Methods

Even though this vulnerability is capable of causing damage beyond one’s imagination, measures like continual monitoring, use of efficacious tools/technology, and adoption of best authentication/verification practices can bring great relief.

Here are some of the best and viable preventive methods for A08:2021:

  1. Authentication 

To make sure the software or critical data delivered is coming from a trusted resource, use digital signatures.

  1. User-level Restrictions

It’s important that dependencies as well as libraries used by software/applications are using verified repositories and have restricted access. Users of high-risk profiles are suggested to use a well-inspected repository hosted internally.

  1. Testing

Codes used for software/application generation must go through extensive testing during the development phase and whenever configuration changes are made. It improved the code security and reduced risk of the A08:2021 appearing in OWASP Top 10 2022.

  1. Use of software chain security Aids

Utilizing tools like OWASP CycloneDX or OWASP Dependency-Check helps security professionals to find out whether or not the application/software components feature any sort of vulnerabilities.

  1. Follow Pipeline Deployment Standard

The CI/CD pipeline used for software/application development should feature appropriate segregation, access control, and configuration. This helps in code flow integrity during the entire development and execution phase.

  1. Encrypt and Validate All Data

It's very crucial to make sure that any unencrypted or unverified data is not shared with any unauthorized resource. All data, before sharing, must go through an extensive integrity check or be backed by a digital signature. This practice helps one to spot any tampering or replay related incidents related to your data/serial processes.
